Custom websites
Company sites, storefronts and customer portals for small, mid-size and large businesses: fast, accessible, easy to update, and tied into the systems behind them.
Enterprise integration, custom applications and websites, and business solutions for small, mid-size and large companies, hosted in-house, on-premises or in the cloud. AI is part of the toolkit, on whichever leading model fits the job. One studio from the database to the screen, with more than 25 years of delivery.
EDI in X12, EDIFACT, HL7 and HIPAA. AS2, SFTP, REST, SOAP, JMS and file exchange with trading partners and VANs. Oracle SOA Suite, Service Bus, B2B and WebLogic, Boomi, and IBM WebSphere integration. Oracle E-Business Suite order to cash, Oracle CPQ, Fusion Cloud, Salesforce and SAP. Migrations across every SOA generation, from SOA to Boomi, and from Oracle to PostgreSQL.

Back ends in Java (servlets, JAX-RS, JSF, ADF), Node.js and Python on WebLogic and beyond. Front ends from websites and single page dashboards to Android and iOS apps, Chrome extensions and desktop line of business applications.

Environments stood up and kept running, in-house, on-premises or in the cloud: WebLogic domains, VMware, sites and services behind Cloudflare, monitoring and alerting, ticketing integration, and deploy pipelines in Ant, WLST and PowerShell.

Oracle, SQL Server, PostgreSQL, Sybase and SQL Anywhere: schema design, PL/SQL and T-SQL, tuning, GoldenGate and Informatica, and scheduled jobs that collect, score and report unattended.
Off the shelf platforms ask a business to reshape its process around someone else's product, then charge for every seat, every module and every year. Modern engineering, with AI tooling where it speeds the work, changes the arithmetic. For small, mid-size and large companies alike, we design and build around the way you actually work, deliver in weeks rather than quarters, and hand you software you own outright, running wherever you choose.

Company sites, storefronts and customer portals for small, mid-size and large businesses: fast, accessible, easy to update, and tied into the systems behind them.

Internal CRMs, point of sale systems, ordering, inventory, scheduling and approvals, shaped around your own process instead of a vendor's.

Apps for customers, field teams and staff, working offline where they need to and talking to your own back end, not a third party's.

Run it on your own servers, in your data centre, or in the cloud you prefer. We set it up, secure it, monitor it and keep it running.
A gallery of working prototypes of the real screens, on your data shapes, so decisions are made by looking rather than by reading specifications.
Modern tooling, AI included, writes and refactors at speed; senior engineers set the architecture, review every change and own the result. Speed from the tooling, judgement from experience.
Automated tests and regression harnesses written beside every feature and shown to fail without the fix, so the next change does not quietly break the last one.
Few dependencies, readable code, deployment scripts, monitoring and documentation, so it can be run and extended by your team or ours.
Where a platform is the right answer, we say so, and integrate with it cleanly. The standard we hold either way: secure by default, accessible, observable in production, and simple enough to hand over.
Integration work ends in a screen that people rely on every day, and these six samples, all built on invented data, show the kinds of dashboards that come out of it.
| Severity | Flow | Env | Error | Age |
|---|
| Partner | Document | Dir | Control | Status | Time |
|---|
| Claim | Provider | Service | Billed | Paid | Status |
|---|
Lab, 12 minutes above threshold, compressor cycling.
IDF 2, 3 sensors buffered on Gateway A.
Loading bay, open 6 minutes, closed by dock staff.
Main panel, within contract demand.
| Record | Rule | Finding | Severity | Source |

One part of the toolkit, built like everything else: connected to real data and held to rules that live in code. We work across the leading models, Claude, ChatGPT, Gemini, Copilot, Llama and Mistral, hosted or run on your own hardware, and choose by the task, the cost and where your data is allowed to go. A model decides what to try next; hooks, scopes and schemas decide what it may actually do.
Agents on Claude, ChatGPT or Gemini that plan, call your tools and hand focused work to subagents. Hooks enforce the limits in code: amounts, approvals, who may touch what. Anything the agent should not finish goes to a person, with the context attached.
Model Context Protocol servers that give AI a narrow, typed view of E-Business Suite, databases and document stores. It reads what the task needs and writes only what it is allowed to. Nothing else is reachable.
Invoices, orders and forms read into JSON that must pass a JSON schema before anything uses it. A field that fails the schema or reads with low confidence goes to a person for review instead of into your system.
AI-assisted engineering. Coding assistants such as Claude Code, OpenAI Codex, GitHub Copilot and Gemini configured for your repository: project rules, hooks, and automated review running in CI.
$ review /rules hooks tests CI
The model chooses the next tool. Your hooks, schemas and server scopes decide what it is allowed to do with it, and a person sees whatever falls outside those limits.
All of it built by KadTech. Several are live and linked; the rest run every day on our own machines.
A configuration-driven orchestration framework for EDI and XML trading partner flows. It creates real orders and invoices in Oracle E-Business Suite 12.2 through Oracle's own public APIs and runs order to cash end to end.
Reads, validates, decodes and converts X12, EDIFACT and HL7 against their implementation guides. Validation names the exact element at fault; 999 and 997 acknowledgements are written from the findings.
Inventories Oracle SOA composites and classifies every construct against Boomi's shapes and connectors, so a migration is estimated from evidence. Standard Python only, with tokenised reports so client source never leaves the client's machine.
A free study guide for the Claude Certified Architect exam: all 30 task statements, practice in the six exam scenarios, a timed mock exam and decision drills.
kadtech.net/claude-code-architectA school dashboard for families: grades, homework and study pulled together from the district's systems, plus a free public library of 164 worksheets and practice generators aligned to state standards.
studyhall.kadtech.netThe supervisor for every service KadTech runs. It starts, watchdogs and restarts the application servers, Node services, databases and the Cloudflare tunnel, with one status dashboard.
FlipRadar scores resale deals on margin and ease of pickup. DealRadar runs one search across Amazon, Walmart, Target, Best Buy and eBay. HavenRadar covers rental houses in 32 curated markets. GadgetRadar reads about 30 technology feeds every 90 minutes.
One Chrome extension that merges six tools, so one icon replaces six.
A formatter that proves it changed nothing but layout, by re-reading its own output and comparing every token.
The detail a technical buyer asks about first. Every item below is built, running and tested in our own integration estate, against a real Oracle E-Business Suite instance.
A configuration-driven orchestration platform for trading partner flows. Routes, partners, maps, enrichment and validation rules are data, not code, so a new partner or document is configured rather than programmed. It creates real orders and invoices in Oracle E-Business Suite and runs order to cash end to end.
Governments across Europe are moving business invoices from PDFs and paper to structured e-invoices that a machine can read and a tax authority can check. We produce invoices that meet the European standard, EN 16931, and deliver them in the formats and channels the mandates require.
The full claims cycle, built and exercised: enrollment in, claims out, and every answer a payer sends back, reconciled and balanced.
A standards engine that reads a document the way its implementation guide says it should be read, and explains every finding in plain language.
The design patterns behind the systems we build, chosen for the problem rather than the fashion. Each is one we have put into production and can explain the tradeoffs of.
KadTech brings more than 25 years of enterprise integration and application delivery. Our work is the systems in the middle: the interfaces that connect ERP, order management, quoting, claims, billing, connected devices and trading partners, and the databases underneath them. We carry a project from architecture through build, migration, cutover and production support, and we stay for the runbook, the training and the handover.
Oracle SOA Suite and Service Bus across every generation from 10g to 14c, with the WebLogic domains, adapters and B2B beneath them. Service Bus estates rebuilt with automated tests around the key flows, and phased moves to Boomi with both platforms running side by side and reconciled before each flow was retired.
Well over a hundred trading partner integrations in X12 and EDIFACT: orders, acknowledgements, ship notices, invoices, remittance and eligibility. HIPAA enrollment, claims, claim status and remittance templates, AS2 with signed receipts, VAN onboarding, Oracle B2B end to end, and EU e-invoicing to EN 16931.
Oracle E-Business Suite order to cash through its public APIs, XML Gateway and e-Commerce Gateway, plus Oracle CPQ, Oracle Fusion Cloud, Salesforce and SAP (ALE, BAPI, RFC and IDoc), with the business rules and decision logic that sit between them.
Device to cloud and cloud to on-premises data feeds for networked medical equipment, an aggregation engine for raw device data and log files in real time and in batch, and the tracking front ends field teams work from.
Oracle from 8i to 21c including Exadata: schema design, PL/SQL packages, partitioning, tuning and benchmarking, with batch work cut from hours to minutes. GoldenGate replication, Informatica, SQL Server, PostgreSQL and Sybase, and migrations from Oracle to PostgreSQL proved equal before the switch.
One operations view across every integration a business runs on, read from the platform itself, with ticketing, shared mailboxes and chat beside it. End to end order tracking, server side validation testing, stuck record recovery, alerting within minutes of a fault, and maintenance calendars built from captured notices.
Trading floor surveillance and market manipulation analysis over very large daily volumes, feeding enforcement cases, and claims processing platforms extended and tuned for throughput.
Websites and customer portals, Java web applications on WebLogic, Node.js services, single page dashboards, mobile apps, Chrome extensions, and a long history of desktop line of business applications, each built to be run and supported, not just shipped.
What we have built with and run in production over the years, from the database to the screen, with AI tooling beside it.

Everything above is what we have built with and run in production. It is not a boundary. With modern tooling, AI included, we read a platform's documentation, its APIs and your own code in days rather than months, and write in the languages and conventions your team already reviews. So we work inside the stack you have, or help you leave it. We do not sell a platform or a model, so the advice is not tied to one.
Whatever it is, and whichever vendor it came from. The list above is our history, not a requirement.
Speed from the tooling. Senior engineers set the architecture, review the output and own the result.
We build inside what you already run: your platforms, your languages, your code review and your deployment pipeline. Nothing new to license, install or learn. Our tooling shortens the way in; your standards decide what comes out.
If you are weighing a change, we assess it plainly: what to keep, what to replace, what it costs and what it risks. Then we run the old and the new side by side and cut over when they measure equal, as we have done from Oracle SOA Suite to Boomi and from Oracle to PostgreSQL.
Either way the code is readable, tested and documented, and yours to run.
A website, a CRM or POS system, an Android or iOS app, a trading partner flow, a migration, an AI assistant inside your systems, or a dashboard that pulls it all together. A short note is enough to start.
