Your project,deliveredend toend.
Kodex is a development agency that takes your project from idea to delivery. Mobile apps, custom IT systems, Claude-powered solutions, and full-stack builds — we design, build, and ship it all, end to end.
Built for the industries that don't tolerate failure.
Every industry has its own constraints — regulatory, operational, technical. We've shipped in enough of them to know the patterns that hold and the ones that don't.
Healthcare
Care coordination, patient data platforms, and clinical workflow systems. Built to HIPAA standards, designed for clinicians who don't have time to learn new software.
Fintech
Settlement engines, lending platforms, and compliance systems. Event-sourced, auditable, and built to move money without drama.
Education
Learning platforms, content management, and student analytics. Personalization that respects editorial control — and proves it works with A/B tests.
Logistics
Fleet tracking, dispatch optimization, and supply chain visibility. Real-time telemetry pipelines that turn GPS pings into operational decisions.
Retail & E-commerce
Checkout optimization, inventory systems, and customer data platforms. Conversion-focused engineering with the metrics to prove it.
Energy
Grid monitoring, asset management, and regulatory reporting. Systems that handle high-throughput sensor data and the compliance that comes with it.
Everything your project needs.
Mobile apps, full-stack products, Claude-powered systems, and custom IT — whatever the project calls for, one team owns it end to end, from the first call to launch.
Mobile App Solutions
iOS and Android apps designed, built, and shipped to the stores — React Native and Expo, with push, payments, and offline-first where it matters.
Full-Stack Solutions
Complete web products: frontend, backend, APIs, and databases in one build. React, Next.js, Node.js — from the first screen to production.
Claude & AI Solutions
Claude-powered apps, LLM systems, retrieval pipelines, and agents — designed to be safe, measurable, and put behind real traffic. Not demos.
Custom IT Solutions
Bespoke software for the way your company actually works — integrations, internal tools, ERPs, and the systems that keep you running.
Cloud & Platform
Infrastructure, CI/CD, and cost-aware architecture on AWS and GCP. Terraform, Kubernetes, and observability that earns its keep.
Security & Reliability
Threat modeling, security reviews, and SLOs with the dashboards to prove them. Secure by default, not by appendix.
A process you can watch.
Most agencies treat the process as a black box. We publish ours: four phases, visible work at every step, and a demo every Friday while we build.
Frame
One week of discovery: goals, constraints, existing systems, and what done looks like. You get a written scope and a fixed price.
Design
Architecture, data model, and interface direction — agreed before a line of code. You approve what we build, in writing.
Build
Two-week sprints, a demo every Friday, and a staging environment you can click through. No surprise invoices, ever.
Harden & ship
Automated tests, load checks, security review, then a monitored launch. We stay for the first month after go-live.
Fixed scope
A scope and a price, agreed before we start. Best when the problem is clear and the outcome is measurable.
Embedded team
Our engineers on your cadence, in your tools, accountable to your roadmap — without the overhead of a hire.
Product partner
We own the build end-to-end and tie part of our fee to agreed outcome metrics. Aligned, or we both feel it.
Real problems, quietly solved.
Client names are fictional; the shape of the work is not. Every case below is the kind of project we deliver — and how we'd deliver it.
"They pushed back on scope we didn't need and shipped what mattered. The system has carried fourteen sites for two years without a single drama."
What we believe, in writing.
Five commitments we hold ourselves to on every project. They cost us business occasionally. They've kept our clients for years.
One team, end to end
The people who scope your project are the people who build it — and they stay on it until it's delivered, working and in production.
Delivered means done
Shipped, live, and working for your users — not 'the code compiles' and not 'it works on my machine'. If it isn't in production, it isn't done.
Security is a property, not a feature
Threat modeling and reviews are part of the build, not an add-on you pay for later. We'd rather fix a risk in week two than in production.
Boring reliability, delightful product
The infrastructure is unremarkable on purpose. The product is where we show off — and it never breaks on a Friday.
Opinionated scope, no surprises
We'd rather tell you what not to build. A smaller release that ships beats a roadmap that slips, every single time.
Notes from the lab.
Essays on building AI systems, shipping product, and running the infrastructure that earns its keep — written by the engineers who do it.
AI agents in production: the parts nobody demos
Every demo works on a clean input. Production runs on mess — missing context, adversarial users, and the long tail of edge cases. This is what it actually takes to put an agent on real traffic and keep it there.
RAG that actually answers: retrieval is a product problem
Your model isn't the bottleneck. Your retrieval is. Most RAG systems fail because the data layer was designed for search, not for answers. Here's the pipeline we actually ship.
LLM security is not a prompt problem
Prompt injection gets the headlines. It's also the least of it. The real risk in an LLM system is agency — the tools you gave the model — and the data it can reach. Here's the threat model we actually use.
Platform engineering that earns its keep
Internal platforms fail when they're built for the engineering team instead of for the business. The ones that earn their budget solve one problem: how fast a product engineer goes from day one to 'it's in production'.
Shipping software without the compromise
'We had to cut corners to ship' is a story we hear constantly. It's also usually false — the corners got cut long before the deadline, in the scope, in the reviews, in the definition of done. Here's the delivery discipline that avoids it.
Observing LLM systems: beyond tokens and cost
Your error rate says nothing about whether your LLM product is getting better. Quality in an LLM system is a moving target, and most dashboards can't see it. Here's what we log, trace, and alert on.
Straight answers.
The questions founders and CTOs ask us most — answered the way we'd answer them on a call.
