Architecture for software
that outlasts the hype.
XenneX has been shipping production software since 2014 — web, mobile, cloud, and increasingly AI. We take on projects where architecture matters: complex systems, tight constraints, and the pressure to get it right the first time.
/ engagements
Three ways we work together.
Greenfield Build
You have an idea, a spec, or a rough sketch. We take it from architecture to production — data model, infrastructure, code, CI/CD, and the unglamorous parts nobody else wants to own.
- Full-stack web, mobile (iOS + Android), and cloud
- API design, database architecture, and deployment pipelines
- AI-powered features where they solve a real problem
- Handoff with documentation, or we keep shipping
System Modernization
Hit a scaling wall? Inherited a codebase that scares you? We audit what exists, define a migration path, and execute it without taking the product offline.
- Architecture audit and risk assessment
- Incremental migration strategy — no big-bang rewrites
- Performance, reliability, and observability improvements
- Cloud infrastructure re-architecture (AWS, GCP, Azure)
Architecture Advisory
You have a team but want senior eyes on the decisions before they calcify. We run architecture reviews, produce a technical roadmap, and stay available as you build.
- System and data model review
- Written technical roadmap with prioritized tradeoffs
- Async Q&A and design reviews during the engagement
- One-time or ongoing retainer
Every engagement is scoped to the project. Get in touch and we'll figure out what fits.
/ how we work
The philosophy behind the code.
One architect. No hand-offs.
The person who designs your system is the person who builds it. No junior devs hidden behind an account manager.
Architecture first.
We spend time on the decisions that are expensive to undo before we write a line of production code.
AI where it earns its place.
We integrate LLM features, RAG pipelines, and AI workflows when they solve a real problem — not because it's trending.
Built for maintainability.
Systems get inherited. We write code and documentation that a future engineer can reason about without calling us.
You own what we build.
Full source code, deployed to your infrastructure. No vendor lock-in, no mandatory retainer — just software that's yours.
/ what we build
Every type of project.
Website
A marketing website shouldn't be a side project. We build sites that are fast, accessible, and ready for AI-powered search. Google's AI Overviews draw from the same signals as organic rankings — structured data, crawlability, semantic markup — and we build all of it in from day one.
Web Application
We design the data model, API layer, and frontend in concert — so you don't inherit the technical debt that comes from building those pieces in isolation. From auth and billing to deployment pipelines, we own the full stack.
Mobile App
Cross-platform doesn't mean compromise. We build mobile apps with React Native and Ionic that feel native because the architecture decisions — data sync, offline behavior, navigation — are made intentionally, not as afterthoughts.
Cloud / Backend
The backend is where most projects go wrong. We design systems that handle the load you have today and the load you'll have in 18 months — without over-engineering for a scale that may never come.
AI & Automation
We don't add AI because it's trending. We integrate LLM capabilities, build RAG pipelines, and automate workflows where they solve a real problem — and we build them to production standards, not demo standards.
Architecture Advisory
The most expensive engineering mistakes aren't bugs — they're architectural decisions made under pressure without enough information. We review what you have, identify where the risk is, and give you a written plan you can act on.
/ stack
We use what fits the problem. These are the tools we reach for most.
