Systems Architect and full-stack engineer with 5+ years building production software. I help universities, government offices, and SaaS teams replace fragmented tools with platforms built to scale — designed, built, and deployed end to end.

ABOUT

I build the platforms organizations run their work on. Most of it starts where quick fixes end — when a team has outgrown spreadsheets and disconnected tools. I design the architecture, build it across the full stack, and own it through to production — built to grow instead of being rebuilt.

SURI

System for Unified Research Information — one platform managing 15,000+ records across 50+ users, unifying registration, document management, reporting, and approval workflows that previously ran by hand. Built API-first on Laravel, it replaced manual spreadsheet compilation with reporting that runs in seconds.

FAQ

Frequently
asked
questions.

Can't find what you're looking for? Reach out directly and I'll get back to you.

What kind of work do you take on? +

Custom platforms and systems — research and operations tools, internal software, multi-tenant SaaS, and AI-assisted workflows — for organizations that need software they can rely on long term. I take on the architecture and the build, not isolated tickets.

Do you handle the whole system, or just part of it? +

The whole system — architecture, full-stack development, AI integration, and the infrastructure it runs on. You work with one engineer who owns the outcome end to end.

What if you're unavailable mid-project? +

Continuity is built into how I work: clean documentation, version-controlled code, and reproducible, deployable infrastructure. The systems I build aren't locked in my head — they can be picked up, handed off, or maintained by another engineer without starting over.

What does a project cost? +

Every project is scoped individually based on requirements, complexity, and timeline. After an initial discussion, I'll provide a clear proposal with scope, deliverables, and pricing.

How do you handle AI features responsibly? +

I build AI on controlled-response architectures: it answers from approved information and hands off to a human when something falls outside its scope, rather than guessing. AI should reduce risk, not add it.
