I build full-stack systems and the architecture behind them — Node.js and React end to end, event-driven pipelines, and the AWS/GCP infrastructure they run on.

About
I build products end to end — architecture, backend, and the UI on top.
Twelve-plus years across the full software development lifecycle: greenfield architecture, production ownership, and the migrations in between. That work has spanned the full stack — Node.js services, React and Angular front ends, relational and NoSQL data stores, and cloud infrastructure on AWS and GCP — for products in healthcare, fintech, e-commerce, and enterprise SaaS.
I care about clean APIs, maintainable codebases, and systems that are legible to the next engineer. Alongside the hands-on work, I spend time on technical leadership — design reviews, mentoring, and keeping a team aligned on architecture and delivery standards.
More recently, that curiosity has extended into applied AI — integrating Google's Gemini API at Emtrain to power text-to-image generation directly inside the platform. I treat a new model API the same way I treat a new cloud service: understand its constraints, ship something real with it, then decide if it earns a permanent place in the stack.

What I argue for in design review
If we end up working together, these are the arguments I’ll make in the room.
Systems-thinking first
Every design decision is made with the whole system in view — scalable design, clean APIs, and outcomes I can measure, not just ship.
Own the architecture, mentor the team
Technical ownership of system design and code quality goes hand in hand with design reviews and mentoring — the architecture only holds if the team understands why it looks the way it does.
Cloud-first, event-driven
AWS and GCP are tools for decoupling, not defaults. Queues, scheduled functions, and event buses go in where they remove a bottleneck, not everywhere.
Clean APIs, maintainable code
Node.js, TypeScript, React, and SQL are the daily stack, but the bar is the same regardless of language: an API and a codebase the next engineer can actually read.
