I build products that last.
I help e-commerce, fintech and SaaS companies turn ambitious ideas into robust products — without sacrificing speed or reliability. 10+ years deep in JavaScript/TypeScript.
About
The best architecture is the one nobody notices.
It just works, it scales, and it doesn't wake anyone up at 3 AM. Over 10+ years in the JavaScript/TypeScript ecosystem, I've shipped production software across e-commerce, fintech, SaaS, and developer tooling — backend (Node.js, Python, microservices, AWS) and modern frontend (Vue/Nuxt, React, React Native).
At Wonderbox, I led the full redesign of Wonder-Ecard and migrated the platform to a microservices architecture with reinforced security and observability. At Accor, I designed Node/Python APIs and an NLP engine that improved the hotel search relevance. Entrepreneur at heart, I apply the same rigor to my own products.

Dub Bot
Full-featured Discord bot for the Degen Buds Web3 community. Handles leaderboards, XP tracking, role assignment, moderation automation, and community stats — keeping thousands of members engaged without manual overhead.
GitHub ↗Code Activity
I commit every day.
Not because I have to — because I'm obsessed with the craft. Every session is a chance to build something better, sharpen the solution, or learn something that sticks.
@JRB-y ↗How I Work
Engineering with intent,
not just output.
01 · DISCOVER
Deep Discovery
I start with your business goals, not your feature list. Aligning on outcomes before a single line of code saves weeks of rework later.
02 · ARCHITECT
System Design
Technical architecture that scales. I think through data models, API boundaries, and infra upfront — so you don't pay for rewrites later.
03 · BUILD
Iterative Delivery
Weekly demos, async updates, tight feedback loops. You're never in the dark. Ship fast, learn faster, improve continuously.
04 · SCALE
Ship & Grow
Deployment, monitoring, docs — done right. I hand off code your team can extend, or stay on as your long-term technical partner.
Available · Limited to 2 projects / quarter
Let's build something real.
I take on a limited number of projects each quarter. If you need an engineer who treats your product like their own — let's talk before the slots fill.
