About

Engineer who ships production systems, not demos

I design and build the backbone of real products — data models, APIs, real-time pipelines and the cloud they run on — then wire clean front ends on top.

I'm a Senior Software Engineer with 6+ years of experience architecting scalable backend systems, real-time platforms and IoT-integrated applications. I've delivered across fintech, logistics, SaaS and e-learning — from an offline-first pharmacy ERP to a real-time truck-tracking platform ingesting telemetry from GPS trackers, dashcams and ELDs.

My core stack is Node.js, NestJS and Express on the backend, React, Next.js, Vue and Nuxt on the front end, and Laravel where a PHP codebase fits best — backed by MongoDB, PostgreSQL and Redis, deployed with Docker and CI/CD on AWS and Azure.

I use AI tooling — Claude, ChatGPT, GitHub Copilot and Cursor — to move faster while keeping code clean, reviewed and production-grade.
