Software Engineer with 5+ years of experience designing and shipping full-stack web applications across fintech, retail, and healthcare domains. Skilled in architecting scalable multi-tenant systems, leading technical scoping for client engagements, and leveraging AI-assisted development to accelerate delivery without compromising code quality.

I own features across the full software development lifecycle, from requirements gathering and technical design through testing, deployment, and production support. Most of my work lives close to the client: translating ambiguous business requirements into data models, system diagrams, and technical roadmaps.

2025IoT

IoT water monitoring system

An end-to-end system that monitors tank levels and flow across a PG, detects supply events and possible leaks, and lets the owner control pumps remotely. ESP32 nodes publish telemetry over MQTT to a NestJS backend, which stores it in TimescaleDB and pushes live updates to an Angular dashboard. Built software-first against a simulated device fleet, with per-device TLS auth and five documented architecture decisions.

A sim-racing leaderboard app for Assetto Corsa, ACC, and EVO.

Players compete on global and friends-only boards and get push alerts when their time is beaten.
