About Me

The story behind the code

Six years of writing software, learning from production, and shipping things people actually use.

// my-journey

From curious tinkerer to Lead Architect.

I started with Angular and TypeScript at Green Leaf Technology in 2019, shipping enterprise dashboards and learning what production actually demands.

A few years and a lot of pull requests later, I've led frontend teams at QuadRION, shipped Strikeo to thousands of users, and now architect regulatory-grade fintech at Dooit.ai.

Along the way the stack evolved — Angular gave way to React, Next.js, and React Native — but the goal stayed the same: build software that's a pleasure to use and a pleasure to maintain.

Currently

Architecting an enterprise Anti-Money-Laundering platform with real-time transaction monitoring and risk scoring for compliance teams.

// what-i-do

System Architecture

Designing scalable backends, real-time data pipelines, and risk-scoring engines that hold up under production load.

Full-Stack Web

End-to-end products with Next.js, TypeScript, Node.js and MongoDB — from API contracts to pixel-perfect UI.

Cross-Platform Mobile

Shipping iOS and Android apps with React Native and Expo, sharing logic with the web where it makes sense.

Performance & DX

Tightening Core Web Vitals, refactoring for maintainability, and setting up tooling teams actually want to use.

// principles

How I code.

01

Clean code over clever code

Readable today beats elegant tomorrow. I optimise for the next engineer, not for my ego.

02

Performance is a feature

Latency budgets, bundle size, and rendering cost are part of the spec — not an afterthought.

03

Build for the user

Every architectural decision should ladder back to a faster, clearer, or more reliable experience.

04

Always be learning

The stack I shipped on year one is gone. Staying curious is the only durable senior skill.

Have a problem worth solving?

Open to senior engineering, architecture and consulting work — fintech & SaaS especially.
