About me

Building software that grows businesses

Businesses I work with get websites and platforms that don't just look good, they drive real growth.

Why businesses work with me

I've built investment platforms that handle real money, shaped the architecture for supply chain financing, and ship fintech products every day at EFGH. That same rigour goes into every business website and web app I build on the side.

Whether it's a landing page or a custom platform, you get production-grade engineering, not a template with your logo on it.

When I'm not coding, you'll find me running trails or lost in a good book.

Background

Mar 2025 — Present

Senior Software Engineer

Embed Financial Group Holdings

I lead the engineering team's technical direction and co-led ConnectSure, a multi-tenant, event-driven embedded insurance platform on AWS. Templated tenant provisioning turned multi-day onboarding into a one-click spin-up.

I also own the group's web platform: a Next.js corporate site with a typed SEO and AEO layer, a shared design system, and Sanity CMS content behind a single frontend.

On the AI side, I built a compliance pipeline on Bedrock that screens adverse media and regulatory news daily.

Built a subscription-based financial learning platform end-to-end on Next.js and Supabase — CMS-driven multilingual content, Stripe subscriptions, and a real-time community with admin moderation.
