Toronto, ON · Full-Stack Engineer & CTO

Hi, I'm Alwin. I build products people return to — from pixel to pipeline.

Ten years building software end-to-end — React and Next.js on the frontend, Node and Python on the backend, serverless infra, and LLM integrations. Currently CTO and sole engineer at a Toronto AI startup, owning every layer of the stack.

About

I build across the full stack — UI, APIs, data models, infrastructure, and AI integrations. My roots are in frontend architecture, which means the interfaces I ship are as well-engineered under the hood as they look on screen. Over ten years I've delivered production systems across insurance, logistics, and wellness-tech, taking on more of the stack at every step.

Outside of work I'm a husband, a follower of Jesus, and a stubbornly curious human. I love exploring new places, new ideas, and new corners of technology — usually with a coffee in hand and one too many browser tabs open.

I care about clarity over cleverness, saying what I mean to the people I work with, and building things that hold up long after the first demo.

CTO / Co-Founder
WorkingAs1 Inc. · Toronto, ON · 2024 — present

Sole engineer across two AI products — a conversational wellness assessment and a meeting-intelligence tool — both taken from zero to production. Own the full stack: Next.js + Redux frontend, FastAPI backend, LangChain + Groq AI flows, and serverless infrastructure migrated from a legacy Python/Django monolith.

Delivered a real-time UI that streams and reacts to model state, established end-to-end test coverage with Jest + Cypress, and unlocked live reporting after the infra migration. Operating as both engineer and founder has made me sharper at scoping, prioritising, and shipping things that matter — fast.

WorkingAs1 — wellness platform & meeting intelligence

Component library — internal, with the design team
