About Me

Hi, I'm Sean, a software engineer with four years of experience specializing in early-stage product-focused startups.

My journey into software engineering began unconventionally – self-teaching JavaScript during my A-levels and landing my first role as a founding engineer at Human Lambdas (Seedcamp backed) at age 18, where I contributed to building distributed data labeling infrastructure.

Since then, I've worked across various exciting projects: developing AI-curated learning platforms at Kimo, creating data analysis UIs at DataZoo, and most recently, leading software engineering initiatives at a stealth startup where I've implemented real-time user engagement systems using Go and Next.js.

I've taken time to deepen my theoretical foundation in Computer Science, particularly focusing on Data Structures & Algorithms. This dedication has led to ranking in the top 4% globally on LeetCode, and achieving top 0.8% placement in recent competitive programming competitions with over 17,000 participants.

My recent work includes developing Eloquent, a cross-platform mobile application for language learning that leverages locally-run LLaMA 3, and contributing to environmental sustainability through Recirculate Systems' innovative reusable cup tracking system.

Outside of tech, I embrace a diverse lifestyle as a Digital Nomad, engaging in Mixed Martial Arts and Chess. I'm driven by tackling complex challenges and creating impactful solutions across various domains.
