Open to new roles — remote or Colombo

Software engineer who ships and measures.

I build full-stack products end to end — Laravel, Spring Boot and Node.js on the server, clean responsive interfaces on top — and I am finishing an MSc in Data Science & AI so the data side is never someone else's problem.

Remote delivery for a Japan-based team

What I do

Three things I am genuinely good at

Full-stack product work

Whole features, not slices: schema design, API, interface and the deploy that puts it live. Most recently PHP, Node.js and Next.js delivered fully remote for a team in Japan.

LaravelSpring Boot Node.jsAngular

Integrations that hold up

Moving data between systems where a silent mismatch is expensive. I built and reconciled Shopify and third-party API pipelines, checking every batch for completeness rather than trusting the happy path.

REST APIsShopify API MySQLCI/CD

Applied machine learning

Training models, structuring and annotating the data that feeds them, and evaluating the output against a real accuracy bar — the subject of my MSc and of my award-winning final-year thesis.
