Backend, distributed systems and developer tooling. I've migrated 200+ legacy APIs, shipped a microservice video platform and built LLM-powered dev tools. Currently engineering at rtCamp.

[02] Selected work

Built to carry load.

Each project started from a constraint, not a stack. Here's what I was solving for, what I traded away, and the evidence it works.

code-grader / backendFeatured project
Code Grader interface: code editor beside complexity, readability and optimisation scores
01AI/ML · Developer Tools

Code Grader

LLM-backed grading service that scores submitted code on correctness, complexity and style — and explains why.

Constraint

Evaluate submitted code asynchronously while keeping feedback understandable for learners.

Tradeoffs
  • LLM feedback over static checks alone, for more explanatory reviews
  • Grading lives in a backend service, decoupled from the interface

Vimero

Service-oriented video platform. Queue-backed transcoding keeps expensive media work out of the request path while the UI stays responsive.

Analytics API

Activity and engagement dashboard. Aggregation stays server-side behind a REST boundary, so components only render — never reshape — data.

Snappio Backend

Social and chat backend pairing WebSocket messaging with durable relational persistence — chat that isn't treated as throwaway state.

PeerMessaging

Messaging and video calls over direct browser connections — no relay backend ever sees the message content.
