Hi, I'm Jackson Fernando 👋

I'm a software engineer with 6+ years of experience building products across the financial, insurance, and telecommunications industries — from digital banking platforms to telco apps and insurance systems.

I enjoy crafting clean, scalable backends and have a good eye for the full stack. I'm always keen to learn new tools and solve meaningful problems.

🚀 Featured Projects

a-kit  !Go

A CLI tool that scaffolds production-ready Go microservices from protobuf definitions (Google API style) — no protoc needed. Define your service in a .proto file and a-kit generate produces handlers, services, repositories, mocks, and unit tests, all wired up and ready to go.

---

carpark  !Java !Spring Boot

A REST API that finds the nearest available car parks to any location using Singapore government open data. Features real-time availability updates (every 15 min), SVY21→WGS84 coordinate conversion, Redis geospatial caching, MySQL spatial indexing, and streaming batch ingestion — processing 2,000+ car parks in under a second.

---

interpreter-using-golang  !Go

A fully functional interpreter built from scratch in Go**, following Thorsten Ball's *Writing An Interpreter In Go*. Implements a complete pipeline — lexer → parser → AST → evaluator — with a working REPL. A deep-dive into how programming languages work under the hood.

---

interpeter-using-c  !C

A complete implementation of the Lox language in C as a bytecode VM, following Robert Nystrom's *Crafting Interpreters* (Part III). Covers the full language — closures, garbage collection, classes with inheritance, and a native REPL — all built at the metal with no dependencies.
