About Me

How I Do It

I build resilient, type-safe products that move from whiteboard sketches to reliable releases without drama.

I build resilient, type-safe products that move from whiteboard sketches to reliable releases without drama. My path runs from soldering homemade PCBs to designing AI-native SaaS. I obsess about predictable delivery: clear contracts, measurable impact, and secure-by-default systems. Every project starts with discovery, ends with a documented hand-off, and ships with guardrails for the next iteration.

My Journey

2010
Early Curiosity in Radio Electronics

Early Curiosity in Radio Electronics

Hands-on experiments with circuits and DIY PCB techniques

Nightly soldering sessions taught me to debug systems component-by-component long before I wrote any code.

Built a methodical debugging muscle from hardware constraints.

First Steps in Software Experimentation

First Steps in Software Experimentation

Game modding, no-code builders, and early scripting

Reverse-engineering .jar games and no-code sites sparked my curiosity for how software behaves under the hood.

Developed a fearless experimentation habit that now drives rapid prototyping.

Low-Level Systems Project: HTTP Server in Assembly

Low-Level Systems Project: HTTP Server in Assembly

Building a server from scratch using Linux x86_64 syscalls

Using most difficult language to code, I hand-coded an HTTP server in assembly to deeply understand memory and syscalls.

Optimized request handling down to raw syscalls and zero-copy buffers.
