Full-Stack Developer

I’m a full-stack developer who thinks in balance. I care as much about the structure holding a system up as the surface you actually touch — logic and craft, front and back, two halves of the same thing.

It’s the same balance I love in a good yin-yang — and part of why I built Inkmity, a home for tattoo artists and the people who love their work. Clean lines, bold statements: that’s how I write code too.

              Battlefield: Tanks

              Battlefield: Tanks is a turn-based artillery duel inspired by Pocket Tanks, built entirely from scratch with vanilla JavaScript and the HTML5 Canvas API — no framework and no build step. Two players lob shells across scrolling, destructible terrain, minding angle, power, and gravity.

              • Custom pseudo-3D voxel renderer draws every tank from cuboids with orthographic projection and flat-face shading — no 3D library
              • Procedurally generated destructible terrain with splash damage, a live trajectory aiming arc, per-turn stamina and timers, and a localStorage leaderboard

              Beyond the code

              The Other Half

              The code is only one side of me. The other side is where the code gets its taste.

              Art & Ink

              I’m drawn to people who make things by hand. Tattoo artists turn a blank arm into a story — the yin-yang I keep coming back to is proof of how much a single clean design can mean. That respect for craft is exactly why I built Inkmity, and it’s the same instinct that makes me sweat the details of an interface.

              Games & Play

              I grew up taking games apart to see how they ticked, so at some point I built my own — a tank-duel engine with destructible terrain, written from scratch on a bare canvas. Play is how I learn best: give me a system and I’ll want to know every rule holding it together.
