Roblox developer (Luau) — server-side systems

A full live-ops layer for a football card-collecting game: coin economy with sources/sinks analytics, pack gacha with pity counters, in-game purchases with receipt idempotency, album pass, daily rewards, idle and offline income with AFK caps, cosmetics, badges and referrals — plus a multi-phase onboarding tutorial with funnel metrics.

Lead developer & level designer — also led QA

A custom Fortnite island with four interconnected minigames — a time-trial race, an escape room, parkour challenges and a final boss battle against a mad scientist and his minions — tying mechanics and progression to the narrative goal of recovering the Formula X. I ran the full development and level design, then led the testing that kept the island stable through a worldwide event.

Sole developer

28 gameplay services on my own: physics platforms, geysers, snowballs, a hammer mechanic, deep snow, checkpoints, progression, leaderboards and anti-exploit protection — plus the shared service framework behind the wider multi-place experience, with place-to-place travel, cinematics and a dialogue system. Written in typed Luau with object pooling and safe shutdown saves.

QA lead & consultant

Test plans and quality gates for live branded islands: Domino’s Red vs Blue (team deathmatch with restaurant capture, power-ups, progression and achievements), Road Test Royale for The General (timing and penalty systems, three locations, vehicle unlocks), and The Glitch Zone Wars for Twitch (16-player squads, objective rounds, random weapon balance, XP and server stability). Functional, balance and stability testing, plus two-stage fix verification before every client delivery.

Developer & QA lead

An immersive virtual space for Visa to host live events: I optimized the 3D assets and scene performance, refined the interactive systems, and ran the testing that kept the venue stable and smooth with an audience inside it.

Developer

Several interconnected experiences around one sustainable house of the future: web-based augmented reality opened from a QR code with no app download, two VR applications (full-scale house exploration and guided meditation), an interactive web journey with minigames, and a tablet app with 3D visualization and real-time effects. I also helped integrate an AI chatbot on the OpenAI API to answer visitors’ questions.

Developer — physical-to-digital systems

Children coloured a paper bear, placed it into a playful “oven” installation, and watched their own drawing come alive in a shared virtual world on a big screen. I built the systems connecting the physical interaction to the real-time digital result, making sure the translation was faithful and the whole thing stayed stable in front of a live audience of small children.

Co-creator — gameplay & QA

Gameplay systems, progression and difficulty balance for Bubble Hero, a wave-survival game taken from a 48-hour jam build to a public release. Before that I self-published two commercial Android titles, SodaRocket Challenge (2019) and Myth Pets (2020), handling design, development, testing and store release on my own — and I keep working on original IP such as the roguelite Chrono Leaf.
