About

I'm a Unity Game Developer with 2 years of experience building high-performance ad simulations for top-grossing mobile titles like Royal Match and Fishdom, focused on doubling performance metrics while cutting production time by 70%.

I've scaled a creative team from 4 to 20+ developers and produced the highest-performing Royal Match Unity ad on the team with 3 IPM. The work that stuck was always the stuff where I actually understood why it performed, not just that it did.

Outside of work you can usually find me climbing, playing video games, spending time with my cats, or tending to a growing collection of plants.

    3 IPM - highest-performing Royal Match ad in-team

    Analyzed competitor ads and tracked IPM across all company creatives to figure out what actually drove installs, which led to producing the highest-performing Royal Match Unity ad on the team. Ran A/B tests isolating single variables like backgrounds, color schemes, and interactions, measured IPM impact per change, and compounded winning elements into new concepts. Grew the Unity creative team from 4 to 20+ developers, mentoring juniors, writing concepts, fixing technical issues, and maintaining quality standards across concurrent client deliveries. At peak, overseeing 50-60 ad concepts per week across multiple client titles.

    Unity Game Developer @ Replai

    Cut production time by 70% for iteration concepts

    Built gameplay systems for ad creatives across Royal Match, Fishdom, Hero Wars, Candy Crush, and Slotomania, implementing player movement via Unity Splines, game logic, UI, VFX, and audio. Optimized Fishdom's interaction system by replacing per-object colliders with radius-based distance checks, pushing frame rate from 20 to 70 FPS across hundreds of simultaneous objects. Implemented Unity DOTS to simulate 20,000+ interactable objects with real-time collision. Designed a real-time Unity rendering pipeline for Royal Match fluid simulations that replaced Blender and render farm workflows, cutting production time by ~70%. Built a Unity Editor tool that brought asset setup down from ~1 hour to ~10 minutes per concept. Producing 15-20+ concepts per week across multiple titles.

Royal Match

Urgency-driven match-3 mechanic

Brief

Make the match-3 mechanic feel urgent and consequential — not a casual puzzle but a race with something real at stake.

The Hook

The king is trapped and toxic is rising. The mechanic explains itself — match fast, stones fall, toxic clears. No tutorial needed. The viewer reads it in seconds and the pressure is immediate.

Key Decisions

  • Led with the king in danger so the match-3 has a reason — every move is for something, not just points
  • The cause-and-effect of matching → stones falling → toxic clearing is visible without any UI explanation
  • Ended on a fail — the toxic wins, the king doesn't make it. Leaves the viewer wanting to fix what they just watched

What I Rejected

A clean win ending would have closed the loop too neatly. The fail keeps the tension open and puts the viewer in the position of the player.
