Unity C# Developer & Prototyper
Game UI Integrator & Unity Developer
As a Unity Developer & Prototyper, I write clean C# code and actually know how to make your mechanics feel right. I bridge the gap between your design doc and a working, playable build, so you don't have to deal with spaghetti code or a project that constantly breaks.

Brief initial presentation of myself and my previous experiences.
I script core mechanics in C# and actually know how to optimize them in Unity. Stop dealing with messy codebases or developers who overcomplicate simple features—I handle the whole technical pipeline from prototype to playable build.

How it works
Process Is Everything
Simple, streamlined process is what get's you results
1
Step 1: Core Prototyping & Greyboxing
We start with the core loop. I build out the basic mechanics and player controls using simple shapes so we can test if the game is actually fun to play before anyone commits to heavy architecture or art.
Step 1
2
Step 2: C# Architecture & Systems
Once the prototype feels good, I build out the real logic. I write clean, scalable C# scripts—like robust state machines for combat or custom physics controllers—ensuring the codebase doesn't turn into a tangled mess as the game grows.
Step 2
3
Step 3: Asset Integration & Polish
Here is where the game comes to life. I take your team's 2D/3D art, animations, and VFX, and wire them up natively into the engine, ensuring all the components talk to each other without breaking the core logic.
Step 3
4
Step 4: Optimization & Handoff
You get a stable, playtest-ready build. I use the Unity Profiler to kill frame-drops, manage object pooling for mobile, and hand over a neatly organized project repository that your team can immediately jump into.

My Role: Unity Game developer
The Problem: Tower defense games with real-time grid positioning, unit merging, and continuous enemy waves can quickly become a performance nightmare. Unoptimized code leads to massive CPU lag when dozens of units attack simultaneously, ruining the competitive feel.

The Problem: Tower defense games with real-time grid positioning, unit merging, and continuous enemy waves can quickly become a performance nightmare. Unoptimized code leads to massive CPU lag when dozens of units attack simultaneously, ruining the competitive feel.
My Solution: I coded the entire gameplay architecture from scratch using clean, optimized C# scripting. I focused heavily on data structures for the grid system, seamless unit-merging logic, and high-performance wave spawning. By leaving the UI entirely out of the equation during this phase, I ensured the core math and game loop were bulletproof, responsive, and ready for production scaling.

My Role: Systems & AI Programmer
The Problem: The game relied heavily on unpredictable, randomly generated maps and smart enemies. However, the procedural generation code kept creating broken rooms that trapped the player, and the enemy AI was erratic—either glitching through walls or standing completely still instead of attacking.
My Solution: I designed a modular C# level generation system that guarantees stable, fully traversable maps every single run. Then, I rewrote the enemy AI using adaptive state machines. Now, enemies intelligently track, chase, and ambush the player based on distance and spell-casting triggers, creating a genuinely challenging and bug-free gameplay experience.

My Role: Technical Programmer & Code Auditor
The Problem: The development team had a solid creative vision, but the existing code codebase was full of bugs, broken loops, and unoptimized logic [local]. This caused frequent gameplay glitches, erratic character behaviors, and random frame-rate drops that completely broke player immersion [local].
My Solution: I collaborated closely with the core development team to audit their repository and pinpoint the underlying performance bottlenecks [local]. I refactored unoptimized scripts, cleaned up conflicting game functions, and streamlined their execution pipelines. By resolving these fundamental architectural flaws, I transformed a buggy prototype into a highly stable, completely fluid, and responsive gameplay experience [local]. [1]

Why choose me
The Bridge Advantage
Gain access to a developer who handles both Figma layout and Unity C# logic, ensuring pixel-perfect execution without pipeline friction. No more siloed workflows where design anchors break, programmer handoff drifts, and the final build loses the intended aesthetic.
Fast Prototyping
I build core mechanics quickly using clean C# logic. We get a playable, stable prototype into your hands immediately to test the "fun factor" without wasting weeks on overcomplicated architecture.
Slow Development
Hiring a programmer who over-engineers simple mechanics, getting lost in messy scripts and tangled dependencies. It takes them weeks just to get a basic player controller working.

Siloed Workflows

Client-Centric Collaboration
I build games with your whole team in mind. I set up clean Unity hierarchies and custom inspector tools so your game designers can tweak variables and balance mechanics without ever needing to read my code.
Detached Communication
A developer who writes hardcoded logic in a complete silo. Every time your designer wants to slightly change a jump height or weapon damage, they have to beg the programmer to rewrite the script.

Unoptimized Blueprints
A developer who writes hardcoded logic in a complete silo. Every time your designer wants to slightly change a jump height or weapon damage, they have to beg the programmer to rewrite the script.
Timely Project Tracking
I treat your game like a professional product. I use clean version control, modular C# scripts, and hit milestones on time so the Unity project is always stable, backed up, and ready to scale.
Unstructured & Unreliable Work
Dealing with a chaotic Unity project full of broken prefabs, missing references, and spaghetti code. Every time the developer tries to add a single new feature, three old features instantly break.
Rapid Prototyping Loops
Turning concepts into playable mechanics with fast, agile feedback loops so your creative vision is captured perfectly
Detached Development
Developers who disappear for weeks without updates and deliver final builds that completely miss the original mark.
Timely Project Tracking
I tend to complete the project before the deadline so thatI have room for polishing the project
Unstructured & Unreliable Work
Inconsistent timelines and last-minute changes can compromise quality
Milestone-Driven Delivery
Strict adherence to contract phases, ensuring every UI screen, 3D asset, and script is integrated and delivered on schedule.
Unstructured Chaos
Missed deadlines, feature creep, and last-minute scrambles that blow up studio budgets and delay launch dates.
