I am a Software & Game Engineer with a Bachelor’s in Game Development and expertise in Unity, Unreal Engine, C++, and C#. I specialize in gameplay programming, physics simulation, performance optimization, and scalable system architecture, with experience in custom engines. I also have web development skills in HTML, CSS, JavaScript, Pixi.js, and React, and I am passionate about building efficient, high-quality, and maintainable software.

20+ yrs in Game Dev with a current focus on Unity/C#. AI-assisted Gameplay & Systems architecture, deep debugging, & performance optimization. Fusing 20+ years of software engineering experience with a cutting-edge, AI-driven workflow, I am a developer who thrives on architecting intricate systems and solving deep technical problems. My approach is grounded in creating solutions that are not only effective but also stable, scalable, and maintainable. One of my core strengths is architecting the logic that governs complex game worlds. Whether it's designing sophisticated AI behaviors or building scalable systems for core gameplay mechanics, I excel at turning abstract concepts into well-structured, efficient code. I also have a proven track record as a persistent technical troubleshooter. I am skilled at deep-dive debugging into unfamiliar codebases, recently demonstrated by successfully resolving a critical, month-long issue within a third-party networking library. I have transitioned my workflow to be at the forefront of modern software engineering, making advanced AI my primary development environment. This involves a deep integration with models like OpenAI Codex, Claude Code and Antigravity, which I use for full-cycle development—from architecting systems to generating and optimizing production-ready code. This modern, hybrid approach allows me to deliver robust, high-quality solutions while significantly enhancing project velocity. My foundational experience is broad, covering areas like performance optimization, multithreading, and shader implementation. I am now applying this skill set to the Unity/C# ecosystem, where my recent hands-on work includes optimization with the Unity Profiler, shader development, and networking.

$350K+ earned across 62 Upwork projects. Top Rated. I build AI-powered automation systems, intelligent agents, and data pipelines in Python. What I deliver: • AI Agents & LLM Integration — Building autonomous agents, RAG pipelines, and Claude/OpenAI API integrations that solve real business problems. • Intelligent Automation — From browser automation to full workflow orchestration, I build systems that replace manual processes with AI-driven ones. • Web Scraping & ETL at Scale — Production-grade data extraction systems handling 50K+ products across 40+ suppliers with zero manual intervention. • Full Stack Development — Django/Flask + React, deployed on AWS/Azure with CI/CD. Security-first approach backed by a cybersecurity background (CTFtime rank #31 globally). I don't just integrate APIs — I architect systems where AI does the heavy lifting. Let's talk.
