I work on real-time 3D applications built with Unity and Unreal Engine, focusing on games, simulations, and AR/VR systems that are intended to run reliably in production. My experience includes desktop and mobile games, immersive environments, and simulation workflows such as Microsoft Flight Simulator (MSFS). Tech stack: - Unity (C#), Unreal Engine (C++), AR/VR development, MSFS SDK, real-time simulation logic, environment and level development, networking and multiplayer systems, replication and synchronization, shader development, Niagara VFX, and performance profiling and optimization. Audio systems built with Wwise (spatial and event-driven audio). - Mobile development with Swift and Objective-C (iOS), React Native and Flutter (cross-platform). - Supporting tools and languages include Python, custom engine plugins, editor tools, and external API integration. - Target platforms include Windows, iOS, Android, desktop, and XR devices. A significant part of my work is focused on environment realism and interaction, where visuals, audio, effects, and networking must work together. This includes lighting, terrain, VFX using Niagara, shader tuning, multiplayer stability, and audio behavior that supports immersion rather than distracting from it. I also build mobile applications that act as companion tools, dashboards, or control interfaces for games and simulations, often connected to real-time systems or multiplayer backends. I prefer clear requirements, steady progress, and solutions that remain stable and maintainable over time. If you need help building, finishing, or improving a Unity, Unreal, or mobile project with multiplayer or simulation requirements, I can step in and handle it properly.

High-performance backends. Decision engines. AI factories. Computer vision. Real-time systems. From UI/UX-heavy MVPs to full-stack platforms built for the traffic that comes after launch day, not just during it. Rust, C++, and 5+ languages. 100,000+ concurrent WebSocket connections -- in production. A 12-week roadmap shipped in 4. 30 senior engineers. Dedicated project teams, not rotating freelancers. Every engagement starts with a paid Discovery phase -- we scope the architecture before we write a line of code. Not a fit: no-code workflows, or projects solvable with Zapier. WHAT I BUILD - High-Performance Backends: Production backends with actix-web, axum, and Tokio -- millions of requests/day, zero GC pauses. REST, GraphQL, WebSocket, and gRPC services for throughput and latency-sensitive workloads. - Full-Stack Platforms: React, Next.js, TypeScript frontends with production backends -- SaaS, MVPs, and custom web applications from architecture to deployment. Designed for 1K to 100K concurrent users without a rewrite. - Autonomous AI Agents: Agentic pipelines with OpenAI and Anthropic Claude -- lead qualification, data analysis, customer support running 24/7. Multi-step reasoning, error recovery, state persistence. 11+ projects for one client. - Computer Vision: Object detection, tracking, real-time inference, OCR, document processing -- CUDA-optimized, deployed as production APIs or edge devices. Not Jupyter notebooks. - Real-Time 3D & Visualization: WebGL and WebGPU rendering -- product configurators, data dashboards, architectural viewers at 60fps in-browser on mid-range hardware. - Data Pipelines: Rust-native processing with Polars and DataFusion -- replacing Python/JavaScript bottlenecks. Kafka streaming, PostgreSQL persistence. - Cloud & Infrastructure: AWS, GCP, Azure with Terraform and Kubernetes -- auto-scaling, zero-downtime deployments, infrastructure-as-code. RECENT OUTCOMES - Crypto trading platform dropping connections above 8,000 users. Rebuilt proxy in Rust, Tokio, Kubernetes -- 100,000 connections at under 10ms, zero crashes. - GovTech blockchain payment router on Go. Rebuilt IAVL Tree in Rust -- 20–30% faster, Clutch-reviewed (Alex Kampa, AZKR Research). - Recruitment team spending 4 hours daily on manual data entry. Built automated extraction and processing pipeline -- 95% reduction. - Data analytics platform hitting memory limits in JavaScript. Replaced core with Rust and Polars -- 5x faster processing, 70% lower memory. - Blockchain gaming 3D pipeline loading in 8+ seconds. Rebuilt within 4GB RAM budget -- 45% faster, Clutch-reviewed (Ruslan Varets). TECHNOLOGIES - Systems & Backend: Rust, C++, Python, TypeScript, actix-web, axum, Tokio, Node.js, WebAssembly - Frontend: React, Next.js, TypeScript, Tauri, Dioxus - AI & Agents: OpenAI, Anthropic Claude, Hugging Face, LangChain, RelevanceAI - Graphics: WebGL, WebGPU, OpenGL, Vulkan, three.js, GLSL/WGSL shaders, bevy - Vision: OpenCV, CUDA, PyTorch, TensorFlow, Keras, Mediapipe - Data: Polars, DataFusion, PostgreSQL, Kafka, Snowflake, Apache Arrow - Cloud & DevOps: AWS, GCP, Azure, Terraform, Kubernetes, Docker, GitHub Actions - Networking: WebRTC, LibP2P, QUIC, WebSocket, gRPC Delivery: Discovery → Architecture Review → Platform Build → Performance Testing → Production Deploy → Runbook Handoff. Fixed scope per phase. This profile is for engineering teams building production platforms under real load. Send your project brief -- I'll reply within 48 hours to assess fit.
