High Performance Engineering Performance critical services, distributed systems, and backend components using Go, Rust, C, and C++ when speed and reliability matter. Core technologies: Python, TypeScript, JavaScript, Go, Rust, C/C++, SQL React, Node.js, FastAPI, Django, REST, GraphQL PostgreSQL, MySQL, MongoDB, Redis OpenAI API, Anthropic API, RAG, AI agents, LLM workflows AWS, GCP, Docker, Kubernetes, Terraform, GitHub Actions Why clients work with me: I write clean, maintainable, production ready code I communicate clearly and give regular progress updates I can own a project end to end or join an existing engineering team I focus on solving the business problem, not just writing code I care about reliability, scalability, and long term maintainability Whether you need an MVP, backend system, AI automation tool, cloud deployment, or a full product build, I can help you design it properly and ship it with confidence. Send me a message and I will be happy to discuss your project.

I specialize in workflow automation and pipeline development primarily for computer graphics, video, and image processing - drawing on years of experience as a technical director at an animation studio. I'm always happy to discuss your task or project and explore solutions together. / __what_i_deliver__ - Automation of production processes, especially where the use of computer graphics is required - Tool & plugin development for 3D applications, building USD-based pipelines - Render farm setup, cloud rendering infrastructure and cost optimization - Synthetic 3d data generation, parametric modeling, Gaussian splatting - Image/video processing: custom ComfyUI workflows, gen ai image/video pipelines, ai motion capture - SaaS Full-stack dev, DevOps/FinOps, serverless GPU deployment - Blockchain apps, smart contracts dev - Reverse engineering, binary analysis, decompilation - R&D, mathematical tasks, algorithm implementation - Embedded/microcontroller programming: ESP32, STM32H7, Raspberry Pi and more / __tech_stack__ - Python, С/C++, TypeScript, Dart, GLSL - Backend: FastAPI, Node.js/Express, NestJS, MongoDB, PostgreSQL, Redis - Frontend: Qt (PySide), Svelte, React, Next.js, Flutter, Three.js, WebGL - ML/Generative: ComfyUI, PyTorch - Computer vision: OpenCV, MediaPipe, SAM, Yolo, ResNet - AI agents: LangGraph, Google ADK, Anthropic API - web3: Solidity, Hardhat, Foundry, OpenZeppelin, Dynamic.xyz, Alchemy, IPFS - Infra cloud: AWS , GCP, Hetzner, Railway, Vercel - Infra GPU cloud: Modal, Runpod, vast.ai, Koyeb - Infra Devops: IaC, Docker, K8s, Terraform, MinIO, NAS, S3 - RE: Frida, Ghidra, IL2CPP / __dcc_&_pipeline_tools__ - Blender (bpy, GeoNodes), Autodesk Maya (mel/python/OpenMaya), SideFX Houdini (hython, hscript, HDK), 3ds Max (maxscript), Unreal Engine, Foundry Nuke (incl.
