I help companies get hard C++ work done right the first time — multithreaded backends, performance-critical code, and AI features that hold up in production.

I build high-performance C++ systems - network servers handling thousands of concurrent connections, security solutions processing millions of events, trading platforms with 5μs latency. 19 years of experience, $1M+ earned on Upwork, 100% Job Success. 𝗦𝘆𝘀𝘁𝗲𝗺𝘀 & 𝗡𝗲𝘁𝘄𝗼𝗿𝗸 𝗣𝗿𝗼𝗴𝗿𝗮𝗺𝗺𝗶𝗻𝗴 Client-server applications, proxy servers, high-throughput data processing. I write cross-platform code that runs identically on Windows, Linux, and Unix. 𝗖𝘆𝗯𝗲𝗿𝘀𝗲𝗰𝘂𝗿𝗶𝘁𝘆 𝗦𝗼𝗹𝘂𝘁𝗶𝗼𝗻𝘀 Privileged Access Management systems, anti-phishing email gateways, encryption and cryptography. I work extensively with OpenSSL, Botan, Crypto++, and Bouncy Castle. 𝗥𝗲𝘃𝗲𝗿𝘀𝗲 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 Binary analysis, protocol reverse engineering, and software internals research using IDA, Ghidra, and Frida. 𝗛𝗶𝗴𝗵-𝗙𝗿𝗲𝗾𝘂𝗲𝗻𝗰𝘆 𝗧𝗿𝗮𝗱𝗶𝗻𝗴 I designed and built an HKEX-certified trading system achieving 5μs round-trip latency between receiving market data, decision-making, and sending orders. Market data processing, order management, web API design. 𝗪𝗵𝗮𝘁 𝗜 𝗕𝗿𝗶𝗻𝗴 𝘁𝗼 𝗬𝗼𝘂𝗿 𝗣𝗿𝗼𝗷𝗲𝗰𝘁 ▸ Modern C++23, multithreading, networking, performance optimization ▸ Ability to build from scratch or take over and evolve complex existing codebases ▸ AI-augmented development - I use tools like Claude Code to accelerate routine implementation while maintaining full architectural control and code quality Feel free to message me - I typically respond within a few hours and I'm happy to discuss your project before you commit.

I create optimized 3D models for games, AR/VR, product rendering, and 3D printing. What I do: - Low-poly 3D models for different budgets based on the number of polygons and resolution of textures according to your technical task. I can also search for references myself. I monitor the quality of UV and texel. The main thing is that it will always turn out beautifully. I will always consult with you so that we are both happy with the result :) - High-poly photorealistic 3d models, textures and renders. This can be an interior or exterior, a product rendering to indicate its qualities, or to improve sales through a beautiful product visualization. I can create complex shapes and patterns, I love details and beautiful realistic textures. - Photorealistic Rendering. I deliver high-resolution renders from various angles, meticulously adjusting different types of lighting: studio, lifestyle, and experimental. I always produce a preliminary render to confirm the best angles, shadows, the intricate play of materials, and lighting that enhances the silhouette and shapes. My material expertise ranges from simple to complex—flawless new plastic, light-transmitting glass, weathered wood, and rusted metal ant others. I can create anything! - AR/VR-ready assets. I create optimized 3D models for augmented and virtual reality experiences, including accurate scale, pivot placement, and clean topology. I export assets in USDZ, glTF, FBX, and OBJ, fully compatible with platforms like Reality Composer, Spark AR, and Oculus Quest. I test the models directly on Apple and Oculus devices. My experience also includes 3D projection mapping for architecture in Blender, with material IDs, custom color masks, and EXR output including Cryptomatte passes for advanced compositing and real-time use. 3D printing models. I prepare watertight, error-free models ready for 3D printing. This includes clean mesh structure, correct scale and orientation, and optimization for slicing. Whether it’s a functional object or a highly detailed sculpt, I ensure it’s ready for successful printing, with clear geometry and proper proportions preserved. Work software: Blender, 3ds Max, Substance Painter, Keyshot, Zbrush. ⚙️ Workflow - Regular WIP (work-in-progress) updates for quick feedback and adjustments - Testing models across different tools to ensure compatibility - Deliverables: models, textures, exports, source files 💬 Communication I'm always in touch and share regular WIP updates. My goal is to fully understand your project needs and deliver results that meet or exceed expectations. Experience I have 1.5 years of experience creating animated 3D NFT models for VR/AR environments, focusing on optimization and platform compatibility. I’ve built close-up animation assets with realistic PBR textures and balanced polycount for 3 years, as well as complex interior scenes with curved, futuristic designs. My background includes 5 years of asset development for the game industry, as well as creating custom content for The Sims 4 — including furniture, clothing, and accessories. I’ve also developed Instagram filters featuring 3D elements like masks and glasses. In many projects, I designed models entirely from scratch, combining a strong visual sense with a willingness to experiment when the project called for originality. At the same time, I’m fully comfortable following clear instructions when needed.

I have over 30 years experience in software development, rich project and expertise background. My favourite and the most cherished type of work is plunging into a new promising technology and studying new devices. I had a series of great research projects with Chinese FPGA for a USA customer. Most of my projects implied C/C++ implementations and use of STM32 boards. Also I have a great expertise in Teensy 4.2. board. My best feature as a developer is digging a black hole and setting out with super-damn problems, sleeping on it and finding out how to resolve the things. I am ready to provide high quality services in implementing and realizing clients' ideas for new IoT devices, various hardware projects, and previous "old" projects where a developer left the team and you don't know how to proceed with it. I love to find quick solutions for super-tricky problems, I am genius at it. All my customers are glad to cooperate with me because I never fail them. They are even thinking over finding something extremely difficult for me to sort it out. It's my bread and I am worth every cent, bet you!
