I solve low-level problems. I’ve worked on Chromium source, custom native compilers, and high-performance systems. My background includes 5 years as an SDET and DevOps, meaning I deliver production-ready code backed by automated testing and stable CI/CD pipelines. Key Projects: - Antidetect Browser: Optimized Chromium internals and process models to bypass detection bottlenecks. - CEF Integration: Engineered a high-speed bridge for the Elastic language to manage native/frontend execution flow. - Isometric Engine: Built a 3D-physics engine in Raylib with custom binary serialization. - Networking: Implemented low-latency state syncing via WebSockets. The Deal: I provide technical foresight. If your architecture creates debt, I’ll propose a sustainable path.

Hello! I am an electrical engineer with over 5 years of experience in embedded systems and control engineering. If you need guidance on the best way to frame your electronics project, someone to do your embedded software (firmware) coding, or if you need help tuning a controller, I'd be happy to work with you. My experience: • Embedded software and hardware architecture • Control system design and implementation • Firmware development in C/C++, bare or RTOS • Python scripting • IoT protocols: LTE, MQTT, TCP/IP, HTTP, CoAP, BLE, GNSS • Communication protocols CAN, SPI, UART, I2C • Various boards and MCUs: STM32, TI, AVR, nRF, ESP, Arduino, RPi

System engineer specializing in deep diagnostics, stabilization, and deconstruction of failing distributed systems. Strong in API/Graph, network and protocol analysis, and resolving integration failures across M365/Power Platform services. Skilled at identifying root causes, uncovering anomalies and documenting clear, evidence-based conclusions

Fast-learning, creative, team-oriented person experienced in software development and testing who would quickly integrate into your work organization and could efficiently pursue tasks entrusted to me. I am an engineer eager to solve complex and peculiar problems and then finding simple words to explain to others.

I've spent the last decade building and scaling backend systems — mostly PHP/MySQL, but also Node.js, Go, and Python when the job calls for it. Most recently I spent 6 years as Lead Developer at Timewise — an appointment booking and POS platform for salons, gyms, studios, and other service businesses. I was responsible for backend architecture, API development, AWS infrastructure, and DevOps. I built and maintained the core systems that power scheduling, payments, staff management, and reporting. Outside of that, I've built everything from real-time trading systems with WebSocket feeds and live order execution, to full-stack SaaS apps, booking platforms, merchant dashboards, and analytics APIs. What I bring to the table: - Performance diagnosis and optimization — I work by collecting metrics across the request path, isolating the slow part, fixing it, and repeating until it's fast - Database expertise — query optimization, indexing strategies, connection management, schema design (MySQL primarily) - AWS infrastructure — EC2, RDS, load balancers, autoscaling, monitoring, cost management - DevOps — Docker, Kubernetes, CI/CD pipelines, automated deployments - API development — REST and GraphQL, built to handle load - Full-stack when needed — React, TypeScript, modern frontend tooling I communicate clearly and get to the point. I'm used to owning systems end-to-end — I don't need hand-holding to get things done. Tech: PHP, MySQL, Node.js, TypeScript, Go, Python, AWS, Docker, Kubernetes, Redis, GraphQL
