I’ve been contributing to projects either as the solo coder or a technical lead on a small team. I bring value to the companies I work with by helping them choose and implement software that serves their business.

Past projects include:

• saving money by optimizing companies’ cloud setup
• managing full software lifecycle, including planning, coding and deployment on cloud (AWS) or on-premises (Docker, VMs, bare metal)
• video: transcoding and delivery of a video archive to web browsers and live streaming with HLS and WebRTC.
• interactive 3D visualization of technical measurements with contextual information (tech stack: WebGL, Three.js, RxJS)
• 2D charts with various twists, including data transfers and rendering with varying levels of detail
• UIs with synchronized maps, video, and charts
• performance optimization by profiling and, if required, rewriting specific parts in C++
• complex Excel reports optimized for printing (language: C#)

Across projects I worked with:

• AWS (Bedrock, Lambda, ECS, EC2, S3, CloudFront, CloudFormation), Terraform, CDK
• AI-assisted development (OpenSpec, SpecKit, Cursor, Claude Code)
• Products incorporating AI (direct LLM calls, retrieval augmented generation - RAG, guardrails)
• React, Angular, design systems
• PHP (Symfony), TypeScript, Node.js, Golang, ORMs (Doctrine), DI/IaC, WebSockets, SSE
• PostgreSQL, DynamoDB, MongoDB
• Video streaming: HLS, WebRTC
• TDD, BDD, version control, SCRUM

Hobbies:

• powerlifting (145kg squat, 100kg bench-press, 180kg deadlift in -75kg BW category)
• climbing (7c sport climb, 7A boulder)
