Freelance full-stack software engineer
Hire Me!
I’ve been contributing to projects either as the solo coder or a
technical lead on a small team. I bring value to my clients by helping them chose and implement software that serves their business.
Past projects include:
- saving money by optimizing clients' 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 most projects we used:
- DevOps practices
- Git
- Docker
- Continuous Integration
- Markdown
- Unit tests
Also a powerlifter (-75kg. 145kg squat, 100kg bench-press, 180kg deadlift).

This blog post is actually a draft for a standard operating procedure for my software development and consulting business. I’ve come across the task of writing tests for HTTP APIs for three or four times in the last couple of months. I’ve tried multiple ways of writing automated tests and this is the method I’ve converged on. TypeScript, Jest, and supertest appear to work well together and are sufficient to implement concise tests.

I love good sound. I’ve been suffering with my poor bookshelf speakers for a while now. They simply don’t produce enough output at the bottom end of the spectrum. I don’t want to annoy neighbors. But I do want to feel the rhythm. I went to a Hi-Fi store to listen to a couple of speakers. I flirted with a pair of Polk Signature Series S55 floor standing speakers. But I didn’t want to open my wallet just yet. I remembered there is an old Genious SW HF 5.1 5000 system somewhere in the basement.
But they were broken. The subwoofer is humming loudly even with no input. Armed with all the electronics knowledge from YouTube I gave myself a shot at repairing this.

You are reading a success story of avoiding premature optimization. I had to design an API for a service that receives some geographical data and returns the same data with additional information for each point of interest.
