One engineer.
Whole product.
I'm a one-person product team — design, ship and scale full-stack software, with AI integrations woven in where they actually earn their place.
About
I treat shipping a product as a single craft — not a relay between five specialists.
Across a decade of work I've handled the parts most teams split up: React / Angular / Next.js on the front, NestJS / Express / Python on the back, Postgres / MongoDB / MySQL underneath, and the Azure / AWS / GCP scaffolding around it.
Lately, the most interesting work is in AI integrations — figuring out where an LLM, an embedding model, or an agent actually moves the needle in a product, then building it so it doesn't fall over in production.
I take on the unfamiliar on purpose. New stack, new domain, hard problem — that's usually the bit I want. The way I keep getting better is by deliberately picking up the thing I haven't built before.

Despite this, he quickly understood how the product worked, cleaned up the codebase, and fixed production issues. He handled back-end, front-end, AI, prompts, SEO and infrastructure entirely autonomously. Fast, meticulous, highly reliable. A dependable, versatile, fully committed developer. I recommend him without hesitation.
I had the pleasure of working with Bogdan on a strategic assignment. He was extremely efficient, gave very good advice and was able to intervene quickly, even proposing solutions that went beyond the initial brief. His ability to step back and correct problems quickly made all the difference. I highly recommend his expertise!
Bogdan demonstrated a highly effective ability to learn a technology stack quickly and build out a viable prototype. Communications of scope, progress, and findings were detailed and enabled working at a distance and asynchronously.
