Full stack developer / SaaS developer with AI developer skills needed for Upgrades | React Python
Thanks again, Ilya — as always, he jumped in and helped with upgrades to my SaaS. He’s solid both as an AI Solution & SaaS Architect / SaaS developer — so you get the big-picture decisions and the actual delivery in one place.
What I really like is that he’s the same person acting as a Web developer and an AI developer, so nothing gets stuck between “the web guy” and “the AI guy”. End result: fewer meetings, more shipping.
At this point I just treat Ilya as an AI Full Stack developer (in the best possible way) — a proper Senior Full-Stack developer who can cover the whole loop for an AI-driven SaaS. Cheers, I’ll definitely keep coming back for the next round of upgrades.

Structured Proposal and Alternates
Ilya is exceptional. What stands out is not just the quality of his work, but for the way he works. He brings a combination of thoughtfulness, structure, sharp thinking, and genuine care to the process. He's organized and very intentional in how he approaches a problem. His communication was consistently clear, professional, transparent and he is easy to work with. I was really impressed by the care, depth, and sound judgment he brought to my proposal. The entire experience felt considered from start to finish. He contributed real value, and I would gladly recommend him.

AI SaaS Development
Thanks to Ilya and his team I am now in a position to take my AI driven SaaS platform to market here in the US. Ilya led the work as the AI solutions architect and AI developer, taking ownership of the overall architecture and delivery.
He helped implement the core product on a React + AWS stack, including a solid data/auth foundation and clean integrations for our AI layer (LLM + RAG). We shipped the first production-ready versions of our natural language processing LLM chat agent (RAG-based) and our machine learning LLM engine used to ingest millions of datasets in realtime. Ilya was proactive about edge cases, data/compliance considerations, and keeping everything structured for our Phase 2 expansion.
On the product side, he collaborated closely as a full stack developer on the React UI and helped shape the UI/UX so it feels like a modern AI SaaS product, not a typical insurance funnel/workflow. Overall, he delivered as a full-stack AI SaaS developer — balancing product, engineering, and AI work without losing speed or quality. Communication was direct and reliable, progress was clear week to week, and he consistently thought in terms of product outcomes — not just writing code.
As a founder Ilya was exactly the kind of engineering partner I was looking for. After scoping out the project and building out a roadmap he went straight to work. Ilya did not need any hand holding and is able to develop applications built for scale. Highly recommend Ilya.
We’re continuing to build and scale this platform and I will certainly work with Ilya again.

Ilya makes things happen, he may not always get it right the first time but he always holds himself accountable to getting it done. Love working with him and will do it again.

AI-Powered Crypto Alpha Scoring System (MVP)
Thanks to Ilya for his work as an ML AI developer and Python backend developer on the MVP. He designed and implemented a scalable FastAPI + PostgreSQL + Redis backend, integrated DEXTools / DEXScreener data, and built the NLP / LLM (GPT-4, Grok, FinBERT) sentiment and Alpha Score pipeline for new tokens, including REST APIs and an admin panel. If we continue to extend this crypto intelligence platform, I’ll be happy to work with him again.
