Full-Stack Consultant Needed for FinTech App Review
Great freelancer to work with. Illia quickly understood the product, reviewed both backend and frontend concerns, and gave clear, practical recommendations. Strong full-stack knowledge across Node.js, NestJS, Next.js, Angular, and TypeScript. Communication was smooth, and the consultation was genuinely useful.

AI Analytics Feature Development for Web App
I needed this done urgently, and Illia jumped in right away. He understood the business logic immediately and suggested smarter ways to implement AI insights. Clean implementation, reliable communication, and a real understanding of how analytics should help users, not overwhelm them. Would definitely work together again.

Looking for Expert SaaS Architecture
Illia fixed our database design, made payments with Stripe way safer, and set up CI/CD. Knows his stuff with big systems, and honestly saved us from some very expensive mistakes. Super glad we found him.

Lead backend developer needed - MVP build for a new startup - Typescript, NodeJS, GraphQL, Postgres
Sednor supplied us with 2 senior full-stack typescript/javascript devs. They both joined our teams, adapted to our internal processes and have been rock solid members.
Sednor and their team are very professional, polite and respectful. They get the job done to a very high quality and go further than just the requirements written in the tickets. They ensure they understand the project and the business and are able to fill in gaps that have been missed by our Tech Lead and PM.
They're smart, pro-active, dependable and independent and I'd definitely hire them again!
