Hire a Senior Fullstack Developer — Meet Lucky

What are you building?

Pick the closest fit — we'll scope from there.

About Lucky

Senior fullstack engineer for hire — Next.js, AI, fintech.

Meet Lucky is the front door to Lucky S Software, the studio of Samed Kahyaoğlu. Tell the agent what you're building and it scopes the work, surfaces the right references from past projects, and quotes a price the moment scope is clear — no discovery call required.

Lucky takes a small number of selective engagements per quarter across four tracks: shipping a production-ready Next.js or TypeScript web app, adding LLM features (chat, RAG, semantic search) to an existing product, untangling and modernizing legacy stacks, and fractional CTO work for fintech and Web3 startups where the wrong technical call costs more than the build.

Every engagement is spec-driven, architecture-first, documented for clean handoff, and monitored in production from day one. See the full services breakdown or email Lucky directly if you'd rather skip the chat.
