How I work
I turn an open-ended idea into requirements, constraints, and a practical first outcome.
I make architecture and scope decisions that fit the product instead of adding complexity for its own sake.
I use tools such as Codex and Claude for implementation, then guide iteration and verify the result.
I check the important paths, refine the details, and prepare a result that can be used and improved.
About
I’m Andrei Tiumentsev, an AI-first developer and product builder based in Israel.
I work across the product cycle: clarifying what needs to exist, choosing how to build it, managing AI-assisted implementation, and staying with the work through testing and delivery.
I’m studying Digital Marketing at Ariel University, with expected graduation in 2027. That perspective helps me connect product decisions with the people a product needs to reach.
