Full Product Build - from zero to production
A hands-on senior profile to build, stabilize and transfer.
Who it helps
Founder or CTO who needs someone able to decide, build and document without multiplying intermediaries.
The problem
The risk is not only writing code. It is choosing the wrong architecture too early, under-testing, deploying poorly or creating a system the team cannot take over.
How I approach it
- 1Product scoping: priority use cases, success criteria, iterative roadmap.
- 2Architecture choices based on real constraints: Event-Driven, CQRS/DDD, Fusion RPC, multi-tenant and more.
- 3Full-stack implementation: .NET backend, frontend, mobile, database and third-party integrations.
- 4GenAI or ML only when it brings measurable value.
- 5QA: unit, integration and e2e tests on critical paths.
- 6DevOps: CI/CD, Docker, staging, production and OpenTelemetry.
- 7Documentation and handover so the next team remains autonomous.
What you leave with
- A product in production, not only a POC.
- Documented architecture, tests and CI/CD in place.
- Decision records so the team understands why it is built that way.
- Team handover included, without dependency on my presence after delivery.
Concrete proof
Recent selection: OneRP, SaleCast, Matchr, PromptVault, MyRoadTrip and Poisson Engine - client missions, personal products and R&D delivered around real constraints.
