Efficient Code. Real Effect.

I’m Piotr Jamiński - Lead .NET & Azure Developer. I build future-ready cloud systems where architecture, automation, and craftsmanship drive real business outcomes.

I believe great software is more than code - it’s about impact. Let’s build it together.

About

What I do

I design and build cloud-native systems that stay maintainable, scalable, and observable for years. My focus is on creating architectures that evolve gracefully, enabling teams to move fast without losing control. From event-driven microservices to resilient messaging and CI/CD automation - I help transform ideas into durable and measurable solutions.

Beyond the technical layer, I bring a leadership mindset - mentoring developers, shaping better code review culture, and aligning engineering with business outcomes. My work combines architectural clarity, automation, and craftsmanship.

My approach

  • Futuristic - vision-driven and forward-thinking.
  • Maximizer - pushing good to great in people and systems.
  • Adaptability - staying effective amid change.
  • Responsibility - delivering on promises and commitments.
  • Ideation - generating creative and practical solutions.

Tech toolkit

  • .NET 8 / C# - DDD, CQRS, async messaging, clean architecture
  • Azure - Functions, Service Bus, API Management, Cosmos DB
  • CI/CD - Azure DevOps pipelines, quality gates, test automation
  • Databases & ORMs - SQL Server, MySQL · EF Core, Dapper
  • Testing - unit & integration tests, Testcontainers, mocking

Why "Effikoy"?

In Esperanto, efiko means "effect" (plural: efikoj - outcomes). The brand stands for efficiency and real results: delivering impact, not just implementation.
