My name's Sebastian Gębski, I think of myself as an engineering leader (at scale). My career has been hardened in the fire of several IT project- and product-based engagements, starting with start-ups, ending with large banks and insurance companies, where I've proven myself also as a polyglot architect and an effective practitioner of Domain Driven Design. My specialty is building high-performing engineering organizations and shaping modern delivery pipelines - with scalable development processes, lean tooling, and Continuous Delivery principle in mind.

I add value by leveraging my experience and knowledge at scale, but I'm not afraid to put my own hands on code if needed.


Technologies I feel myself most comfortable (and have the most practical experience) with:

  • anything related to .NET (Core), just name your thing …
  • modern data engineering/analytics (both stream-based real-time and OLAP upon DWH/DL)
  • wide spectrum of AWS cloud portfolio services
  • Cloud Native ecosystem
  • Elixir & Phoenix

… but I'm no stranger to other development tech platforms/stacks (incl. Python, Scala, JavaScript, Rust, Golang, etc.).


Catchy acronyms I'm entitled to use (certifications, titles, etc.):

  • MCTS, MCPD, MCSD - bag of Microsoft certifications
  • PMP & PMI-ACP
  • PRINCE2 Practitioner
  • PSM III (Professional Scrum Master III) & Scaled Professional Scrum
  • ITIL v3 Foundation
  • TOGAF 9 Certified
  • AWS Certified Solution Architect - Associate

I've led teams up to 70 people in endeavors that involved hundreds of individuals. I prefer (by far) to do my job the Lean way; kaizen and professional curiosity is what fuels me on daily basis. I'm up to any challenge, as long as there's glory to be earned and it's a step forth, not back (for myself, company, team, customers & users).

I speak on this blog for myself only.
