gladecki.pl work with me

Work with me

I'm travelling. Greece right now, but this changes fast. Open to remote work or relocation.

What you can buy

Build the system · 3–6 months, monthly. Elixir/Phoenix backend, concurrent pipelines that hold their shape under load, database-backed job queues, LiveView UI, tests you can trust. You talk to the person who writes the code.

Harden what exists · 2 weeks. Queues, workers, transactions, locks, observability: the parts that break at 3am.

Put AI where it earns its place · 2–4 weeks, fixed scope, fixed price. You have a prototype, a half-built RAG pipeline, or a chatbot that answers wrong. I audit retrieval and ingestion, build the evaluation harness you're missing, and leave you with a pipeline you can measure and ship.

I don't take frontend-only tickets, on-site-only roles, or spec work before a contract.

How it starts

  1. You write three lines: what you're building, where it hurts, what has to change.
  2. A 30-minute call. I tell you whether I'm the right person, and say no if I'm not.
  3. A written scope: what changes, in what order, by when, for how much.
  4. I start. Progress arrives as commits.

When we should talk

  • You need a senior engineer who owns the backend all the way to deployment.
  • Your Elixir/Phoenix product has to stay fast and correct as load grows.
  • Queues, workers or transactions lose work, and you want that fixed for good.
  • You're adding LLMs or RAG and want it built on a system that holds.
