Complete Solution is a senior product engineering agency in Trnava, Slovakia. We build, ship, and scale software products for clients across Europe and the US - from architecture through launch and support.
WHAT WE DO
We work with founders and product teams who need senior engineers from day one - not juniors hidden behind a sales pitch. Every engineer on our team has 5+ years of production experience.
We ship across four engagement models:
- Build a Product - End-to-end product development. One team owns strategy, design, frontend, backend, deployment, and support. From MVP to scale.
- Add AI to Your Workflow - LLM integrations, RAG pipelines, document processing, and agentic workflows. We've shipped AI products serving tens of thousands of paying users.
- Extend Your Team - Senior engineers embedded in your standups, following your standards, shipping like they've been there for years.
- Hire Through Us - IT recruiting backed by the same vetting process we use internally.
THE SIX-DISCIPLINE SYSTEM
Every product runs through the same process: Strategy -> Design -> Development -> Test -> Launch -> Support. Each side has a dedicated senior owner, clear deliverables, and defined exit criteria.
