Why Work With Code Sense Studio
Code Sense Studio runs shipped product, not just consulting. Ombar (live SaaS for dive shops) and Tendril (in build) are the studio's own work — same hands that take client engagements.
Code Sense Studios OÜ is the legal entity. One senior engineer on delivery — no junior swap, no white-labelled sub-contractor. You talk to the person who writes the code.
AI-native workflow as a real productivity unlock. Claude and Codex heavily, MCP servers for tooling — it's how the studio runs at the throughput of a small team.
Range, not point. €40–80/hr depending on stack, scope, and engagement length — fixed-bid for audits and short sprints. Scoped to the work.
What People Say
“Joao is one of those rare developers who is as technically gifted as he is great to be around. On our Crop Controller project, he was lightning-fast and consistently ahead of the game. I quickly learned I could trust him with total autonomy over UI decisions, and he never let me down. He has a real knack for looking at a requirement and spotting how it might need to evolve, ensuring his solutions are truly built to last. More than just his skills, though, it's Joao's heart and hustle that make the difference. He's incredibly committed, has a stellar work ethic, and his happy, team-first attitude made every sprint better. Any team would be lucky to have him.”
