Elixir and Phoenix development
Build a feature, fix a difficult defect or connect your application to another system. Get working software, relevant checks and a handoff your team can use.
Software development and product consulting
Good software starts with deciding what matters.
We help teams decide what to build and carry it through to working software.
We build Elixir and Phoenix applications, improve development workflows, and help teams use coding agents effectively.

How we can help.
Work with Almir Sarajčić through Optimum Tech. He uses coding agents to deliver software and takes responsibility for technical decisions, verification and the final result.
We agree on a concrete outcome, what is included, the checks that show it works and the handoff you need to keep using it.
Development workflows and faster feedback
Shorten feedback loops while keeping useful checks. Improve builds, tests, CI/CD, preview environments and review practices so your team can develop, verify and deliver changes sooner.
Coding-agent workflows
Help your team use coding agents on real features and repairs. Improve the context, review and verification they need, with guidance your team can use again.
