Meet Leo·Source

Engineering is
a team sport.

Independent minds. A shared standard. One team that takes your product as seriously as you do.

Remote-first · AI-native · Self-organized

What we believe

Ownership makes the difference.

Leo·Source is a Ukrainian, remote-first team. Our developers are exclusively Ukrainian, supported by Ukrainian QA engineers and an office manager. We build JavaScript and TypeScript products with React, Angular, Next.js and Node.js, supported by expertise in PHP, databases and cloud infrastructure.

We take responsibility for architecture, implementation, testing and delivery. You work directly with the engineers making decisions, with a lead engineer owning scope and timelines instead of a separate project manager.

We use AI to support research, implementation and testing. Human judgment, code review and testing remain at the heart of every release. Clear communication and documented decisions keep collaboration moving across time zones.

From priorities to a clear delivery plan.

We start by understanding your users, business priorities and existing codebase. Together, we define the scope, technical constraints and acceptance criteria before implementation begins.

During delivery, we make progress visible through working software, code reviews and documented decisions. We raise risks early, explain tradeoffs and keep product priorities connected to technical choices.

Release preparation includes testing, deployment planning and a clear handoff. For ongoing collaboration, we agree on communication channels, time-zone overlap and support coverage.
