Oleg Gavrilov

Founding Engineer. Full-Stack Developer.

Remote

Rust, Go, PHP, Python, and TypeScript — from technical documentation and domain decomposition to architecture, hands-on development, and production release. Ownership of a substantial technical scope rather than isolated development tasks.

Scope

Substantial technical scope

Understanding the domain, making architectural decisions, implementing the system, and delivering a complete working result to production — not isolated development tasks.

Production focus

Testing, observability, deployment, release automation, and continued system evolution after launch.

Complementary tooling

Rust, Go, PHP, Python, and TypeScript serve as complementary tools rather than rigid technology boundaries. The implementation approach is selected according to delivery speed, correctness, performance, operational complexity, and long-term maintainability.
