I’m Denis Shepelev — a mechanical and software engineer. I care about code that is readable, testable, and easy to change, and I apply the same principles to mechanical designs: clarity, repeatability, and adaptability.

What I do

• Systems engineering at the software–mechanics boundary — I design and build integrated solutions where code drives real-world mechanisms (robots, automation, energy systems).
• Software engineering — designing reliable, modular systems across the stack, with an emphasis on maintainability and testability.
• Programming languages — I work primarily in TypeScript, Python, and C++, and I write about patterns and pitfalls in these ecosystems.
• Developer tooling & libraries — building tools that make other engineers faster and reduce integration friction.
• Mechanical design & system integration — developing equipment, machines, and automation frameworks, with attention to manufacturability, modularity, and lifecycle adaptability.

Principles

• Prefer clarity over cleverness—in code and in mechanical schematics.
• Optimize for the next reader (or maintainer) of the code or design.
• Document decisions, not just interfaces: I capture why a choice was made, especially when it affects both software and hardware behavior.
• Design for iteration: systems should be easy to evolve as requirements change.
