Need a reliable developer to quickly debug or build features? I work across Python, C++, Java, Rust, Go, Julia, and Rfrom fixing tricky runtime errors to developing clean, productionready modules with tests and documentation.

What I do

  • Debugging & Bug Fixes: crashes, exceptions, memory issues, logic errors, dependency problems
  • Feature Development: CLI tools, APIs, data pipelines, scripts, automation
  • Performance Optimization: profiling, algorithmic improvements, parallelization where sensible
  • Testing & CI: unit tests (pytest/JUnit/go test), GitHub Actions setup
  • Code Review & Refactor: readability, structure, best practices, maintainability
  • Data/ML scripting (Python/R/Julia): pandas, NumPy, scikitlearn, plotting, notebooks

Tech Im comfortable with

  • Python: Flask/FastAPI, pandas, NumPy, pytest
  • C++: STL, OOP, CMake, basic memory profiling
  • Java: Maven/Gradle, JUnit, Spring basics
  • Rust: cargo, ownership/borrowing, error handling

Why me

  • Clear, reproducible fixes with comments
  • Clean commits and pull requests
  • Friendly communication & ontime delivery

Send me: a brief of the issue/feature, the repo or code files, and how to reproduce. Ill rerespond with a concrete plan and timeline.
