Stephen Kariithi

I am a Backend-Focused Software Engineering student specializing in building high-performance, scalable, and production-ready systems using Go (Golang) and Python (Flask/Django).
I help individuals, startups, and businesses turn ideas into efficient backend systems and APIs that are reliable, fast, and easy to scale.
Here’s what I can do for you:
• Design and develop RESTful APIs using Go or Python (Flask/Django)
• Build real-time systems using WebSockets for live updates (e.g. dashboards, chat apps, stock tickers)
• Integrate third-party APIs (payments, weather, data services, etc.)
• Develop backend logic and database structures (SQLite, MySQL, SQLAlchemy)
• Create CLI tools for automation and data processing
• Build systems that generate PDFs from dynamic data
• Fix bugs, improve performance, and optimize existing backend systems
• Connect frontend applications (React or vanilla JS) to backend services
What makes me different:
• Strong focus on performance and low-latency systems (Go standard library)
• Experience with concurrent systems and real-time data streaming
• Clean, structured, and maintainable code
• Ability to deliver working solutions under tight deadlines
• Business-oriented mindset (I build solutions that solve real problems)

Recent projects include:

• A System Health API that exposes real-time system metrics
• A real-time stock ticker using WebSockets and Go concurrency
• A job application tracker with full CRUD functionality (live deployed)
• A weather CLI tool integrating external APIs
• A PDF document generator service via REST API
I am reliable, detail-oriented, and focused on delivering practical solutions that work.
