I'm a Go backend engineer specializing in distributed systems and production-grade infrastructure. I build systems that scale, fail gracefully, and are maintainable by teams.
My journey spans full-stack development, but I've found my passion in backend architecture where concurrency, reliability, and performance are non-negotiable. I thrive in large codebases where understanding system invariants and failure modes is critical.

},
CoreStrengths: []string{
"Concurrent & Async Systems (Goroutines, Channels)",
"RESTful & gRPC API Design",
"Database Optimization & Caching Strategies",

},
CurrentMission: "Contributing to production OSS & mastering distributed systems patterns",
Philosophy: "Write code that's correct first, then make it fast. Test what matters.",
}
}

I contribute to production-scale open-source projects where reliability and performance are critical. My approach is grounded in understanding systems deeply before making changes.

- Worker pools and pipeline patterns
- Race condition detection and prevention
- CPU and memory profiling (pprof)
API Development:
- RESTful services with
net/http, Gin, Echo - gRPC services with Protocol Buffers
- GraphQL with gqlgen
- Middleware patterns (auth, logging, rate limiting)
- OpenAPI/Swagger documentation
Data & Storage:

Read production code to understand real-world patterns and trade-offs |
Use tracing, profiling, and logging to understand system behavior |
Write comprehensive tests that prevent regressions |
"Premature optimization is the root of all evil, but premature pessimization is the mother of poor performance."
I focus on writing correct, maintainable code first, then profile and optimize where it actually matters.
Guiding Principles:
- ✅ Make it work → Make it right → Make it fast
- 🧪 Tests are not optional; they're part of the product
- 📖 Code is read 10x more than it's written
- 🤝 Communicate assumptions and trade-offs clearly
- 🔄 Small, incremental changes compound over time

I believe in learning in public and documenting my journey. Here are topics I write about:
|
🚀 Go Best Practices Patterns I've learned from production systems |
🏗️ System Design Breaking down complex distributed systems |
🐛 Debugging Stories Real-world bug investigations and fixes |
I'm always interested in discussing:
- Go backend architecture and patterns
- Distributed systems challenges
- Open source contribution strategies
- Career growth in backend engineering
When I'm not coding: I'm probably reading source code, debugging distributed systems, or exploring new Go libraries. I find joy in understanding why systems work the way they do, not just how to use them.
