Backend engineer building systems that solve real problems. Started with competitive programming, now shipping production code at Astana Hub.
I engineer software from scratch and optimize what already exists. Currently working on backend services handling 7K+ active users, building everything from WebSocket chat systems to high-performance APIs.
Right now:
- 🏢 Backend Developer at Astana Hub (Kazakhstan's national tech hub)
- 🛠️ Building Finance Tracker - solving my own pain of manual transaction imports
- 📚 Learning system design and distributed architectures
- 🌱 Looking to contribute to open source
Languages I work with:
- Java (my go-to for serious systems)
- Python (when I need speed and simplicity)
- SQL (PostgreSQL mostly)
Tools & Frameworks:
- Spring Boot, Django, FastAPI
- Docker, Redis, MongoDB
- Git/GitHub, JUnit, pytest
Started coding through competitive programming olympiads. Spent years solving algorithmic problems in C++ until I got addicted. That foundation helps me write efficient code and debug complex systems.
Competitive Programming:
- Codeforces Specialist (1700 rating, 500+ problems solved)
- National Olympiad in Informatics: Silver & Bronze medals (Top 12 nationally)
These days I write less CP and more production code, but the problem-solving mindset stuck with me.
Built this because I was tired of manually importing bank transactions. It automatically parses PDF statements and categorizes expenses.
Tech: Java, Spring Boot, PostgreSQL, Redis, Docker Highlights:
- JWT authentication & secure APIs
- 9x faster API responses through caching
- PDF parser for automatic transaction import
- Background job processing
Planning to add a frontend soon and maybe open it up for others with the same problem.
I like seeing "Accepted" on a solution I spent days thinking about. I like building something from nothing and watching it work. I like making slow things fast.
When I'm not coding, I'm probably doing sports or thinking about the next optimization.
Open to: Internship opportunities, interesting side projects, and collaboration on open source.
Write clean code. Make it work. Make it better.
