I’m a backend API developer specializing in FastAPI (Python) and Spring Boot (Java) for web and mobile applications.

I help startups, agencies and product teams build, fix and extend backend systems whether that means creating new REST APIs from scratch or debugging and improving existing code that has become slow, unstable or hard to maintain.

What I do:

- REST API development using FastAPI or Spring Boot
Clean, well-structured endpoints with proper request/response models and authentication.

- Fixing broken or slow backends
Debugging API errors, crashes, misconfigurations, and performance issues in existing systems.

- PostgreSQL database design & improvements
Schema design, migrations, indexing, and query optimization for real-world usage.

- Improving existing codebases
Refactoring messy or partially implemented backend code to make it easier to understand and extend.

- Backend support for frontend teams
Making sure APIs are consistent, documented, and easy to consume by web or mobile clients.

Technologies I work with:

- Python, FastAPI, SQLAlchemy

- Java, Spring Boot, Spring Data JPA

- PostgreSQL (schema design, migrations, indexing)

- REST / JSON APIs

- JWT-based authentication

- Docker

- CI workflows and environment setup


How I work:

- We agree on clear scope and expectations before coding starts

- I break work into small, reviewable milestones

- I write clean, readable code and explain decisions when needed

- I communicate clearly and give regular progress updates

I’m available for API development, backend debugging, database work and short focused tasks where you need a reliable developer to move things forward without unnecessary complexity.

If you need a backend that works predictably and is easy to build on, feel free to invite me. I’ll review your requirements and suggest a clear next step.
