Project details

I build production-grade backends using FastAPI or Django — not prototype code, but structured, documented systems you can hand off to another developer or deploy on day one.
What this covers: RESTful API design, PostgreSQL database modeling with SQLAlchemy or Django ORM, async background job processing with Celery and Redis (file handling, notifications, scheduled tasks), OAuth2 or token-based authentication, and AWS S3 file storage integration.
The process starts with a short review of your requirements before any code is written. Once the plan is confirmed, you get clean Git-versioned code with a README, endpoint documentation, and a brief handoff note explaining how the system is organized.
Best suited for: MVPs that need a real backend, internal tools being upgraded from a prototype, and teams that need backend infrastructure in place before a frontend developer starts.

Your backend should help your product grow, not become the reason it slows down. Whether you are launching a new SaaS platform, improving an existing application, integrating third-party services, or adding AI capabilities, I build backend systems that are reliable, scalable, and easy to maintain.

I am a Python Backend Developer with experience building production-ready applications using Python, FastAPI, Django, PostgreSQL, Redis, Celery, REST APIs, and cloud-based infrastructure. I work with startups, product companies, and agencies to develop clean backend architectures, optimize existing systems, and deliver solutions that continue to perform as products evolve.

My work goes beyond writing code. I focus on understanding the business problem first, then designing solutions that are maintainable, secure, and built for long-term growth.

What I can help you with

• Python backend development using FastAPI and Django
• REST API design, development, and integration
• PostgreSQL database design and optimization
• Authentication, authorization, and role-based access control
• Background jobs with Celery and Redis
• Payment gateway and third-party API integrations
• AI and LLM integrations using OpenAI, Anthropic Claude, Gemini, and other modern AI services
• Workflow automation and backend services
• Existing application maintenance, debugging, performance optimization, and feature development
• Backend architecture for SaaS platforms

Projects I have worked on include

• Building scalable backend systems for SaaS products
• Developing secure REST APIs consumed by web and mobile applications
• Integrating payment providers, CRMs, and external business platforms
• AI-powered applications using OpenAI and modern LLM APIs
• Automation platforms connecting multiple business systems
• Backend modernization and migration of legacy applications
• Performance optimization for production systems handling large datasets and concurrent users

My development approach

I believe clean architecture is more valuable than quick fixes. I write modular, maintainable code that other developers can understand and extend. Before implementing any solution, I focus on understanding the product, existing architecture, and long-term business goals to avoid creating technical debt.

I also use modern AI-assisted development tools, including Claude Code, where they genuinely improve development speed, debugging, refactoring, and documentation. Every implementation is reviewed, tested, and refined before delivery to ensure production-quality code rather than AI-generated shortcuts.

Technologies

• Backend: Python, FastAPI, Django, Flask
• Databases: PostgreSQL, MySQL, Redis
• APIs: REST APIs, GraphQL, Webhooks, OAuth 2.0
• Cloud & DevOps: AWS, Docker, Git, CI/CD
• AI: OpenAI, Anthropic Claude, Gemini, LangChain, LLM Integrations
• Automation: n8n, Zapier, Make, API Automation

Why clients enjoy working with me

• Clear and proactive communication
• Clean, well-structured, maintainable code
• Reliable delivery and realistic timelines
• Strong focus on scalability and long-term maintainability
• Comfortable working independently or as part of an existing engineering team

Whether you need a backend built from scratch, new APIs, AI integration, performance improvements, or ongoing development support, I'd be happy to discuss your project and recommend the most practical approach before we begin.
