Python Django full stack developer specializing in SaaS MVPs and fintech platforms - 14 production-ready SaaS MVPs delivered in 4 to 6 weeks across fintech, expense management, and AI-powered web applications. I build scalable web applications that go from idea to working product fast: Django REST databases, and OpenAI API integrations. My focus is on clean architecture that's easy to maintain and extend - not overengineered, not held together with duct tape. My core work covers full stack SaaS development from MVP to production, multi-tenant SaaS architecture, Django and FastAPI backends with role-based access and authentication, subscription and payment integration, React and Node.js frontends, AI integrations using OpenAI API and Google Document AI, and cloud infrastructure on AWS with Docker. How I work: I start by mapping exact requirements and proposing a tech stack that fits your timeline and budget. I move fast, communicate clearly, and deliver working software - not just code. Every project includes documentation and handover so your team can take ownership after launch. Recent work: Built an AI-powered check scanning feature for Spendbase, a B2B expense management SaaS platform based in Delaware. Using Python and Google Document AI, we automated data extraction from paper checks and integrated it into their existing expense workflow - delivered on a tight deadline with full documentation and zero disruption to the live platform. If you need a production-ready SaaS MVP, a Django backend with AI integration, or a reliable Python full stack partner for the long term, let's talk.

I work as a Full Stack Developer and Python Developer across both frontend and backend systems, designing products from scratch, improving legacy platforms, integrating APIs, and scaling architecture for long-term growth. In backend-heavy systems, I act primarily as a Python Developer and Node.js Developer, while on client-facing interfaces I operate as a React Developer and JavaScript Developer. As a Full Stack Developer and Python Developer, I worked in startup environments, Big Tech companies, and enterprise teams, collaborating in international English-speaking settings. I followed structured workflows using Jira, Kanban boards, sprint planning, and code review processes where a Node.js Developer and Python Developer often share backend responsibilities depending on service boundaries. I have 10+ years of experience as a Python Developer, working deeply with Python for backend systems, automation, and data pipelines. In parallel, I have 7+ years of experience as a Node.js Developer building scalable APIs and real-time services. On the frontend side, I have 5+ years of experience as a React Developer and JavaScript Developer building modern UI systems. During my career as a Full Stack Developer and Python Developer, I’ve implemented 200+ REST APIs and integrations across payment systems, messaging APIs, and AI services. Many of these were split between Node.js Developer services for real-time workloads and Python Developer services for data processing and ML pipelines. Primary stack: Python (FastAPI, Django, DRF), Node.js (Express, NestJS), TypeScript, JavaScript Developer, React Developer, Next.js, PostgreSQL, MongoDB, Redis, Supabase. In practice, this means I switch between Python Developer roles for backend intelligence layers and Node.js Developer roles for event-driven systems and APIs, while React Developer and JavaScript Developer responsibilities cover frontend architecture and UI delivery. Over the last 10+ years as a Full Stack Developer and Python Developer, I’ve built SaaS products, automation systems, AI platforms, and analytics engines. These systems typically combine Python Developer services for processing and Node.js Developer services for orchestration, with React Developer dashboards and JavaScript Developer frontends. My main focus today as a Python Developer and Full Stack Developer is AI engineering, backend architecture, and scalable systems. I design RAG pipelines, LLM integrations, and automation workflows where Python Developer components handle computation-heavy logic and Node.js Developer services manage API orchestration. I have experience as a Python Developer running asynchronous workers processing 10K+ background jobs daily, and as a Node.js Developer building event-driven microservices for high-throughput systems. On the frontend, as a React Developer and JavaScript Developer, I build dashboards, admin panels, and product interfaces. As a Full Stack Developer and Python Developer, I take ownership of both backend and frontend architecture, including APIs, databases, authentication systems, and performance-critical applications. In most systems I’ve delivered, the backend is split between Python Developer services and Node.js Developer services, while the frontend is handled with React Developer and JavaScript Developer stacks. One thing that separates me is that I understand both production engineering and AI-generated code risks. As a Python Developer and Node.js Developer, I regularly review and refactor AI-generated backend logic to ensure stability, while as a React Developer and JavaScript Developer I ensure UI logic stays maintainable and scalable. I don’t just generate code quickly. As a Full Stack Developer, Python Developer, Node.js Developer, React Developer, and JavaScript Developer, I build systems that remain stable under scale and long-term maintenance pressure. As a Senior Full Stack Developer and Python Developer, I care about clean architecture, fast delivery, and systems that don’t collapse under growth.
