Arpit S.

I’m a Senior Python & AI Engineer with 9+ years of experience building production-ready backend systems, AI-powered applications, automation workflows, and SaaS products.
I help companies turn complex business processes into reliable Python applications, APIs, AI workflows, and scalable cloud solutions.

What I can help you build:

• Python Backend: Django, FastAPI, Flask, REST APIs, microservices
• AI & LLM Applications: OpenAI, Anthropic, Gemini, RAG, agents, tool calling, structured outputs
• AI Automation: n8n, Make, Zapier, Python automation, webhooks, API orchestration
• Data & Documents: Data processing, ETL, document workflows, extraction and validation
• Full-Stack Applications: React, Next.js, TypeScript + Python backends
• Databases: PostgreSQL, MySQL, MongoDB, Redis, Supabase
• Cloud & Deployment: AWS, Docker, Kubernetes, CI/CD
• Integrations: Third-party APIs, SaaS platforms, CRMs, payment systems and business workflows

AI / Automation Experience:
I’ve built AI-powered workflows involving LLM APIs, RAG, document processing, information retrieval, structured outputs and business-process automation.

I also use Cursor and GitHub Copilot to accelerate development. I treat AI-generated code as a starting point not as something to blindly ship. Architecture, security, database changes, API contracts, edge cases and production logic are always reviewed and tested manually.
