My 14+ years in project management means you get senior development combined with predictable delivery 𝗕𝗮𝗰𝗸𝗲𝗻𝗱 & 𝗦𝗮𝗮𝗦 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 • SaaS & B2B backends: multi-tenant architecture, tenant isolation, row-level security, role-based access control, OAuth / authentication, audit logging • eCommerce & marketplace systems: product catalogues, order management, inventory, payment flows, webhook event handling • Payment integrations: Stripe Connect (Standard & Express), subscription billing, split-payment flows, async webhook handling • APIs: Django REST Framework, FastAPI, RESTful API design, REST API, third-party integrations (Stripe, Twilio, OpenAI, Gmail API) • Async systems: AsyncIO, Celery, Redis, background workers, job scheduling, distributed event processing • Data processing: ETL pipelines, web scraping, PDF/document parsing, bulk CSV ingestion, data workflows • Cloud & DevOps: AWS, GCP, Azure, Docker, CI/CD (GitHub Actions, GitLab CI), structured logging, error monitoring 𝗔𝗜 & 𝗟𝗟𝗠-𝗽𝗼𝘄𝗲𝗿𝗲𝗱 𝘀𝘆𝘀𝘁𝗲𝗺𝘀 • Intelligent assistants and AI-powered features using LangChain, OpenAI API, and RAG pipelines • Vector search and semantic retrieval: FAISS, Pinecone, vector database integrations • LLM workflows integrated into structured backend APIs with production stability • System architecture for AI-enabled products - reliable, scalable, maintainable 𝗦𝗲𝗿𝘃𝗶𝗰𝗲𝘀 • SaaS MVP development - system architecture through production-ready deployment • Multi-tenant platform builds - data isolation, tenant management, subscription tiers • eCommerce backend development - marketplace logic, inventory, fulfilment integrations • Payment system integration - Stripe Connect, subscription billing, webhook pipelines • AI / LLM integration - LangChain, RAG pipelines, vector search, OpenAI API • Backend architecture audits and implementation roadmaps • PostgreSQL schema design and query optimisation • Django to FastAPI migration planning • AWS / GCP cloud architecture review and cost optimisation • CI/CD pipeline setup - production-ready from day one My background is senior Python backend development - 8 years of building SaaS platforms, B2B product backends, and eCommerce infrastructure using FastAPI, Django REST Framework, AsyncIO, Celery, PostgreSQL, Redis, AWS, and GCP. I focus on projects where architecture matters from day one - multi-tenant SaaS platforms, marketplace backends, B2B portals, and eCommerce systems where scale and reliability are not optional. Beyond core backend work, I integrate LangChain, RAG pipelines, and OpenAI API into production systems - built to be stable, maintainable, and part of a real product rather than a prototype. If you are building a SaaS platform, a marketplace, a B2B portal, or a payment-integrated product and need a senior Python backend developer who manages the delivery end to end - I would like to hear about it.
