Senior backend engineer specializing in Python — I build, scale, and own the systems that products run on. If you need a backend that holds up in production — clean APIs, solid architecture, and AI/LLM features that actually work — that's what I do. I'm a Top Rated Plus engineer with 6,200+ hours on Upwork, a 100% Job Success Score, and $90K+ earned, most of it from long-term engagements where clients trusted me to own their backend end to end. A few things clients consistently hire me for: ✅ Backend architecture & APIs from scratch I design and build production systems in Python — Django, FastAPI, and Flask — with REST APIs, relational and NoSQL data models, and clean, documented, testable code. I've led the backend of a live fintech platform (Medius AI) serving real banks and NBFCs in India. ✅ AI/LLM integration I bring AI into real products — OpenAI and other LLMs, prompt engineering, transcription (Whisper), and AI-driven workflows — not as a demo, but shipped and running. I've also worked as a senior Python code reviewer on LLM training data (RLHF / model-alignment workflows). ✅ Scaling & fixing existing systems I take over messy or half-finished codebases, stabilize them, and get them deployed and reliable — including taking sole backend ownership of an existing AI behavioral-health platform (Meomind). ✅ My core stack: Python · Django · FastAPI · Flask · REST APIs · PostgreSQL · MySQL · MongoDB · AWS · Docker · Celery · Redis. I'm comfortable across the full backend lifecycle — design, build, deploy, monitor, scale — and I can work into the frontend (React) when a project needs it. I prefer long-term, hourly engagements where I can take real ownership, but I'm happy with well-scoped fixed-price work when the requirements are clear. If you want a backend specialist who communicates clearly and ships reliably, let's talk!

Your data is underutilized. Your workflows are still manual. Your backend isn't intelligent yet. I build production-ready AI agent systems, FastAPI backends, and data dashboards that change all three -- end to end, without handoffs. With 5+ years shipping real systems across software engineering, data infrastructure, and AI automation, I sit at a rare intersection: I can architect the agentic AI layer, build the Python backend it runs on, and deliver the Power BI or Plotly dashboard that makes the results visible to your stakeholders -- without stitching together three different freelancers. Most clients reach out with one of these problems: - "We have data everywhere but can't act on it fast enough." - "We're spending thousands of hours on tasks that should be automated." - "We tried an AI solution -- it didn't integrate with anything real." I solve all three. What I Build: AI & Agentic Systems -- Multi-agent workflows (LangGraph, CrewAI), RAG pipelines with vector databases, OpenAI Agents SDK integrations, Anthropic MCP server implementations, and Human-in-the-Loop approval gates for enterprise-grade safety. Backend & API Development -- Production FastAPI services with JWT auth, Docker containerization, PostgreSQL/MongoDB/BigQuery data modeling, Apache Beam ETL pipelines, CI/CD, and GCP/AWS deployments. Systems built for real load, fully documented. Data Analysis & Dashboards -- Interactive Plotly Dash apps, Power BI reports, Looker Studio pipelines, and Quarto-based automated reporting � built for decision-makers, not data engineers. Full-Stack Development -- React and React Native applications. I recently led a full production mobile app modernization: React Native 0.65 ? 0.74, Hermes engine migration, Firebase v22 Modular API -- live users, zero critical regressions. Proof, Not Promises: - Automated ETL pipeline migrating MongoDB to BigQuery via Apache Beam -- now powering real-time analytics on a live production platform - Designed and deployed weekly automated data reports via AWS (Quarto/RMarkdown) for a public health NGO tracking programs across 10,000+ beneficiaries - Built mWater-based M&E survey systems and stakeholder dashboards adopted by government bodies for field-level data collection in Haiti - Currently leading mobile app architectural overhaul at Tekkod LLC -- production system, real users, shipped on deadline How I Work: I map your business problem first, then build in layers: clean API contracts, typed data models with Pydantic, observable agent workflows, and dashboards your team can actually maintain. I document everything and hand off systems your engineers can own. I don't disappear after delivery. Currently: Software Engineer at Tekkod LLC, architecting AI-enabled systems for enterprise clients and leading a full production mobile modernization. This is my daily work -- not a side skill. Let's talk. Send me your project details and I'll tell you exactly how I'd approach it.
