Python / Generative AI Developer — LLM Integrations, RAG Pipelines & AI Backend Systems

Hi everyone,

A few years ago, I was waiting to create this post because I wanted to truly understand real-world project architecture and gain hands-on experience with the tools used in real-time development.

Today, I feel confident that I've built that foundation. I'm ready to take action, work on real projects, solve real problems, and continue growing as a developer.

I'm a Python developer specializing in Generative AI applications, with 2.6+ years of hands-on experience building production-grade systems at IBM and Comviva.

Note: I'm looking to work directly with clients (individuals or businesses with a project to build) not applying as a contractor for agencies, nor for team or full-time positions. If you have an AI/backend project you need built, I'm your person.

Special Mention: My first Every client gets the project done completely free. I'm looking to build a strong portfolio and long-term relationships, so I want to prove my work quality with zero risk on your end.

What I can help you build:

• LLM-powered chat assistants and AI agents (OpenAI, Anthropic, Llama)
• RAG (Retrieval-Augmented Generation) pipelines with vector databases
• Custom chatbots integrated with Slack, Teams, or your own platform
• AI-powered backend APIs (FastAPI / Flask) that scale
• Predictive analytics & ML models (customer scoring, demand forecasting, trend analysis)
• End-to-end automation workflows (issue reporting → AI triage → ticket creation → resolution)

Recent work:

• Built a production AI chat assistant integrated with Microsoft Teams, automating incident ticket creation, routing, and status updates for an enterprise support workflow (IBM)
• Developed a predictive customer analytics platform for a retail client purchase probability + loyalty scoring, with dashboards for sales/KPI tracking (reduced data processing time by 80%)
• Built inventory forecasting and stock optimization systems using Scikit-learn and Flask REST APIs

Tech stack: Python, FastAPI, Flask, LangChain, RAG, Vector Embeddings, Prompt Engineering, PostgreSQL/MySQL, AWS (EC2, S3), Docker, Scikit-learn, PyTorch, Pandas/NumPy

I focus on clean, maintainable code, clear communication, and delivering things that actually work in production not just demos.

If you have a project in mind a chatbot, an internal AI tool, a data pipeline, or something you're not sure how to scope yet feel free to DM me. Happy to do a quick call to discuss what you need.

Again - looking for clients/projects directly, not contractor placements, team roles, or full-time openings.
