FastAPI & LangChain RAG Pipeline Optimization
Abdur diagnosed and fixed multiple issues in our live RAG pipeline retrieval quality, embedding performance, and a broken FastAPI endpoint all within a few hours. He identified the root causes immediately without back-and-forth, explained what he found clearly, and delivered clean, well-structured code. Exactly the kind of backend developer you want when something is broken in production. Will hire again.

Bug Fixers Needed โ $1,000 Flat Fee โ Case Management System Cleanup
The developer started off strong and initially completed assigned development tasks in a satisfactory manner. However, after receiving a new sprint of tasks, he quit in the middle of the project without proper notice, explanation, or transition support.
This caused disruption to our workflow and forced us to rearrange staff to cover unfinished work. While his early performance showed potential, his lack of professionalism and failure to communicate before abandoning the project created unnecessary delays and operational problems.
For that reason, I cannot recommend him for work requiring reliability, long-term commitment, or responsibility on an active software project.

What I build:
- ๐๐ ๐๐๐๐ & ๐๐๐ ๐๐ซ๐จ๐๐ฎ๐๐ญ๐ฌ:
I design and ship AI-powered SaaS applications and AI copilots using GPT-4o/GPT-5, Claude, and Gemini, integrated into Node.js/Python backends with clean, secure architecture.
- ๐๐๐ & ๐๐ง๐ญ๐๐ซ๐ฉ๐ซ๐ข๐ฌ๐ ๐๐ง๐จ๐ฐ๐ฅ๐๐๐ ๐ ๐๐ฒ๐ฌ๐ญ๐๐ฆ๐ฌ:
I build Retrieval-Augmented Generation systems, semantic search, and vector database pipelines (Pinecone, Weaviate, pgvector) that turn messy enterprise documents into fast, accurate AI search and Q&A.
- ๐๐ ๐๐ ๐๐ง๐ญ๐ฌ & ๐๐จ๐ซ๐ค๐๐ฅ๐จ๐ฐ ๐๐ฎ๐ญ๐จ๐ฆ๐๐ญ๐ข๐จ๐ง:
I develop autonomous AI agents and business-workflow automations that handle document processing, OCR data extraction, and multi-step tasks without manual intervention.
๐ ๐จ๐ซ ๐๐ฑ๐๐ฆ๐ฉ๐ฅ๐, I built a document automation pipeline combining OCR extraction and an LLM based classification layer, reducing manual data entry time for a logistics client and a RAG based internal knowledge base for a healthcare team that replaced hours of manual search with instant, cited answers.
On the full-stack side, I work across React.js, Next.js, TypeScript, Node.js, NestJS, Python/FastAPI, and Django, with PostgreSQL, MongoDB, and Redis for data layers, deployed on AWS/GCP with Docker, Kubernetes, and CI/CD pipelines. I also build cross-platform apps with Flutter and React Native when a product needs mobile reach.
I'm a ๐๐จ๐ฉ ๐๐๐ญ๐๐ ๐๐ฉ๐ฐ๐จ๐ซ๐ค ๐๐ซ๐๐๐ฅ๐๐ง๐๐๐ซ known for fast communication, production-ready system design, and long-term technical partnership not just one off delivery. If you're looking to build or scale an AI-driven product, Let's talk about your project.
