Developing and maintaining fullstack AI-driven applications using Django (backend), React (frontend), and PostgreSQL (database). Building scalable backend APIs, implementing business logic, and integrating AI modules into production systems. Applying prompt engineering and fine-tuning of LLMs to deliver intelligent features across client and internal projects. Designing reusable and testable components, ensuring high code quality with unit testing and CI/CD pipelines. Collaborating with cross-functional teams on end-to-end feature delivery, from architecture design to deployment. Leveraging cloud and container technologies (Docker, GCP, GitHub Actions) for deployment and scalability. Optimizing system performance and ensuring reliability through logging, monitoring, and error handling.

ConneqtedAgents

Software Engineer I (Backend / MLOps)

Jan 2025 – Aug 2025

Built and maintained a production-grade backend with FastAPI, PostgreSQL, and Redis. Developed CI/CD pipelines using GitHub Actions for Dockerized builds, tests (Pytest), and deployment to AWS EC2. Integrated Celery for background tasks (e.g., model inference, notifications), improving API throughput by ~40%. Managed cloud resources with AWS S3 (file storage), IAM policies (access control), and AWS Lambda (serverless inference tasks). Ensured reliable deployments using environment variable configurations for staging and production. Added structured logging, error tracking, and service health checks for observability. Collaborated in feature design, code reviews, and version-controlled releases via Git.

NeuralFrameAi

Junior AI Engineer (Backend / FastAPI Focus)

Mar 2024 – Dec 2024

Developed AI-powered APIs with FastAPI, serving endpoints for auto-question generation and semantic search. Integrated ML pipelines with LLMs and custom models, including work on source codebases like LTBoost and MICN. Built backend modules with PostgreSQL, JWT-based auth, and optimized SQL queries for low-latency access. Participated in architecture decisions for LLM-backed features in an education-focused AI platform. Fine-tuned LLMs using Hugging Face for domain-specific question generation and sentiment analysis tasks. Built a Key Information Extraction pipeline for processing and summarizing long academic texts. Applied prompt engineering techniques to reduce hallucinations and improve output consistency across LLM features. Processed and cleaned text data using Pandas, NLTK, and regex-based workflows for model training pipelines.

Archexify

Backend Developer (Contract / Freelance)

Jan 2021 – Feb 2024

Delivered backend development and Python-based automation for small business clients on a contract basis. Built REST APIs, admin panels, and internal tools using Django, Flask, and FastAPI with PostgreSQL and MySQL backends. Designed relational database schemas, implemented business logic, and integrated third-party APIs (payment, messaging, auth). Handled deployment on VPS and cloud environments (Linux, Nginx, Gunicorn) with basic CI workflows. Collaborated directly with clients to gather requirements, scope features, and ship production-ready software end-to-end.
