Remote

Worked on backend systems using Python, Flask, and FastAPI, delivering production-grade APIs. Identified major performance bottlenecks caused by excessive external API calls and redesigned the data-access layer using MongoDB to reduce dependency on repeated API requests. Eliminated millions of redundant API calls, significantly improving system efficiency and stability. Optimized backend processing workflows, reducing execution time for ~2,000 delivery records from 2–4 hours down to 30–40 minutes. Debugged and fixed critical production issues, improving reliability and correctness of existing backend services. Refactored and optimized an existing algorithm that failed under large-scale inputs, enabling the system to handle high-volume deliveries without breaking. Collaborated closely with stakeholders to analyze system constraints, propose architectural improvements, and implement scalable backend solutions.

Developed and maintained 50+ micro AI applications using Python, Streamlit, and the Lyzr SDK, enabling rapid experimentation and validation of GenAI use cases across multiple industries. Built an Ask Me Anything (AMA) AI bot using FastAPI and internal services to generate voice-based, persona-driven responses from custom datasets. Designed and delivered backend APIs with FastAPI to support internal tools and customer-facing AI demos. Integrated the Lyzr Agent SDK to build intelligent assistants showcasing platform capabilities for prospective customers and internal solution teams. Created technical blogs, developer guides, and community content (Medium, Dev.to, Quora) to drive developer adoption and product awareness.

Built and maintained backend services using Python and Flask, with PostgreSQL for data storage and query optimization. Designed and consumed RESTful APIs, working with ORM-based database models to handle application logic and data persistence. Worked in an Agile development environment, actively using JIRA for sprint planning, issue tracking, and bug resolution. Collaborated with team members to understand requirements, implement features, and adapt quickly to changing project needs. Gained hands-on exposure to Machine Learning and Generative AI fundamentals, supporting data-driven and AI-enabled features at a basic level.

Backend Engineer (Python) | GenAI & LLM Applications | FastAPI, Streamlit

About

I’m an AI Developer with hands-on experience building Generative AI and backend systems using Python, FastAPI, and LLM-based workflows. I’ve worked on developing production-ready GenAI applications, API-driven backends, and internal tools focused on automation, AI-assisted workflows, and data-driven decision-making. My experience spans prompt engineering, LLM integration, backend architecture, and deploying AI-powered applications using modern Python frameworks. I focus on building real systems, - clean APIs, scalable logic, and AI features that actually solve business problems. Currently working as a Python Developer, with prior experience at Lyzr AI and CubexO, contributing to AI-driven products and backend services.
