Experience

Founding Engineer for AI Powered Insurance Quote Comparison

I built a commercial-grade quote-comparison engine using modern UI frameworks and durable agentic-AI workflows, providing real-time insights. This development improved data accuracy and reduced the manual processing effort by 75% for client-facing operations.

I fine-tuned domain-specific ChatGPT and Claude models by optimizing prompts, training data, and routing logic. This effort cut token usage by 50-60% while elevating the precision, consistency, and quality of client service.

Additionally, I established an end-to-end CI/CD and deployment infrastructure using Docker, GitHub Actions, and Caddy/Rails, and led a cross-functional team to accelerate feature delivery cycles. This infrastructure improved release reliability and enabled faster iteration, benefiting stakeholders with more timely updates and enhancements.

Fitness App with Gamified, Custom AI Generated Workouts

https://kovofitness.com/
I led a team of three developers to implement a cross-platform fitness app for iOS and Android, utilizing generative AI to create customized workout plans for individuals. I implemented the AI-powered workout generation engine, which gamifies the workout experience for app users.

For the back-end infrastructure, I set up a robust environment using Cloudflare, Caddy, and Linode Kubernetes to host the API service, integrate with the OpenAI API, and manage the production database. Additionally, I hired and managed developers to ensure a pixel-perfect UI/UX implementation based on the Figma designs, ensuring the final product was visually compelling and user-friendly.

Crowdfunding Investment App with a Social Element

https://loupt.co/
I built an MVP web app for Loupt LLC using React front end, Express.js back end, MongoDB data store, and Amazon S3 object-store. The web app leverages crowdfunding to allow non-accredited investors to invest in and own equity in early-stage startups.

Twilio-based WebRTC App

Designed and created a progressive web app that empowers businesses to conduct remote inspections. The product supports various workflows, such as inventory audits and remote insurance claims.

In addition to providing a robust WebRTC-based video conferencing experience that allows for self-recovery in bad network conditions, the app also allows capturing high-resolution pictures with geo-tagging.

The new web app was built from the ground up and achieved a success rate of >97% for remote inspections compared to just 85% for the previously used solution.

Live Video Lectures Platform

https://www.slideshare.net/UjjavalVerma4/aws-powered-online-classes-platform
I designed and implemented a RESTful microservice that leveraged AWS Elemental MediaLive and MediaConvert pipelines to live streams and video-on-demand lectures and tutorials for users of the Pariksha Edutech mobile app (Pariksha.co).

The in-house implementation supported over 100 concurrent streams and achieved a low latency of fewer than 12 seconds compared to YouTube's 25-second and Vimeo's 30-second latency for live streams.

Health Monitor for NAO

Developed a GUI-based monitoring application in Python to monitor various hardware parameters of NAO humanoid robot used in robot soccer. It enabled remote monitoring via wifi connectivity. The project was presented in the Research and Development Showcase 2010.

Distributed Power Set Generation

Designed a distributed algorithm to represent the power set of a set in quadratic space and time complexity. Generated a power set of 30,000 elements in under two minutes and 10GB storage using a cluster of eight computing nodes.

Student Admission Portal

Developed a web-based portal to centralize the process of room allotment, mess registration, and payment receipts generation. The portal facilitated new admissions at IIIT, Hyderabad, for the academic session of 2010.

Virtual Labs Experiments

https://www.vlab.co.in/participating-institute-iiit-hyderabad
I developed Java applets that allowed for conducting civil engineering experiments on a computer virtually. These interactive simulations were deployed as part of the national Virtual Labs initiative of the Ministry of Human Resource Development, Government of India.
