About

A Brief

A passionate engineer driven by curiosity and a love for innovation. I explore the evolving world of AI, always seeking breakthroughs that shape the future. With a focus on emerging trends and tech's societal impact, I thrive on turning complex ideas into exciting possibilities.

Passion

Passion towards innovation and improvement, interested in exploring the world of agents in AI, ardent on building applications with seamless integrations of the latest technologies.

Career Aspirations

I'm deeply thrilled by the possibilities of Machine Learning and aspire to build models that solve real-world problems at scale to deployment—driving impact across industries. Eager to collaborate in teams where I can contribute to both experimentation and production-ready solutions.

Education

Pursuing a Master of Science in Data Science at the University at Buffalo, with a strong focus on machine learning, deep learning, and statistical modeling. Also holds a Bachelor's in Mechanical Engineering from Anna University (Sri Sai Ram Engineering College).

Coursework

Through hands-on projects and advanced coursework, I have gained expertise in building scalable ML systems, analyzing large datasets, and applying AI techniques to real-world challenges.

Current Work

I'm currently exploring and working in reinforcement learning to further expand my knowledge in deep learning through reward-based learning enabling machines to learn efficiently and adaptively.

Experience

University at Buffalo

Research Assistant — AI Systems

March-2026 — Present

MyVictor: Shipped a production university-advising chatbot backed by ~300 automated tests, with async APIs, stateless SSE streaming and non-blocking conversation persistence, all without breaking the existing public API contract.

MyVictor: Cut LLM calls to zero for common list and count questions by running structured database queries directly, and improved answer grounding with Neo4j + Qdrant hybrid retrieval, reranking and self-correcting query repair, evaluated on 37 QA cases.

MyVictor: Locked access down to approved users with allowlisted authentication and ownership-scoped, private conversation history, plus an audited read-only admin view for oversight.

MyVictor: Deployed on OpenShift, standardizing delivery through container orchestration, routing and release management on the university's infrastructure.

Faculty Monitoring: Built a research-intelligence platform tracking 80+ UB faculty across 12 academic and federal sources, using automated ingestion, entity resolution and provenance-aware PostgreSQL/Supabase storage.

Faculty Monitoring: Delivered FastAPI + Next.js workflows that turn retrieval-grounded LLM synthesis into human-reviewable weekly reports on publications and grants, with Gmail/Slack alerts automated through Composio.

Human Cloud Soft Pvt Ltd

Software Developer

May-2023 — June-2024

Built 18 REST API endpoints giving 4 operational teams one place to track inventory, update stock and retrieve records.

Raised inventory accuracy by 35% by replacing manual recordkeeping with React.js interfaces and ASP.NET MVC logic that validates every stock transaction.

Cut inventory audit time by 40% with T-SQL stored procedures, indexed-query tuning and database-driven stock reconciliation.

Hardened the APIs with server-side validation, input sanitization and Postman testing, on SQL Server persistence with AWS deployment support.

Klicknet Info Services Pvt Ltd

Junior Software Developer

April-2022 — April-2023

Created reusable React.js and JavaScript functional components for client-facing web apps, standardizing responsive layouts by almost 70% and removing duplicate UI work.

Connected Flask REST APIs to frontend workflows, backed by unit and API-to-database integration tests that checked business logic, data persistence and error handling before each release.

Built data-driven React views (forms, lists and detail pages) on top of those Flask endpoints, with explicit loading, empty and error states so a failed API call showed a clear message instead of a broken screen.

Validated inputs on both sides of the API contract, with client-side checks for fast feedback and server-side Flask validation for enforcement, so bad payloads were rejected before reaching the database.

Ran the integration tests and a cross-device responsive check on the shared components before each release, so a fix to one component could not regress the client apps that reused it.

L&T Rubber Processing Machinery Pvt Ltd

Design Engineer

November-2021 — February-2022

Worked in the Mechanical design parts of the Hydraulic Tyre Curing and Processing section

Provided Geometric Dimensioning and Tolerance to the 2-dimensional drawings of the mechanical parts of the Hydraulic tyre curing press in Auto-CAD

Updated and maintained records of the products in wrench for hazzle free production control in the bay

Designed the 3 dimensional components of the mechanical parts of the hydraulic tyre curing press in Creo
