Work Experience

Frontend & R&D Engineer Intern

Flam

Aug 2025 - Mar 2026

Led R&D and frontend engineering for a browser-based video editor sourced from the internal GitHub channel, building timeline keyframing, GLB gizmo controls, and text transition animations that became the production core of Flam’s interactive media pipeline. Optimized GLB overlay performance by eliminating redundant mesh-level animations, improving timeline playback and canvas rendering, and developed custom 3D gizmo controls integrated with Remotion and Three.js. Implemented a Mastra + OpenAI function-calling pipeline enabling NLP-driven control over canvas state, overlay sequencing, and image-to-video generation and leveraging agent architectures to automate complex frontend workflows via natural language commands. Built a grouped QR scanning platform and AR experience management dashboard, designing full-stack flows to manage, publish, and monitor interactive AR campaigns while reducing deployment overhead; also contributed to the FlamApp interactive portfolio experience.

Software Development Engineer Intern

MANNIT

Feb 2025 - Jul 2025

Identified Pinecone API quotas as a bottleneck; architected a hybrid FAISS indexing layer on high-GPU/CPU cloud platforms, cutting cloud vector search costs to near-zero and reducing query latency 3–5x from seconds to milliseconds for production LLM applications. Designed an admin-driven vector database pipeline with automatic category generation and dynamic user-specific data isolation, enabling real-time category updates that scaled with data growth and eliminating hardcoded configuration from the backend. Built PostgreSQL-backed authentication with chat history persistence and an admin dashboard for embedding management, integrating REST APIs to improve session reliability and provide full visibility into user interaction data across the platform. Engineered a scalable, production-ready codebase analysis system for 10,000+ file repositories via AST parsing, smart filtering, and batched async processing, eliminating sequential blocking calls and enabling fast, large-scale repo analysis for AI-assisted tooling.

Software Development Engineer Intern

Telesto Energy

Oct 2023 - May 2024

Built FastAPI and Django backends for real-time energy data ingestion; normalized MySQL schemas improving query performance across energy monitoring pipelines. Integrated ML models for predictive analytics on energy consumption. Developed a landing page with a CSV-upload analysis tool that generates seismic data visualizations using Plotly.js on a Django backend.
