Work Experience

Associate Software Engineer

Homeville Group

Jan 2025 - May 2026 Mumbai
  • Re-architected the Singularity CreditWorld RM module, resolving stale data and race conditions by consolidating MySQL queries and Firebase service calls into a unified reactive data layer used concurrently by internal and external lending teams; integrated with the AI extraction pipeline to surface parsed document data within the loan origination workflow
  • Built the Bharat Housing Network document vault end-to-end: REST APIs, MySQL schema design and AWS S3 storage for loan applicant, property and identity documents; shipped an embedded chatbot backed by a context API serving real-time journey data to internal teams and external lending companies
  • Owned the EaseBuzz payment integration end-to-end: server-side webhook for payment verification, MySQL status updates, downstream workflow triggers and Pusher WebSocket notifications across CRM, LOS and LMS; contributed to the team Angular 17 to 19 migration that cut bundle size by 83 % and build time by 64 %

Web Developer Intern

Zidio Development

Jun 2024 - Sep 2024 Remote
  • Built a full-stack MERN job portal with JWT authentication, application-level role-based access control with separate permission scopes for employers and job seekers, and custom Express middleware for auth, error handling and request validation
  • Implemented compound indexes for multi-field search across job titles, locations and categories with server-side pagination and filtering, and built REST APIs covering job listings, application tracking and candidate management

Software Developer Intern

Tata Steel Limited

Aug 2023 - Jan 2024 Mumbai
  • Built a centralised React.js dashboard backed by Node.js REST APIs serving machine-wise and plant-level OEE metrics per shift, replacing manual shift reporting across multiple manufacturing units and production lines
  • Built a Python pipeline using Pandas and NumPy to parse and normalise machine exports, and applied ARIMA models via pmdarima auto-order selection and statsmodels fitting to forecast OEE values 12 months ahead across 3 plants and 30+ machines

Projects

GoSQLiteWebSocketTCPREST APIGitHub Actions
  • Built a self-hosted localhost tunnel in Go using binary TCP transport with a custom framed protocol for reliable bidirectional request forwarding, serving as a drop-in ngrok alternative with zero external runtime dependencies
  • Shipped a terminal-style inspection dashboard embedded directly in the binary with SQLite persistence, request mutation, replay and live WebSocket updates; hardened with token-gated tunnel registration, HttpOnly cookie auth and ACME TLS

Cipheria

Next.jsFastAPIPostgreSQLAlembicRedisAES-256-GCMPBKDF2-SHA256JWT
  • Architected a zero-knowledge model where all encryption runs client-side via AES-256-GCM with keys derived using PBKDF2-SHA256 at 600 k iterations, so the server stores only ciphertext and the master password is never transmitted
  • Hardened the API with Redis-based per-endpoint rate limiting and JWT rotation featuring short-lived access tokens with refresh token reuse detection, making credential-stuffing attacks computationally expensive

Berkshire Hathaway Intelligence

Next.jsTypeScriptMastraPostgreSQLpgvectorMistral EmbeddingsOllama
  • Built an end-to-end RAG system over 48 years of Berkshire Hathaway shareholder letters, designing the full ingestion pipeline fromPDF parsing through MDocument chunking to batched pgvector upserts with per-source re-ingestion support
  • Wired a Mastra agent with Mistral embeddings and pgvector retrieval for grounded responses, persistent PostgreSQL-backed conversational memory across sessions, and a streaming Next.js chat UI with clickable source attribution

Juris AI

AngularNode.jsMongoDBGoogle Gemini APIJWT
  • Built a legal query platform that grounds every answer in live web sources by chaining Google Search retrieval, context injection and Gemini generation, reducing reliance on model memory for legal responses
  • Preprocessed raw queries to extract legal intent before retrieval to improve answer relevance, and structured the RAG pipeline to cleanly separate query understanding from context injection and generation
