About

Computer Engineering student and Backend Engineer specializing in Python, Go, and TypeScript. I design and build production-ready REST APIs, agentic AI systems, and scalable backend infrastructure, from ledger-based financial services to multi-agent LLM workflows.

Experienced shipping real-world products across two internships and hackathon winning projects. Always exploring new ground, from RAG pipelines and agent orchestration to blockchain primitives, while staying grounded in solid engineering fundamentals.

Experience

Sept 2025 - Dec 2025

Backend Developer Intern - Engineer's Cradle

Built a data ingestion service in TypeScript (Bun + Hono) integrating 3+ social media REST APIs to aggregate cross-platform analytics into PostgreSQL for dashboard reporting.

Designed normalised relational schemas for OAuth2 token lifecycle, permission scoping, and integration metadata using Kysely, enabling secure multi-account connections across five social platforms.

Implemented OAuth2 authorisation flows with token refresh and permission management across five providers, ensuring secure and reliable third-party API access.

Exposed normalised REST APIs for analytics dashboards and engineered sync logic handling API rate limits, retries, and provider-specific inconsistencies.

Full Stack Developer - NextGen QuickHire

Led backend development of an online assessment platform using Node.js, Express.js, and TypeScript, designing PostgreSQL database schemas and REST API architecture for test creation, submission, evaluation, and results workflows.

Built and tested REST APIs for the complete assessment lifecycle, applying typed validation with Zod and standardised API contracts to reduce integration bugs and ensure consistent workflow processing.

Implemented a payment module for secure transactions and order tracking using Razorpay, enabling real-time payment processing for the e-commerce platform.

Designed modular backend services using PostgreSQL and MongoDB with query optimisation to support extensibility across multiple platform modules.

Projects

HiFi – Agentic Personal Finance System

Live

Natural language → structured financial workflows via specialized AI agents.

2025Team projectweb2

Breakthrough Concept — Google Cloud & Hack2Skill

Multi-agent platform that routes natural-language prompts to specialized agents, Trader, Tax Filing, Debt Optimization, Compliance, through a controlled orchestration layer. Built with a 3-member team; led backend and agent infrastructure.

FastAPI • Python • Google ADK • Cloud Run • Compute Engine • Firebase • Docker • GitHub Actions
Key highlights
  • Designed agent routing with intent classification and financial rule validation; permissioned execution pipelines ensure agents only run pre-approved, compliant operations.
  • Built REST APIs for prompt ingestion, agent reasoning, and workflow execution with Firebase Auth, authorization middleware, and per-action audit logging.
  • Deployed FastAPI services and agent microservices independently on Google Cloud Run / Compute Engine via Docker and GitHub Actions CI/CD.

Joblyser – AI Job Application Platform

In progress

Resume-grounded job content generation via a distributed async AI backend.

2026Solo projectweb2

Four-service distributed backend: Go API gateway, Python FastAPI, Celery worker, RabbitMQ broker: that orchestrates multi-step AI content generation anchored to the user's resume via a RAG pipeline.

Go • Python • FastAPI • LangGraph • Gemini • Celery • RabbitMQ • ChromaDB • PostgreSQL • MongoDB
Key highlights
  • AI engine built with LangGraph state graph and Gemini LLM: tool calling, schema-validated outputs, and retry guardrails across multi-step generation flows.
  • Async job lifecycle (accepted → queued → processing → complete/failed) via Celery and RabbitMQ — requests return instantly while agents run in the background.
  • RAG pipeline: PDFs parsed with PyMuPDF, chunks vectorized via FastEmbed, indexed in ChromaDB, semantically retrieved at generation time to ground all outputs in resume content.

ChatWithDocs – RAG Document QA

In progress

Ask questions over any uploaded document using vector search and Gemini.

2026Solo projectweb2

RAG-based Q&A system that lets users upload documents and query them in natural language, combining ChromaDB semantic retrieval with Gemini reasoning for grounded, multi-turn responses.

Python • FastAPI • ChromaDB • HuggingFace • Gemini API • AWS S3 • PostgreSQL • SQLAlchemy
Key highlights
  • Ingestion pipeline: upload to S3 via CloudFront → extract text → chunk → embed with BAAI/bge-small-en-v1.5 → index in ChromaDB.
  • Vector similarity search surfaces the most relevant chunks per query, minimizing irrelevant context sent to the LLM.
  • Gemini reasoning layer with multi-turn conversation support and explicit out-of-scope guardrails to prevent hallucination.

Wallet Service – Ledger-Based Transactions

Completed

Immutable double-entry bookkeeping wallet with idempotent transaction processing.

2026Solo projectweb2

Backend financial service in Go where every transaction is a permanent debit/credit ledger entry. Balances are derived state, never stored directly, making reconciliation deterministic and history always reconstructible.

Go • PostgreSQL • SQLC • JWT • Docker • REST API
Key highlights
  • Double-entry model with SQLC type-safe PostgreSQL queries; balance drift is impossible by design.
  • Idempotent transaction processing via client-supplied request IDs prevents duplicate credits/debits under network retries.
  • JWT-secured REST endpoints with strict input validation and structured error handling; containerized with Docker.
