I build event-driven microservices, multi-tenant platforms, and LLM-powered pipelines — turning complex engineering challenges into scalable, production-grade systems.
01 / About
Who I Am
I'm a Backend & AI Engineer specializing in building intelligent, distributed systems that scale. I currently work at CollegeDekho, where I architect the backend for Fono — a voice intelligence platform processing 50K+ call recordings daily.
My expertise spans event-driven microservices, LLM orchestration pipelines (Groq, Gemini, Azure OpenAI), and multi-tenant CRM integrations using design patterns like Adapter, Factory, and Strategy.
Beyond engineering, I'm a Codeforces Specialist (Max 1410) with 900+ problems solved across Codeforces, LeetCode, and GFG — a habit that keeps my problem-solving sharp.
I believe great software is measurable — I instrument what I build, profile before optimizing, and treat every production deployment as a feedback loop. Engineering without metrics is just guessing.

Where I've Worked
Backend Developer
Fono — Voice Intelligence & Call Analytics Platform
- Built and scaled backend services for Fono, a multi-tenant voice intelligence platform processing 50K+ call recordings with 500+ daily active users.
- Built an event-driven distributed processing pipeline using RabbitMQ workers and AWS S3 to ingest, process, and analyze call recordings.
- Implemented AI-powered transcription, speaker diarization, and insight extraction pipelines, converting raw audio into structured analytics.
- Architected multi-tenant CRM integrations supporting multiple lead sources using Adapter, Factory, and Strategy design patterns.
Web Monitoring & Information Extraction Platform
- Built a web monitoring system that continuously scrapes official exam and institute websites, detecting updates via snapshot hashing and content diffing.
- Implemented LLM-powered extraction pipelines (Google Gemini & Azure OpenAI) to convert unstructured HTML/PDF updates into structured database records.
- Designed a data pipeline using FastAPI, PostgreSQL, and AWS S3 to store versioned snapshots and structured updates.
Freelance AI Trainer
LLM Benchmarking & Evaluation
- Authored 200+ complex DSA and System Design problems to benchmark LLM code reasoning and debugging capabilities.
- Designed rigorous test suites and edge-case scenarios to evaluate model-generated solution accuracy.

What I've Built
LeadScout
AI-Powered Business Intelligence Platform
Full-stack platform that autonomously discovers and scores 200+ high-potential businesses across Instagram, Google Maps, and YouTube using AI-powered analysis (Groq LLM).
Supports real-time search, filtering by growth metrics, and JWT-authenticated email-verified user accounts for personalized lead discovery.
Features an asynchronous job queue (Celery + Redis) handling 10+ concurrent searches with intelligent deduplication — cutting redundant API calls by 60% — and real-time progress tracking.
Reduces lead research time from hours to minutes for freelancers, agencies, and founders. Deployed on AWS EC2 (t2.small) with PostgreSQL on Amazon RDS.
