About

I'm an engineering undergrad at BMSIT&M, Bengaluru, who enjoys building products and solving engineering problems end-to-end. I've taken PUC Notes & Solutions from an idea to an educational platform serving thousands of students, built AiiN, a real-time AI interview platform using FastAPI and PostgreSQL, and have contributed 330+ hours evaluating enterprise LLMs at Outlier.

Products and software systems built to solve practical problems.

PUC Notes & Solutions

Built and scaled a public educational resource platform serving 5,000 to 10,000+ monthly active students across Karnataka. Owned zero-to-one execution, search engine indexing (SEO), content architecture, and ongoing maintenance.

AiiN — Real-Time AI Interview Rehearsal Platform

Engineered a modular backend using FastAPI, PostgreSQL, SQLAlchemy ORM, and Alembic with an 8-entity relational schema and Repository-Service architecture. Integrated WebSockets, Speech-to-Text, and Gemini API to parse resumes/JDs, run live voice mock interviews, and generate downloadable PDF evaluation reports via PDFKit.

Core Systems & Embedded Builds

Deterministic firmware, RTOS-driven architectures, and IoT hardware integrations.

EVSE Charge Controller Simulator (FreeRTOS)

Architected a deterministic Electric Vehicle Supply Equipment (EVSE) charge controller simulator on ESP32-S2 using FreeRTOS. Replaced single-loop polling with 4 concurrent tasks (Input, EVSE FSM, Logger, Fault) communicating via queues, mutexes, and ISR-triggered binary semaphores, alongside hardware LEDC 1 kHz PWM pilot signal generation (IEC 61851).

Smart Switching — Bidirectional IoT Automation

Built a dual-mode home automation system on ESP32 controlling 4 AC relay loads via local hexadecimal IR remote decoding and cloud-connected Blynk mobile/web dashboards, maintaining real-time bidirectional state synchronization across physical hardware and cloud interfaces.
