Background

Engineer by craft,
builder at heart.

I'm a Full Stack Engineer based in Gurugram, India, working at Byldd IT Limited — a US-based startup studio — where I've spent four years building real products for international clients.

My current focus is an enterprise CRM for a German client, where I own everything from LLM-powered AI insights to AWS deployments to client calls — while leading two engineers on the team.

I enjoy the full stack: designing MongoDB schemas in the morning, wiring up an OpenAI API integration in the afternoon, and tuning a CI/CD pipeline before end of day. I particularly care about making complex systems feel simple to the people using them.

Pursuing an MCA (Online) at LPU, currently exploring SQL/PostgreSQL to round out my database toolkit.

AI-Powered Team Lead Enterprise

A complex enterprise system handling quotations, orders, leads, customers, and inventory for a German B2B company. I own this project end-to-end — architecture, AI features, CI/CD, and client communication — while leading two engineers.

  • AI Insights Engine: Designed and built an LLM-powered analytics layer (GPT-4o) across Customer, Lead, and Quotation modules — generating predictive scores, sentiment trends, risk flags, and next-best-action recommendations.
  • Led the AI rollout: Built the Customer Insights module end-to-end, then defined the reusable architecture and prompting pattern that two engineers extended to Lead and Quotation under my guidance.
  • Inline AI writing assistants: Embedded summarize / shorten / tone / grammar tools into text fields using GPT-4o, plus English/German bilingual output via GPT-4o-mini.
  • Outlook Calendar integration: Integrated Microsoft Graph / Azure AD OAuth 2.0 for in-app scheduling and event sync.
  • Infrastructure: Own CI/CD pipelines, AWS EC2 deployments, and the production database directly.

Mandera Analytics
Privacy-first web analytics · Mar 2024 – Feb 2025
Analytics

A privacy-first alternative analytics platform built from the ground up. I designed the core tracking script, a real-time dashboard, and advanced reporting pipelines.

  • Tracking script: Built the privacy-first tracking script at the heart of the system, capturing analytics without compromising user privacy.
  • Real-time dashboard: React visualization library dashboard giving non-technical users clear insight into traffic, engagement, and behavior trends.
  • Aggregation pipelines: Advanced MongoDB aggregation pipelines (Mongoose) transforming raw event data into detailed reports.
  • CEO recognition: Received the Mountain Mover Award from Byldd's CEO for exceptional delivery of this project.
