Experience
HubSpot CRM Architecture & Administration — CRM Solutions Architect
I owned and administered the entire HubSpot CRM environment, architecting the underlying data model—custom objects (including player profiles), custom properties, and cross-object associations spanning contacts, deals, players, and tasks—that powers a unified customer record across sales, membership, and operations. I designed and maintained automated workflows, deal pipelines, lifecycle stages, and a suite of reports and dashboards that surface revenue, retention, and engagement metrics to leadership, while managing native 3rd-party app integrations that connect HubSpot to the wider marketing and operations stack. I also acted as the organization's CRM owner—translating cross-team business requirements into scalable, well-governed platform configuration, safeguarding data integrity, and continuously optimizing automation to eliminate manual work.
HubSpot Integration & Automation Platform
I designed and maintained the HubSpot CRM integration layer of a Django/Celery data-integration platform that unifies customer, membership, booking, and revenue data from numerous external systems—including Mindbody, Bond Sports, SmartWaiver, and Beambox, as well as the company's in-house social and sports-gaming venues—into a single CRM source of truth. I built real-time webhook pipelines and scheduled batch syncs that create, enrich, and reconcile HubSpot contacts, deals, custom player objects, and follow-up tasks through the HubSpot REST API, backed by asynchronous Celery/RabbitMQ processing, Snowflake-driven analytics queries, and automated failure alerting—giving sales and operations teams a continuously updated, 360° view of every customer across the business.
AI Sales Call Analysis
A call analysis project to analyze internal outbound sales calls and provide insights to the operations team. Automatic intent detection, summarization, areas for improvement, and more are automatically captured. It's easily customizable to serve different kinds of businesses.
MissileDodge—A Browser-based Game
https://missiledodge.srikardurgi.comI created a browser-based game where you destroy the enemies by dodging the incoming missiles. I developed many updates to the game based on user feedback. I built it using Claude Code and deployed it on Cloudflare with a global leaderboard.
Email Open and Click Tracking System
Developed an open-and-click tracking system that can track all emails sent by the email monetization application. Used the client-server as an NGINX reverse proxy and forward proxy, thereby hiding the main server used in tracking.
N-Queen Puzzle Using Genetic Algorithms
Designed an N-Queen puzzle solver in C++ using genetic algorithms that can solve 500 Queen puzzles in a minute. The program involved the steps of population generation, feature selection, mutation, and fitness function.
Machine Learning MOOC Projects
Charity donor prediction using decision trees and logistic regression, multi-character recognition using convolutional neural networks, and isolation game agents using alpha-beta pruning minimax as part of the online MOOC.
Micro Neural Network Library
Created a lightweight neural network library that supports APIs to create a multi-layered perception similar to PyTorch. I created backpropagation functions that support various operations and added visualization tooling to the library for debugging purposes.
Finance Fun
http://financefun.srikardurgi.comA series of fun applications that make exploring finances engaging. They allow users to enter salary data over time and compare it across different currencies, such as gold, cryptocurrencies, and indices. More applications are in the pipeline.
DigitalYou
A full-stack app that clones a user's voice from a guided interview and lets them hold real-time spoken conversations with an AI persona grounded in their own documents and answers.
Engineered the retrieval and streaming layer: paragraph-aware chunking with embedded SQLite-vec similarity search, and an OpenAI-compatible SSE gateway that serves an ElevenLabs voice agent as its custom LLM with per-turn RAG injection across pluggable Claude/OpenAI back ends.
