Gokul Rajendiran.

I build the platforms AI runs on — and the tools it uses.

4+ years engineering Zoho CRM's core — a 17,000-class multi-tenant platform. Along the way: a 128-tool MCP server and a dual-engine browser built for AI agents.

About Me

Backend engineer with 4+ years on the core of Zoho CRM, a 17,000-class multi-tenant Java SaaS platform.

I own the metadata and query-engine internals, where multi-tier caching (in-process plus Redis) and PostgreSQL query tuning cut key response times by up to 30%. I also build AI developer tooling, including a 128-tool MCP server over the CRM codebase and a dual-engine browser that lets AI agents drive real web apps.

With a B.E. in Computer Science from RMK College of Engineering (CGPA: 8.5, First Class with Honors), I bring a strong foundation in data structures, algorithms, and system design to every project I work on. I'm looking for backend or platform engineering roles where scale, performance and developer productivity matter.

Beyond work, I'm an active competitive programmer with 5000+ problems solved across platforms, and I've been recognized in national hackathons including Smart India Hackathon.

CRM MCP Server

A Model Context Protocol server that gives AI agents deep access to Zoho CRM's million-line codebase — with a self-learning usage layer, a knowledge graph, and a Java AST index covering 17,000 classes. The kind of tool this very portfolio's terminal is pretending to be.

##Highlights

• 128 tools across 28 groups — code search, ORM/DS-Query helpers, metadata lookups, and knowledge-graph queries, served over STDIO, SSE, and streamable HTTP so any MCP client can connect.
• Java AST index — 17,165 classes and 233,000+ methods parsed from CRM source, so agents jump straight to a definition instead of grepping a million lines.
• Self-learning layer — an aiosqlite usage store tracks which tools actually help and ranks them accordingly; the server gets sharper the more it's used.
• Knowledge graph — entities and relations extracted from the codebase connect modules, tables, and APIs so agents can reason about how pieces fit together.
• Built-in dashboard — a FastAPI + Jinja2 + HTMX web UI for inspecting tool usage and the learning layer in real time.

AI Browser + claude-web-bridge

A dual-engine browser built for AI agents — Lightpanda for speed, Chromium over CDP for fidelity — plus a Manifest V3 bridge extension that lets Claude drive real, logged-in web apps: shadow DOM, accessibility tree, heavy SPAs and all.

##Highlights

• Two engines, one API — Lightpanda for fast, lightweight page work; Chromium via the DevTools Protocol when full rendering fidelity matters. The agent never has to care which one is underneath.
• Agent-grade actions — click-by-text, shadow-DOM-aware form filling, drag-and-drop, keyboard input, accessibility-tree snapshots, and network-idle waits — the primitives an AI needs to use real web apps reliably.
• claude-web-bridge — a Manifest V3 extension that drives the user's own logged-in browser through chrome.debugger: trusted clicks via Input.dispatchMouseEvent, JS via Runtime.evaluate, screenshots of background tabs.
• Shipped as a platform — a pnpm monorepo with an MCP server, a JS SDK, and a published Python SDK (ai-browser-sdk, Python 3.10–3.13), tested with vitest in CI.

Zoho CRM Core Platform

The day job: the metadata and query internals of Zoho CRM — a 17,000-class multi-tenant SaaS. I work on the crmmeta query engine and module customization, tuning hot paths with a custom ORM, DS Query DSL, and multi-tier Redis caching.

##What I actually touch

• crmmeta query engine — the metadata layer that turns module and field definitions into SQL, with every org isolated by tenant in a single multi-tenant deployment.
• AdventNet persistence + DS Query — the in-house ORM and SQL DSL used across 5,000+ files of the codebase; I work on the query paths everything else sits on.
• Caching & performance — multi-tier caching (in-process + Redis) and query optimization that cut key response times by up to 30% in production.
• Platform plumbing at scale — Struts2 routing across 18 config files covering API v2–v10, Spring MVC with AOP interceptors, Kafka events, gRPC services, and Hystrix circuit breakers.

Product Management App

The internship project: picked up Zoho's internal client framework from scratch and built a complete product management application on Java MVC — recommendations, ratings, and quoting included. Built during the internship that converted into the full-time role.

##Highlights

• Internal framework, learned cold — ramped up on an in-house client framework with zero prior exposure and shipped a working application on it within the internship window.
• Product suggestions — a recommendation module that ranks products by a blend of user ratings and price.
• A ratings feedback loop — product ratings improve as users purchase and review, so the catalog gets more trustworthy the more it's used.
• Quotes & dynamic discounts — quote generation tied to user profile ratings: stronger profiles unlock better discounts.
• Requirements → features — translated business requirements into REST-aligned backend modules: recommendations, the discount engine, and the rating system.
