About

I'm a Senior Full Stack Engineer with 6+ years crafting production-grade React and Node.js applications end to end — from resilient databases to polished, high-performance interfaces. My focus is scalable system design and solution architecture across the frontend and backend: multi-tenant architecture, solid design patterns and OOP principles, distributed-systems trade-offs (CAP theorem), gRPC and Protocol Buffers, dynamic connector-based integrations, event-driven workflows, and the caching and query work that keeps platforms fast as they grow.

At Growexx I own the architecture for FirmProfit, a multi-tenant legal-tech automation platform with a fully dynamic, connector-based workflow engine and schema-driven forms — configurable per tenant with no code changes. Before that I led design and optimization across 25+ systems spanning health-tech, e-commerce, EdTech, and AI/SaaS.

I care about clean, maintainable code built on solid design patterns and OOP principles, plus mentoring and shipping. I work well in agile / Scrum teams, lead code reviews, and enjoy owning features end to end while helping the people around me level up.

Experience

Growexx

Senior Software Engineer
Oct 2024 — Present · Ahmedabad
  • Own FirmProfit end to end — a multi-tenant legal-tech SaaS platform on NestJS/Node.js in TypeScript, React with Next.js (SSR), and PostgreSQL — driving architecture across microservice boundaries, event-driven workflows, and caching.
  • Designed a connector-based workflow engine and JSON schema-driven form system that cut client configuration time by ~55%, and built the front end that consumes it.
  • Design, build, and consume REST APIs powering self-service integrations across four third-party platforms (Clio, MyCase, Outlook, Google), each mapped to per-tenant configuration.
  • Delivered 2 additional SaaS products alongside the core platform: Hirin (hiring automation) and SimpleMusic (Stripe subscription billing).
  • Hardened the platform with tenant-scoped RBAC, 2FA, and SOC 2-aligned data isolation across 3+ client firms, and debug across the stack — React rendering and state, Node service failures, slow SQL queries.
  • Mentor 4 junior developers and lead code reviews, enforcing clean code and Git branching/PR discipline — cutting critical SonarQube issues by 85%.
  • Work with product managers, designers, and client stakeholders to turn business requirements into technical specs, reducing mid-sprint rework by ~25%.

  • Shipped and maintained 25+ full-stack applications with Node.js / Express.js / NestJS APIs and React front ends — including Ivira, Kiksasa, and Goat Grub — earning promotion from Junior to Senior Developer.
  • Ran performance audits and optimized APIs, SQL queries, and database schemas, reducing server load by 65% under heavy traffic.
  • Improved React front-end performance through code splitting, lazy loading, and memoization, cutting page-load times by 70%.
  • Delivered high-performance search and Stripe payment integrations across e-commerce and SaaS products, cutting search latency by ~50% via query optimization, indexing, and result caching.
  • Led code reviews, testing, and deployments across concurrent projects, reducing post-release defects by 85% while consistently meeting sprint deadlines.
  • Managed multiple projects simultaneously and partnered on sprint planning and estimations — earning my manager's trust with urgent, high-priority work while keeping deadlines met and clients satisfied.
