About

Maxma Tech Consulting is the consulting practice of Unmey Mahaddalkar, a full-stack engineer with 6+ years building production-grade web applications for enterprise teams. Maxma is the vehicle used to contract and invoice client work — the engineering is done by Unmey directly.

I'm Unmey Mahaddalkar — a frontend-focused full-stack engineer based in Vancouver, BC. Over the past six years I've shipped enterprise React, Redux and TypeScript applications in Agile teams across Canada, the US and India: payroll and tax management systems, AI-powered chatbots, and PDF annotation tools used by thousands of ADP customers. I'm a Canadian permanent resident, so no sponsorship is required.

What Maxma does

Maxma Tech Consulting takes on contract and consulting engagements for software teams — typically as an embedded engineer or a focused build partner.

Web application development

End-to-end delivery of React, TypeScript and Next.js applications — from component architecture and state management (Redux Toolkit) to REST API integration and accessible, responsive UI.

Enterprise UI & design systems

Building and maintaining mission-critical interfaces at scale: WCAG-accessible design systems, complex forms and workflows, cross-browser components, and performance optimization.

Full-stack delivery

Node.js and Express APIs, PostgreSQL and MongoDB data layers, CI/CD pipelines, and testing with Jest and Selenium — owning the full cycle from ticket to production.

AI-integrated development

Practical use of Claude, GitHub Copilot and Amazon Q to compress delivery timelines — including GenAI pipelines and LLM chatbots that have cut multi-week processes down to hours.
