About me
Hi, I'm Mayank. I build web apps and internal tools for small businesses - inventory systems, dashboards, and admin panels that replace messy spreadsheets. My biggest project is a full ERP system built from scratch: inventory, purchasing, sales, HR, payroll, and a reporting dashboard. I designed the entire database myself using Next.js, TypeScript, Prisma, and PostgreSQL. I use AI heavily in my workflow to build faster without cutting corners on data structure or security. I keep scope clear from the start so you always know what you're getting.... Read more

Designed and built a full-stack manufacturing ERP system from scratch, on my own. It covers inventory and warehouse management, purchasing (suppliers, purchase orders, goods receipts), sales (customers, orders, invoicing, payments), HR (workers, attendance, leave, payroll), and a live reporting dashboard across all modules. I designed the entire database myself — over 60 connected tables in PostgreSQL via Prisma — with multi-tenant data isolation so each business's data stays fully separate. Built role-based access control, audit logging for every create/update/delete action, and a reporting engine that pulls real-time KPIs and analytics from the underlying data. Stack: Next.js 15, TypeScript, Prisma, PostgreSQL, Tailwind CSS, and shadcn/ui on the frontend. I used an AI-assisted workflow throughout, which let me move fast while keeping the architecture clean — service layer, validation, and permission checks are consistent across every module. This project taught me how to think about data modeling, tenant isolation, and system design at a level a typical small project doesn't get you to, and it's what I now bring to client work — clear scoping, solid data structure, and no shortcuts on how information is stored or secured.
