Kandala Guruprasad
Senior Frontend Engineer | React & Next.js
I build production-grade web applications using React, Next.js and TypeScript — from multi-role SaaS platforms and marketplace systems to ERP tools and client-facing business sites. Most of my work involves complex frontend architecture: role-based access, payment integrations, and dashboards that reflect real business workflows.

About
Building real products with React since 2020.
I've been building web products since 2020 — starting as a freelance frontend developer, then spending 4+ years at Code Stream Technology building production SaaS platforms, coaching marketplaces, agri platforms, audit tools, and ERP systems. All real products, all real users.
Most of my work sits at the intersection of complex business logic and frontend implementation — multi-role access systems, payment flows, dynamic forms with validation, and dashboards that pull real data. I work closely with backend engineers and directly from Figma designs to ship features end-to-end.
Across 5 production applications, I've been the person who owns the frontend — component architecture, API integration, state management, and making sure the UI handles every edge case the business throws at it.
System Architecture
Component structure, routing strategy, and state management planned before a line of code is written.
Performance First
Route-level code splitting, lazy loading, and memoization applied across large dashboard interfaces.
Payment Systems
Stripe and Razorpay checkout flows built across multiple platforms — including status handling, retries, and enrollment confirmation.
Auth & RBAC
JWT-based role systems implemented across every platform — route guards, API permissions, and per-role dashboard views.

Also delivered - internal business systems
ERP platform
SGreens ERP System
The business was managing inventory on spreadsheets, HR records manually, and invoices on paper. There was no single view of operations — stock levels, employee records, and financials all lived in separate places, causing delays and frequent data errors.
Replaced 4+ disconnected tools (spreadsheets, manual HR records, paper invoices) with one unified system
ViewERP system
Sree Veeranjaneya ERP System
The company was tracking spare parts inventory, customer records, and vendor data entirely on paper and in spreadsheets. Billing was manual, invoices were generated by hand, and there was no way to view sales performance over time. Every process was slow and error-prone.
