Websites • Client Portals • AI Chatbots
Your business, booking clients
while you sleep.
I build websites, client portals and AI chatbots for clinics, realtors, coaches and schools — so enquiries turn into bookings 24/7, without extra staff.
About Me
I'm Shubham Kumar — a software engineer who designs and builds production systems end to end: system design, backend, frontend, deployment and the AI layer on top.
In my day job at Diyos Infotech, I build and run microservices used by 10,000+ people daily — 300+ APIs, CI/CD pipelines on AWS, and systems held to a 99.5% uptime standard. Reliability and scale aren't extras in my work; they're the default.
Through my studio, Bytencia, I build the same standard of system for smaller businesses: websites that book clients while you sleep, client portals that replace Excel-and-WhatsApp admin, and AI chatbots that answer and capture enquiries around the clock.
Everything is fixed price, agreed in writing before we start — no hourly billing, no surprises.

Featured Project
ReportFlow — GitHub Analytics Platform
- ▹Problem: Teams were creating and sharing reports manually — slow, error-prone, no control over who sees what.
- ▹What I built: A GitHub analytics platform (React + TypeScript front end, Spring Boot APIs, PostgreSQL, GitHub OAuth login, AWS) with role-based access for 3 roles — Admin, Manager and Developer — and real-time GitHub data sync.
- ▹Result: Manual processing time down 40%, high-volume records handled with query performance up 50%, 99.8% availability — architecture built to scale with data growth.

Featured Project
GMS — Global School Management System
- ▹Problem: Schools juggling admissions, attendance and reports across paper, Excel and WhatsApp.
- ▹What I built: A complete multi-tenant school management platform (Spring Boot + React) — five role-based experiences (Admin, Teacher, Student, Parent, Staff), each with their own login, dashboard and permissions; smart dashboards and automation replacing the registers, spreadsheets and WhatsApp threads.
- ▹Result: Five user types working in one system, records entered once and consistent everywhere, and the whole school visible from a single dashboard — engineered to handle massive, high-volume data to the production standard of systems serving 10,000+ daily users.
