How I work
From brief to a product that stays up.
- 01
Brief
You tell me what the product must do, who uses it and when you need it.
You get
Questions and a scoped plan back to you. No call needed to start.
- 02
Build
Interface, API and data in one pass, by one person.
You get
A working link every week to steer with, not slides.
- 03
Ship
Docker, CI/CD and a zero downtime deploy.
You get
A live product. The same approach moved Zingbizz's legacy systems with 99.9% uptime.
- 04
Run
Monitoring is wired in before launch, not after the first outage.
You get
Grafana, Prometheus and Sentry watching, so problems surface before users report them.
Under the hood
What happens when someone taps your app.
You tap “Book a call” on the app.
- You tap “Book a call” on the app.
- The request reaches the web server. Next.js renders the page on the server, so it is fast and Google can read it.
- The NestJS API checks who you are and what you are allowed to do.
- The database saves the booking. Queries are tuned: on Vybn they got 40% faster.
- The answer comes back in a blink, and your screen says Booked.
- Every step is watched by Grafana and Sentry, so problems show up before users report them.

About
Engineer first. Always shipping.
I am Sundar Prakash P, a software engineer in Chennai. I have worked at product companies building full stack apps, mobile products and automated test infrastructure.
I like work where the details decide the outcome: a deploy that never drops a request, a sync that never loses a record, a page that is fast enough to rank.
