Open to remote senior engineering roles

I build systems that reach millions — reliably, and at scale.

Senior Full Stack & Backend Engineer with 5 years at Eventbrite and ServiceNow. I specialise in notification, growth and platform engineering — the infrastructure that quietly moves the numbers that matter.

A 90-second hello

Rather hear it from me?

Resumes flatten people. In this short video I walk through how I think about engineering problems and what I'd bring to your team — the things a bullet list can't show.

About

Hi, I'm Prerna 👋

"I like the unglamorous engineering — the pipelines, the notification systems, the migrations — because that's usually where the real impact hides."

I'm a senior engineer based in Hyderabad who has spent the last five years building event-driven microservices, data pipelines, and notification systems at scale. At Eventbrite I owned the platform that talks to millions of users; at ServiceNow I built no-code tools that let non-engineers ship.

I care about pragmatic decisions — weighing scale, cost, performance and the messy reality of legacy systems — and I tend to be the person teammates come to during incidents and code reviews. I've mentored interns, authored ADRs, and led delivery across product, data and marketing engineering.

Right now I'm looking for a remote-first team where I can own meaningful backend or full-stack surface area and help move the numbers that matter.

Selected impact

Numbers I've moved

A few shipped results from Eventbrite and ServiceNow — the kind of work I'd love to do for your team.

80×

Notification throughput

Architected an event-driven marketing platform (Lambda, SQS, SNS, Kafka) and scaled notification throughput 80× by expanding campaign reach.

+27%

Paid orders

Designed 25+ A/B experiments (Statsig, Heap) on conversion-critical flows, driving a 27% lift in paid orders within three months.

80M+

Records migrated

Built ETL preference pipelines (Airflow, Snowflake, Glue) enabling a zero-downtime migration across 80M+ records.

~11M

Emails saved

Found and patched a critical unsubscription bug affecting ~11M quarterly emails, cutting bounce rates and erroneous sends.

65%

Faster recovery

Shipped real-time observability dashboards with anomaly detection, improving incident visibility 10× and reducing MTTR by 65%.

500+

Sites, zero eng

At ServiceNow, built a no-code Site Builder that scaled to 1,900 users and 500+ published sites with zero engineering dependency.

Beyond the code

Life outside the terminal

I think the best engineers are well-rounded humans. Here's what fills my weekends and keeps me curious.

✈️

Travelling

New cities, slow mornings, and the occasional missed train. Travel resets how I think — and gives me far too many camera-roll folders to organise.

💃

Dancing

My favourite way to switch the analytical brain off. Whether it's a class or the kitchen at 11pm, if there's a good beat I'm in.

🍜

Exploring food

Equal parts hobby and personality trait. I'll travel across a city for a dish someone swears by — and I keep a running list of the best ones.

Writing

Notes & half-thoughts

Occasional writing on engineering, building things, and the stuff in between. Click to read.

Get in touch

Let's build something good together.

I'm open to remote-first senior engineering roles. If you're hiring — or just want to say hi — I'd love to hear from you.
