Backend engineering focusJava, Spring Boot, Kafka, Kubernetes

Vishal Kesharwani

Backend Developer | MIT AOE '26 | Java, Spring Boot, Kafka, Kubernetes, AWS

I build backend platforms that are reliable, scalable, and worth trusting in production.

I'm a Computer Engineering student at MIT Academy of Engineering with internship experience in Java backend development and cloud engineering. I build event-driven services on Kafka, run them on Kubernetes with real observability, and want to own the quality of the whole delivery path.

Who I am

About

Backend-firstProduct-minded

I like building software that is structured, secure, and easy to hand over to the next developer.

My resume centers on Java backend engineering: Spring Boot, Spring Security, PostgreSQL, and event-driven services on Kafka, shipped to Kubernetes through Docker, ArgoCD, and Terraform. I care about the boring but important details: clean service boundaries, debounced workflows, documented APIs, real observability, and deployments that can be repeated without surprises.

Cloud-Native Job Application Tracker

Event-driven observability platform built from three independent Spring Boot microservices that communicate only through Kafka events, deployed to Kubernetes through ArgoCD GitOps with a full Grafana LGTM observability stack.

  • Three services, zero direct service-to-service calls
  • Redis read-model rebuildable by replaying the event log
  • Prometheus, Loki, and Tempo traces via OpenTelemetry
  • ArgoCD GitOps reconciliation with Terraform IaC for EKS

Try it yourself

Cloud Lab

Playable sandbox

I like cloud work to feel like a small terminal game.

Type a command, watch the output, and walk the path from local code to Docker, Kubernetes, and a GitOps deployment.

How to use

Type a command and see what happens next.

Goal

Make deployment feel logical and hands-on.

Try these commands

Mini quest

0/3

Inspect the environment

Run ls or pwd to see the three services.

Build the container

Use docker build . to package a service.

Ship it to the cluster

Try kubectl get pods, argocd sync, or deploy.
