Software Engineer · Boston, MA

I build production backend systems in Java and Spring, extended with cloud-native infrastructure and applied AI when the problem calls for it.

About

I’m a software engineer with two-plus years of production experience building backend systems that have to actually hold up, race-condition-free under thousands of concurrent users, fast under batch loads of fifty thousand transactions a day, and reliable enough for insurance and telecom workloads where downtime has real consequences. My day-to-day is Java and Spring, but the projects I’ve shipped have pulled me deep into AWS, Kubernetes, and applied AI alongside the core backend work.

The work I’m most drawn to lives at the seam between backend engineering and the systems around it, figuring out how a service should be structured to stay correct under load, where caching belongs, when a problem actually needs an AI layer versus when it just needs better data modeling. I care about systems that are still working, and still understandable even long after I’ve moved on.

Right now I’m finishing my MS in Software Engineering Systems at Northeastern, graduating December 2026, and open to full-time Software Engineering roles starting 2026 in backend, cloud, or applied AI.

Outside of engineering, I enjoy exploring different cuisines and playing cricket.

PayFlow Payment Processing PlatformPersonal Project · 202684 testsBuilt a from-scratch payment backend that models the full payment lifecycle as a finite state machine over an immutable double-entry ledger, guaranteeing under concurrent load that a balance never goes negative, a payment is never charged twice even across a crash mid-authorization, and a scheduled job never runs twice across replicas, verified by 84 tests against real PostgreSQL and Redis.Java 21Spring Boot 4PostgreSQL 17Redis 8Spring BatchResilience4jShedLock
Autonomous SRE Agent on KubernetesRibbon Communications · 2025< 30sDesigned and prototyped an autonomous reliability agent that detects production failures across Kubernetes clusters in under thirty seconds, replacing reactive log-correlation workflows with real-time Kubernetes watch streams, Prometheus metrics, and ML-based classification.PythonKubernetesPrometheusMicrosoft AIOpsLabDockerML
