About

Backend engineer building
scalable, high-throughput systems.

I'm a Graduate CS student at SUNY New Paltz with 3+ years of professional backend engineering experience. I've designed distributed Java services, built 100+ REST API endpoints for enterprise transactional workflows, and driven a 30% improvement in system performance through backend optimization.

My core stack is Java · Spring Boot · REST APIs · MySQL — complemented by Node.js, React, and MongoDB for full-stack work. I'm drawn to systems where correctness, scalability, and low latency are non-negotiable — exactly the problems found in high-volume financial trading infrastructure.

As a Teaching Assistant for Data Structures & Algorithms, I'm equally comfortable debugging complex systems as communicating clearly across teams.

Volunteer Work

Community & Advocacy Support

A network of aligned organizations and portals established over 25 years ago by a single owner. I took over the maintenance and modernization of these live production websites to preserve their digital legacy.

Advocacy

🦌

C.A.S.H. (Committee To Abolish Sport Hunting)

Wildlife Protection Advocacy

Supported the online infrastructure and digital outreach for an established wildlife protection committee originally formed over two decades ago. I took over to modernize and maintain their CMS platform, ensuring high availability and seamless content management. My updates streamlined the process for publishing advocacy articles and managing memberships, keeping their decades-long mission active and engaging.

LOHV

League of Humane Voters

A national organization operating across all US states to mobilize public support for animal-friendly legislation. Upon taking ownership of their legacy systems, I modernized the core architecture to ensure robust site reliability. I mapped and repaired complex database queries written over 20 years ago, successfully preventing state-wide data loss and sustaining their high-traffic legislative event boards.

Wildlife Watch

Environmental Rescue Network

Empowered a critical direct-aid environmental network dedicated to rescuing injured and orphaned wildlife. The original platform was built in the early internet era; I successfully modernized and refactored twenty-five-year-old legacy directory structures to meet current web standards. This secured and optimized the central wildlife emergency hotline portal, bringing a crucial 90s-era life-saving network into the modern digital age.

Legacy SystemsPHPDNS Config

🏡

New Paltz Living

Student Property Portal

Maintained a vital regional property portal connecting college students with accessible off-campus housing. Inheriting an obsolete deployment, I rapidly diagnosed and resolved underlying server-level outages to minimize downtime during peak rental seasons. I entirely modernized the user interface and responsive markup to transition the site from a legacy desktop layout to a seamless, mobile-friendly user experience.

Saugerties Living

Regional Apartment Listings

Managed and stabilized a comprehensive digital portal for regional apartment listings, which had seen no updates since its inception over a decade ago. I spearheaded deep structural redesigns of the heavily fragmented legacy codebase, completely resolving broken pathways. I implemented strict modern cross-browser compatibility layers, guaranteeing that prospective tenants could correctly view floor plans across all modern devices.
