I BUILD SYSTEMSTHAT HOLD UP.
Backend engineering grounded in concurrency, idempotency, observability, and proof. I turn complex workflows into reliable products—and benchmark the result.

01 / Experience
IMPACT, NOT ACTIVITY.
One internship. Four production-minded improvements. Every point tied to a visible engineering outcome.
Codec Technologies
Java Developer Intern
Improved the speed, consistency, and extensibility of Spring-based application workflows through concurrency, caching, centralized error handling, and design patterns.
- ~40%faster report generation by parallelizing data processing pipelines with Java ExecutorService.
- 20+REST endpoints standardized with Spring @ControllerAdvice and centralized JSON error responses, eliminating redundant try-catch blocks.
- ~25%faster future feature implementation after refactoring monolithic validation logic with the Strategy Design Pattern.
- ~30%lower average API latency by caching high-frequency queries with Spring Cache and reducing database throughput pressure.

PROOF IN PRODUCTION SHAPES.
Two full-stack platforms spanning concurrency, real-time state, and reliable HTTP delivery.
01Real-time queue operations
LinePilot
A Dockerized real-time queue platform built for safe concurrent staff actions and live customer updates.
- Built a Dockerized real-time queue management platform with separate customer, staff, and administrator workflows, exposed through Spring Boot REST APIs and a React + TypeScript frontend.
- Prevented duplicate concurrent claims with PostgreSQL FOR UPDATE SKIP LOCKED, transactional state transitions, and uniqueness constraints, recording 0 duplicate assignments and 0 failures across 120 call-next requests in three local benchmark runs.
- Streamed committed queue snapshots to five connected Server-Sent Events (SSE) clients per run with 62 ms median and 84.5 ms p95 update latency across 300 measured samples.
0duplicate assignments across 120 requests
02Reliable webhook delivery
SignalDock
An idempotent event and webhook delivery platform designed to make retries, signatures, and failure states observable.
- Built a modular monolith for registering receivers, accepting idempotent events, and tracking signed HTTP delivery attempts with retries, backed by Flyway-managed PostgreSQL schemas.
- Implemented database-backed idempotency and queue processing that collapsed 100 concurrent same-key requests into one event and verified a three-attempt HTTP 503 retry path ending in a persisted DEAD state.
- Completed 3,000 of 3,000 success-path deliveries with zero terminal failures across three local Docker runs, achieving 92.1 deliveries per second median throughput and outbound-attempt p95 latency of 3.1–4.5 ms.

04 / About
DISCIPLINED BY DESIGN. CURIOUS BY DEFAULT.
I’m a software engineer specializing in Java, Spring Boot, and full-stack application development, with hands-on experience building secure, scalable systems and REST APIs.
My work spans real-time queue management and reliable webhook delivery using Spring Boot, PostgreSQL, React, TypeScript, and Docker. I pair data structures, system design, and concurrency fundamentals with a disciplined, results-oriented approach to backend engineering.
