Experience

Principal-Level Platform & Systems Engineering

Strategic architecture. Hands-on execution. Production-grade systems. I operate at the intersection of architecture, performance, and implementation. As a Principal Engineer I stay deeply involved in the code, especially in the most critical parts.

My work spans:

Architectural direction
Core system design
Performance-critical implementation
Cross-team technical alignment

Enterprise Backend, Performance & Resilience

Hands-on experience designing and implementing backend systems for large user bases with strict reliability and performance requirements.

Designing and coding Spring Boot microservices
Building distributed APIs (REST & GraphQL)
Event-driven workflows, high-throughput data access
Refactoring legacy systems into scalable modules
Eliminating N+1 queries, layered caching (Redis, in-memory)
Idempotent APIs, retry and backoff, circuit breakers
Observability-first design, backward compatibility

Mobile & Cross-Platform Engineering

Full-stack depth across native and cross-platform:

iOS Native (Swift / SwiftUI)
Android Native (Kotlin / Jetpack Compose)
React Native
Clean architectural layering, performance-aware UI
Shared API contracts, telemetry, CI/CD for mobile

About

I am a Principal-level Software Engineer with over a decade of hands-on experience building, scaling, and evolving production-grade systems across enterprise, government, and high-growth environments.

My expertise centers around Java, Spring Boot, and distributed microservices architecture, with a strong emphasis on high-performance system design and long-term maintainability. Throughout my career, I have designed and implemented backend platforms that power large-scale applications serving substantial daily traffic, while maintaining strict reliability and availability standards.

I specialize in architecting scalable, event-driven systems built on cloud-native foundations. My work spans:

Designing and implementing microservices ecosystems

Building high-throughput APIs (REST & GraphQL)

Engineering distributed systems with resilience and observability in mind

Implementing performance optimization and caching strategies

Establishing architectural governance and best practices

Beyond system design, I remain deeply hands-on in critical implementation layers, especially where performance, scalability, and architectural integrity matter most.

I have contributed to projects across education, government, smart city infrastructure, and enterprise sectors, including cloud-based GIS platforms and large-scale data-driven applications. My approach combines systems thinking with execution discipline ensuring that architecture is not only visionary, but operationally sound.

I hold a Master's degree in Computer Science and a Bachelor's degree in Computer Engineering. Based in New York City, I continuously explore emerging technologies, distributed architecture patterns, and performance engineering techniques to build robust systems that scale predictably and endure over time.
