Make complexity obey.

From high-throughput logistics platforms to real-time collaborative worlds, I operate where product velocity meets resilient systems engineering. I work where product velocity meets resilient systems engineering — from high-throughput logistics to real-time collaborative worlds.

Full-Stack Engineer (PERN/MERN) building scalable logistics and SaaS platforms with React.js, Next.js, and Node.js. Specializes in event-driven microservices, secure authentication, and CI/CD-driven delivery — cutting processing time by 45% and boosting query performance by 25%.

01
01 / ARCHITECTURE

Event-Driven & Decoupled

Microservices orchestrated via RabbitMQ & Kafka, built to scale independently and recover gracefully.

02
02 / REAL-TIME

Sub-100ms State Sync

Low-latency WebSockets, WebRTC meshes, and delta compression for responsive multi-user collaboration.

03
03 / PERFORMANCE

Production Measurable Impact

Query optimization, zero-config serverless PostgreSQL layers, and memoized front-end rendering pipelines.

06Dossier · Forged the hard wayCHEM → BIZ → CS

Chemistry. Combat. Code.

An intentional, unconventional path: experimental chemistry → marketing and user-acquisition economics → Master of Computer Applications. Each layer compounds — rigor, empathy, systems.

“The interdisciplinary edge is real: chemistry taught me to experiment, business taught me to listen, CS taught me to scale.”
