What I'm looking for

I'm looking to build scalable, AI-enabled product workflows across full-stack and cloud systems, owning features end-to-end and collaborating closely with cross-functional engineering teams.

I've built AI-powered logistics software at Isaiah Logistics, replacing a costly third-party tool with a Next.js and Supabase platform. I integrated Claude to parse inconsistent bills of lading, suggest routes, and flag scheduling conflicts.

At Tiltek Technologies, I helped re-architect a job-hunting platform into a custom Angular, Node.js, and AWS SPA, cutting server and storage costs by 65% and supporting 500,000+ weekly active users. I also built a real-time SMS voting platform using React, Spring Boot, and Kafka that sustained 1,000+ requests per second, peaking above 3,000 with zero downtime during a live broadcast.

I've contributed full-stack product work at DadoHR, integrating Google Calendar and Slack into its HR onboarding platform, and helped modernize a poker tournament application at Mereb Technologies into gRPC-based microservices. I also built a hands-free trivia mechanic using Google FaceMesh and real-time face tracking.

I work across React, Next.js, Node.js, Spring Boot, cloud infrastructure, and AI development tooling, and I'm an AWS Certified Solutions Architect.
