Senior Lead Developer

Caitlyn Jules Tayco (CJ)

Building reliable web platforms and accelerating delivery with practical AI workflows.

Senior lead developer with 6+ years designing and shipping production web platforms, from meal delivery subscriptions and multi-tenant inventory systems to fintech accounting software. Deep Laravel expertise, with full-stack range across Vue.js, React/Next.js, Python/FastAPI, WordPress, MySQL, and MongoDB.

At Vyde Tax and Accounting, I grew from developer to team lead, architected a Laravel banking microservice used across Vyde products, and led squads delivering the accounting platform and client portal.

I use AI tools pragmatically to improve delivery speed and code quality, with clear workflows, human review, and testing before merge. Open to senior engineering and tech-lead roles where I can own systems end-to-end.

Based in Davao City, Philippines

I use AI tools to accelerate delivery while maintaining engineering standards through skills, rules, and verification gates.
