What I'm looking for

I’m looking to own end-to-end features in a team that values measurable outcomes—conversion improvements, predictive insights, and automation. I want to blend full-stack development with AI workflow integration and real business dashboards.

I’m a full-stack developer with nearly two decades of experience across telecom systems engineering, banking automation, payment platforms, e-commerce, and AI engineering. I’m drawn to building systems that solve “technically difficult for their time” problems—like cross-carrier unlimited messaging built on multiple GSM modems.

In recent work, I’ve been expanding from web development into AI engineering and automation. I integrate AI tools into web development workflows and build custom AI-driven automations while staying comfortable owning features end-to-end—from front-end UI through back-end logic to data and reporting.

At Bioptimizers.com, I build and maintain marketing landing pages for a custom e-commerce shop platform using JavaScript, HTML, CSS, and Vite. I designed and shipped the Side Cart feature and a Shopify-style promotional offer system, and I built A/B test variant pages in Convert to support conversion-rate optimization experiments.

I also design BI dashboards and predictive analytics—using Python for data cleanup and computation, plus OLS regression and Pearson correlation to model and forecast performance trends. My earlier experience includes building payment platform integrations with ASP.NET/WCF at Bayad Center, production POS bug-fixing with VB.NET at Fujitsu Philippines, and automated loan report workflows with Crystal Reports at EastWest Bank.
