Full-Stack Engineer | React, Node.js, Python, TS
Cavite
I'm Mikas, a full-stack engineer with over 3.5 years of experience building web apps, PWAs, and browser extensions. My main stack includes React, Svelte/SvelteKit, Node.js, Python (Django), and PostgreSQL/MongoDB. What sets me apart is how I approach a codebase: I try to break things before users do. I look for edge cases where a system might snap under load, and I use automated testing (Playwright, Jest, Cypress) to make sure those fixes remain fixes. Over the past few years at Codefrost, I've worked on data visualization platforms, browser extensions, mobile PWAs, and automated web scraping/AI analysis pipelines (extracting and processing e-commerce/Amazon data using Python). I'm comfortable working asynchronously, writing clear documentation, and overlapping with US or international timezones. I have a reliable fiber setup and can jump into a project without needing much hand-holding.
