I’m a Senior Full-Stack Developer with 7 years of experience, passionate about both front-end and back-end development. I specialize in building robust, scalable solutions using JS/TS, React, Node.js, and Google Cloud Platform (GCP). I'm also certified as a Professional Cloud Architect by Google Cloud, so building and improving cloud environments is part of my job.
My current role is Tech Lead in a company of the music industry, building the developer platform of an AI product. I’ve also mentored developers outside of this role, successfully guiding them through technical challenges and career growth on platforms like Codementor and in past jobs.
I’m highly skilled in:
- Debugging and solving complex issues
- Teaching core programming concepts, especially in JavaScript, Node.js, and React
- Code reviews focused on quality and best practices
- API design and integration
- PostgreSQL and database management
Whether you're looking to solve specific coding problems, improve your workflow, or develop your technical skills, I’m here to help. My approach is hands-on, patient, and tailored to individual needs, always aiming for growth and success.
Hi there! I’m Ferenck Vargas, an experienced backend software engineer and tech lead with over 10 years of industry expertise in API development, payment integrations, scalable architecture, and team leadership.
As a former college lecturer and mentor, I have a passion for guiding developers to unlock their full potential. I specialize in:
Revitalizing APIs and building high-performance backend systems.
Implementing payment integrations like Stripe to optimize business workflows.
Leading engineering teams to deliver scalable and reliable solutions.
Whether you're a beginner looking to understand software fundamentals or an experienced developer needing guidance on complex backend challenges, I’m here to help. Let’s tackle your projects together!
Full-stack engineer with 15+ years building products at early-stage startups, from founding engineer at Replo (YC S21) to leading technical projects across agencies and e-commerce companies. Strong focus on React, performance optimization, and headless architecture. I've taken projects from zero to production across many different technical domains and enjoy the fast-paced nature of startups where you need to wear multiple hats and take real ownership.
I've been building web applications for over 14 years, from the jQuery and PHP days all the way to where we are now with React, Next.js, Remix, and Supabase. These days, I spend more time orchestrating AI tools than writing code line by line, and I think that's where the industry is heading.
My current workflow is heavily AI-augmented. I use agentic coding tools, build custom MCP servers to extend what AI can do, and create automation skills that handle everything from ticket management to spinning up parallel git worktrees for multi-ticket development. I've also built workflows for automated code review and implementation planning. The shift from writing every line myself to directing AI agents and reviewing their output has been a real multiplier. I'm shipping faster than ever while focusing on architecture, system design, and making sure things actually work.
My background spans the full stack: PHP, MySQL, and Vue.js on the server-side end, and modern TypeScript, React, Next.js, Remix, and Supabase on the current end. I've worked with e-commerce integrations and AI agent orchestration frameworks. I care about clean architecture, pragmatic tech choices, and building things that solve actual problems for real users.
Based in Davao City, Philippines.
Yes, this section was written with AI. But I reviewed, edited, and approved it. If that bothers you, just know that I build software the same way now, and it ships faster than ever.
