Full Stack Developer

[email protected] February 26, 2026

Dear Hiring Manager,

I am writing to express my strong interest in the Full Stack Developer position at your company. With extensive experience building production-grade web applications using React, Next.js, Node.js, and modern cloud infrastructure, I am confident in my ability to contribute meaningfully to your engineering team from day one.

In my current role as a Freelancer, I have architected and coded two complex, real-time web applications that demonstrate the full breadth of my technical capabilities. My Twitter/X clone features real-time feeds powered by WebSockets, @mentions, #hashtags, and a reverse-chronological timeline — all built with React and Supabase. My Slack clone implements public and private channels, direct messaging, file sharing, full-text search, and Stripe-integrated subscription billing. Both applications are deployed on Vercel with CI/CD pipelines and maintain 99.9% uptime.

What sets me apart is my end-to-end ownership mentality. I don't just write code — I design user experiences with Figma, architect databases with Supabase and PostgreSQL, implement secure authentication with Row Level Security, integrate payment systems with Stripe, and deploy with automated CI/CD on Vercel. This full-stack fluency allows me to move fast, ship independently, and communicate effectively across product, design, and engineering teams.

I am particularly drawn to remote-first companies that value async communication, autonomy, and shipping velocity. Having worked remotely throughout my career, I have developed strong self-direction, clear written communication, and the discipline to deliver consistently without oversight. I thrive in environments where engineers are trusted to own their work end-to-end.

My technical stack — React, Next.js, Node.js, TypeScript, Supabase, Stripe, and Vercel — aligns closely with the modern tools that high-performing engineering teams rely on. I am eager to bring this expertise to your team and contribute to building products that users love.

I would welcome the opportunity to discuss how my experience and skills can benefit your organization. Thank you for considering my application. I look forward to hearing from you.

Sincerely,

Thomas Perdana
