One Dev, One Launch: How I Built My Web App and Extension Solo in 2025 with AI

Hi devs ๐Ÿ‘‹

I wanted to share my journey of building and launching a real, working web product entirely solo in 2025 โ€” including backend, frontend, deployment, and even a Chrome extension.

If youโ€™ve ever dreamed of creating your own product but felt overwhelmed, maybe this post will give you a push. AI has changed the game โ€” and what used to take a team can now be done by one developer.


๐Ÿ’ป My Background

Iโ€™ve worked as a Java backend engineer for over a decade across industries like telecom, travel, music, and insurance. But I always had the itch to build something of my own โ€” even something small, as long as I could call it mine.

I actually tried once, eight years ago. It didnโ€™t work out. I lacked motivation, frontend skills, and time. It felt like too much to handle alone.


โšก Enter AI

Then came ChatGPT and similar tools.

For the first time, I felt like I didnโ€™t need to master everything. I could focus on my backend strengths โ€” and let AI help with UI, DevOps, and even Chrome APIs I had no experience with.


๐Ÿš€ Building the Product

About five months ago, I committed to building something real.

  • โœ… Backend: Spring Boot
  • โœ… Frontend: Vue.js
  • โœ… Chrome Extension: built from scratch with help from AI
  • โœ… All done solo

Creating the extension was the biggest challenge. I had zero experience with browser APIs โ€” but with AI as my co-pilot, I got it working.


๐Ÿ”ง DevOps (My Old Nemesis)

I used to dread DevOps. But this time, I powered through:

  • Deployed backend to AWS EC2
  • Hosted frontend via Nginx
  • Used AWS RDS for database
  • Dockerized everything, orchestrated with Docker Swarm
  • Set up backups, SSL, domain config, and email

In the past, this would have taken me weeks. With the help of AI, it took a few days.


๐Ÿ’ก Key Takeaway

In 2025, itโ€™s entirely possible to build and ship a real product solo.

If you're a developer with an idea but think โ€œI donโ€™t have timeโ€ or โ€œI canโ€™t do it allโ€ โ€” youโ€™re not alone. I felt that way for years.

But AI has leveled the playing field. You donโ€™t need to know it all anymore. You just need to start.


๐Ÿ”— What I Built

Hereโ€™s the product I launched:

Itโ€™s a platform that lets you:

  • See ratings and reviews of websites right inside your browser
  • Submit your own feedback
  • Instantly assess trustworthiness of a site

It works via a Chrome extension and acts as a social feedback layer for the internet.

Iโ€™d love to hear your feedback โ€” itโ€™s still evolving!
