About this gig
Hi! I'm a Product Engineer specializing in SaaS development and workflow automation, with 3+ years of experience and 200+ browser extensions shipped across eCommerce, productivity, and B2B SaaS.
I treat every extension as a SaaS product in its own right, production-grade, scalable, and reliable under real usage, not just functional in a demo. Whether it's a standalone tool or tied into a larger platform, it gets the same engineering rigor as any SaaS build.
What I Offer:
- Custom extensions built for your exact website or workflow
- Reliable, maintainable web scraping tools
- Automation for form-filling and repetitive tasks
- Extensions that integrate with SaaS platforms, APIs, and backend systems
- Full lifecycle: manifest migrations, store publishing, maintenance
Why Work With Me:
- Full-stack expertise across modern frontend and backend
- Experience integrating third-party platforms, payments, and cloud services
- Works across Chrome, Firefox, and Edge, including manifest migrations
- Track record building tools that scale to real users
Have an idea? Let's talk it through and I'll tell you honestly if I'm the right fit.
Looking forward to working with you!

FAQ
How long does it take to build a Chrome extension?
Depends on complexity. Simple tools (form-filling, filtering) usually take 3-5 days. Extensions with scraping, backend integrations, or SaaS-tier features take 1-3 weeks. I'll give you a firm timeline after we scope the requirements.
Can you publish it to the Chrome Web Store for me?
Yes. I can handle the full submission, including store listing assets, privacy policy, and review requirements. If you already have a developer account, I'll publish under it; otherwise I can guide you through setup.
Do you provide support after delivery?
Yes, all gigs include a bug-fix window post-delivery. Ongoing maintenance, feature additions, or ownership handoff support are available separately if you need continued updates after launch.
Can the extension also work on Firefox or Edge?
Yes. I build with cross-browser compatibility in mind and can adapt a Chrome extension for Firefox and Edge, including handling their manifest and API differences. Let me know upfront if multi-browser support is required.
What do you need from me to get started?
A clear description of the functionality, the target website(s) or platform, and any design/branding preferences. If it involves an API or backend, share docs or access details so I can scope integration accurately.
