Rewriting a Legacy VB6 App Solo — 4 Years In, Still Going

Hi Devs 👋

I’m a solo developer based in the UK, and I’ve been working on a long-term rewrite of a legacy VB6 application into a modern stack. It’s been over four years of deep refactoring, architecture redesign, and plenty of reverse-engineering—definitely a labor of love (and sometimes frustration!).

The original app was a VB6 desktop tool used in Trading, and I’ve been migrating it to [C#/WPF/.NET/etc.]. Along the way, I’ve wrestled with technical debt, shifting requirements, and the occasional existential dread that comes with solo dev work.

I’m posting here to connect with others who’ve tackled legacy migrations or long solo projects. I’d especially love to hear from devs in tech who’ve navigated similar challenges—whether it’s burnout, imposter syndrome, or just the grind of keeping momentum alive.

If you’ve ever rewritten something that felt like a beast, I’d love to hear your story. And if you have tips for staying motivated or knowing when to pivot, I’m all ears.

Looking forward to learning from you all and hopefully sharing a few war stories of my own!

Cheers,
