The lab
This is where I show my work — live apps, things I'm building, and ideas on the horizon. No pitch deck. No fake roadmap. If it's here, I'm accountable to it.
Who
I'm Suman Kumar — 8+ years as a software engineer, Python coach to 900+ students worldwide, and someone who ships a new project every month when I can.
Lab rules
- Ship in public. Progress bars are honest. If I'm stuck, the bar moves slowly — that's the point.
- Discontinue honestly. Dead experiments stay in the archive. CoWIN checker is there on purpose.
- No accounts on this site. Waitlists are email-only. One confirmation, then silence until launch.
- Use what's live. Live apps link out immediately. This site is the map, not the product.
Follow along
I post builds on X and push code to GitHub. If an app has a waitlist, join it — I email once when it ships.
Work with me
I take on select freelance and contract engineering work — full-stack builds, automation, and AI integrations. Everything above is proof of how I build: in public, shipped, and maintained. If that looks like what you need, reach out.
