## Bio

Hey! I'm Harshit — a full-stack dev who builds web apps for real users and tinkers with LLM features on the side. Sometimes I disappear into C++ to break my own binaries on purpose. I care about shipping fast, learning in public, and giving back to the open-source communities I lean on.

Lately I've been living in two worlds: shipping full-stack products that have to work in production, and wiring up Gen AI features that have to actually be useful. The boring parts matter most to me — clean APIs, fast feedback loops, type safety, code my future self can actually read.

Outside of work I'm usually reading, writing, or poking at something new — lately that's meant C++ obfuscators and anti-reverse-engineering tooling, because someone has to. Open source has given me a career; I try to send PRs back whenever I can.

## Services

- **Full-stack web apps** — End-to-end web products, from React frontends to the database. Shipped in weeks, not quarters — solo, no agency middleman.
- **App security & anti-reverse engineering** — C++ obfuscation, anti-tamper, anti-debug, packing. If your binary is your moat, I'll make it harder to clone.
- **Script & low-level obfuscation** — JavaScript, TypeScript, Lua, Python — anything that runs in a browser or interpreter. Source unreadable, runtime behavior identical.
- **Code review & consulting** — Architecture audits, second opinions, or pair sessions when your team is stuck. One call usually beats a week of guessing.
- **Performance optimization & profiling** — Found the bottleneck nobody else could. Profile, fix, and benchmark until the numbers actually move.
- **Gen AI products & smart automation** — LLM-powered features, RAG pipelines, agent workflows, the boring glue around them. Production, not demos.

## FAQ

### Who is Harshit Katheria?

I'm a full-stack developer who builds web apps for real users, wires up AI features that have to actually work, and dabbles in C++ obfuscation on weekends for fun. Solo operator, fast turnaround, I take notes in public.

### What services does Harshit offer?

Six things, mostly: full-stack web apps, C++ app security and anti-reverse engineering, script and low-level obfuscation, code review and consulting, performance optimization, and Gen AI products with smart automation. If your problem doesn't fit one of these, ask anyway.

### How fast does Harshit ship?

Weeks, not quarters. I'm solo, which means no agency middleman, no project manager translating your Slack message into three internal meetings. Most full-stack MVPs land in 2-6 weeks depending on scope. Bigger stuff is a conversation.

### Where is Harshit based?

India, working remote with clients mostly in the US and EU. I'm flexible on timezone overlap — most weeks that means 4-6 hours of synchronous time, plenty for shipping work that doesn't need a meeting.
