About
I'm AJ.I build things.
I'm Agasthya Joshi, AJ for short. I'm a founder and builder based in Nottingham, studying Cyber Security at De Montfort University.
I run two businesses of my own. Revti.ai is an AI front office: agents that answer and make calls, reply on WhatsApp, SMS and web chat, and book appointments. Pact books pre-qualified clients in with UK advisers.
Clients tell me what they want and I build all of it: the brand, the website, the software and the AI behind it. KK Tax asked for a website and got a whole new brand. Pact started as an adviser's idea and is now a marketplace with web, Mac, Windows and phone apps.
I grew up around my family's business, Royal Chai, and built its websites for five years. Before that I worked at McDonald's through school.

Cyber security
Secure bydefault.
Most builders add security at the end, if at all. I study it, and I build it in from the first line.
01Studied, not guessed
BSc Cyber Security at De Montfort University: SOC work, malware analysis and threat intelligence, after a year of Cyber Security at Nottingham Trent.
02Built into every project
Pact runs on 74 row-level security policies, so each adviser and client can only ever see their own data.
03Offered as a service
I review websites and apps for login, data access, secrets and exposed endpoints, then fix what I find if you want me to.
