What I've built, and why it mattered

A security system that can tell when a login looks suspicious — like someone signing in from two countries within an hour of each other.

The problem

Most login systems only check a password. They don't notice when a login pattern itself looks risky.

What I built

An authentication layer that scores how risky each login attempt looks in real time — including detecting physically impossible travel between logins — while keeping each customer's data isolated and encrypted.

Impact

Currently in development; designed from the ground up for multi-tenant companies that need bank-grade login security without building it themselves.

A project-management tool built for solo freelancers, with a real-time drag-and-drop task board.

The problem

Freelancers juggling multiple clients need a lightweight way to track work, invoice clients, and stay organized without enterprise software overhead.

What I built

A full product with real-time task boards, automatic PDF invoices, and email delivery — engineered so the board stays fast even with a lot of dragging and reordering, and so users never get logged out unexpectedly.

Impact

Cut the technical overhead of reordering tasks by more than 90%, and eliminated a whole class of random logout bugs that are common in apps like this.

Turns a rough business idea into a clear technical plan — for founders who aren't engineers.

The problem

Non-technical founders often can't communicate what they want to build in terms a development team can act on.

What I built

An AI-guided tool that asks the right questions, then produces a structured technical blueprint and database plan in plain language, with safeguards so the AI can't get stuck in a loop or return unusable output.

Impact

Reduced repeat-query response time from about 4 seconds to 15 milliseconds by caching prior AI responses, and cut token costs on repeat use to zero.

Lets a company's employees ask plain-English questions about internal policies and get accurate, trustworthy answers — instead of digging through PDFs.

The problem

Companies bury important rules in long policy documents that employees rarely read carefully, and generic AI chatbots tend to make things up when asked about specifics.

What I built

A secure platform where each company's data is kept completely separate from every other company's, with a search system that combines two different techniques to find the right answer instead of guessing.

Impact

Achieved a perfect accuracy score on a custom testing system built specifically to catch AI mistakes, meaning the answers it gives can actually be trusted.

A ready-made login and session system other applications can drop in, instead of building authentication from scratch.

The problem

Every new product needs login and session handling, and building it securely from scratch is easy to get wrong.

What I built

A standalone authentication service handling secure sessions and route protection, built to be reused across projects.

Impact

Used as the authentication foundation for his other projects.
