Proof, not promises
Case Studies & Engineering Notes
Real, verifiable builds and honest explainers on where AI actually helps in software delivery — including the enterprise work still under NDA.
ExamDesk: From Question Authoring to Practice Review
An interactive learning showcase connecting editable study material, a question bank, timed practice and answer explanations. Changes stay in your browser.

An original interactive operations prototype linking fictional restaurant orders, kitchen tickets, guest balances, stock and shift reports. No real payments or hotel data.

Explore an independent hospitality UI/UX concept connecting fictional room reservations, arrivals, housekeeping and restaurant tickets. No live hotel or payments.
GEO & SEO Page Audit: From URL to Actionable Checks
A working page-level audit tool that explains its scoring rules. Enter a public URL to inspect initial HTML and review SEO and GEO structure signals; no ranking or AI-citation promises.
Bulk Sign: One Placement Across Multiple PDFs
A browser-only portfolio prototype for positioning a visual mark on the last page of several PDFs, confirming the batch and exporting one ZIP. Not a certified digital signature service.

One connected workspace for a service team and its clients. Explore the complete proposal-to-delivery journey in a working browser demo — with fictional data, not a claimed client engagement.

An interactive business workflow demo that connects requested items, catalog data, pricing and human approval — without inventing prices or pretending to be a production SaaS.
Kang Ojol: Prototyping a Delivery App in the Browser
Try the customer and driver sides of a delivery workflow with pickup and drop-off locations, maps and order stages — clearly labeled as a demo, not a real courier network.
CV Job Matcher: Compare a CV Against a Real Listing
A separate job-search experiment: find an actual vacancy, compare its description against your CV, and get feedback specific to that listing — not a generic resume score.
JobAI Web: One Search Across Public Job Feeds
A live browser-based job discovery app that searches real listings from multiple public sources, shows where each job came from, and sends applicants to the original listing.

Most calorie trackers fail the moment logging becomes a chore. Kalori AI was built to remove that friction, and to prove out an AI-accelerated build process end to end.

OKX Pulse: A Real-Time Market Signal Dashboard
A personal trading dashboard built to test a market hypothesis rigorously without risking capital — not a signal-selling product, and it never places a real order.
Automating Ecommerce Operations at Scale
