OpenLMS
A whole learning-management system standing up on plain PHP: catalog, enrolment, lessons, quizzes, certificates, chat and an AI tutor. The broadest thing I have built end to end on my own.
Finance Monster
Expenses, budgets, clients, quotes and invoices in one place, built to find out how much of a bookkeeping workflow a focused internal tool can actually cover.
Digital Nervous System
A projector-mode walkthrough of how air data, attitude and heading reference and the display units of a glass cockpit actually depend on each other.
Verifi
A concept for finding and verifying local businesses in Guyana, where the hard part is not the listing but proving the business is real.
AuditMaster Pro
A product concept for audit management: engagements, findings, evidence and reporting held together instead of scattered across spreadsheets.
Aviation Fuel Calc
A fuel uplift calculator that installs to the home screen and keeps working with no signal, which is the point when you are standing on an apron.
Multi-Aircraft Fuel Calculator
A target in pounds turned into the uplift per tank in litres for two aircraft by registration, with every refuel saved against the aircraft, the refueller and the time.
G1000 NXi Diagnostic Log
An eleven part briefing on the Garmin G1000 NXi, set in the panel’s own typography and advanced one data block at a time the way a cockpit readout releases information.
AME Swipe Study
Aircraft maintenance exam revision reshaped around the phone, one card and one thumb at a time, so it works in the gaps in a day rather than at a desk.
Gas Turbine Engine Quiz
A drill covering gas turbine theory, with the question bank written from real course material rather than pulled from a generic pool.
Jet Engine Knowledge Quiz
The companion drill on jet engine systems, running on the same engine as the gas turbine quiz to prove the format carried across a second syllabus.
Quiz Engine
The general purpose engine the subject specific drills above were built from. Kept around because it shows where the others started.
GPA Calculator
Grade point average for the AWT programme, with the weighting rules exposed in the interface so a student can check the arithmetic by hand and trust the result.
Ab-Initio Birthday Calendar
A class birthday calendar that renders a shareable card image for each person, generated in the browser with nothing sent to a server.
Tetris
A complete implementation written to find out whether the game loop, rotation and collision handling would stay readable inside a single file. They did.
These are independent builds rather than client work, kept online because the problems they solve are still real. Client and commercial projects are on the main portfolio.
