Telegram bot that pushes homework prompts, collects submissions and surfaces them in a triage view for instructors. Replaces a chat-thread mess with structured tracking, without forcing learners onto a new platform.

highlights
  • Telegram Bot API
  • Submission triage view
  • No new platform for learners
03
Google Slides add-on

Math Slides

Google Slides add-on with branded template, layout catalogue and custom math font. Drops the cost of producing a maths deck from ~2 hours to ~15 minutes per deck while keeping brand integrity.

§ 03 / FLAGSHIP

GrassLMS
my own LMS

Open the live LMS

A teacher-first LMS built around a huge library of task types and flexible content tools. Teachers can author every screen by hand, or hand the wheel to AI — from a single intro lesson to a full personalised skill-practice set per student. Content always stays editable, so the teacher's craft is preserved.

Manual Author every screen yourself. Pick task types, write the brief, drop in your own assets. Full control.
AI · partial Hand AI a topic. Get one intro lesson back, fully editable. Use it as a starting point and polish.
AI · full personalisation Hand AI a skill gap per student. Get a complete practice set — intro · drills · project · quiz — adapted to the learner's level.
§ 04 / PORTFOLIO DEMOS

End-to-end demos
built as portfolio pieces

illustrative · synthetic clients

Built end-to-end on synthetic briefs so the full pipeline is visible — analysis, design, build, eval. Useful for showing how I think; not real client work. Real client programs are in § 01.

SDR onboarding synthetic brief

Custom mini-OS
for scenario-based onboarding

Self-contained shell · runs in any LMS or standalone

A custom mini-OS shell simulating the SDR's real workspace — Outreach, Gong, Salesforce, LinkedIn, Calendar, phone-dialler, Slack — each as its own draggable window on a desktop. Click any app to explore. Shows how scripted SCORM modules could drop a learner into a believable working environment instead of a slide deck.

Built end-to-end as portfolio pieces · single-LXD

Three tightly-scoped SCORM 1.2 packages built to show short-form delivery: security onboarding, call-centre de-escalation, ERP procurement rollout. Each: analysis brief → microlearning sequence → quizzes → SCORM package ready to drop into an LMS.

— D3 DEMO · fraud-review trainer
Payments risk desk synthetic

A fraud-review console
that trains near-endlessly

Procedural generator · runs standalone or in any LMS

A Stripe-Radar-style review console for payments risk: a queue of flagged transactions, a risk score, the rules that fired, and Approve / Decline / Escalate. Every shift is procedurally generated, and the model risk score is deliberately wrong on some cases — so the learner reads the signals instead of memorising. Instant feedback, a cost model, and an end-of-shift scorecard.

— D4 DEMO · branching voice scenario
Security awareness synthetic

A vishing call
you have to talk your way out of

Voiced branching scenario · runs standalone or in any LMS

An attacker phones you posing as IT Security and tries to talk you out of your MFA. The caller is voiced (audio), your replies branch the conversation, and he adapts his pressure — urgency, authority, threat. A real decision tree with four endings, a criterion-referenced objectives checklist, and a transcript-as-hint penalty (no transcript on a real call). Built for the moment awareness training usually skips.

— D5 DEMO · branching incident response
Payments risk, on-call synthetic

A live fraud attack
you run from the risk desk

Branching scenario · runs standalone or in any LMS

It's 2am, a card-testing attack is underway, and you're the only analyst on call. Your choices change how the attacker adapts — chase the IPs and the bot just rotates — and how the night ends: six outcomes across three live meters (fraud losses, customer impact, leadership trust). A real decision tree that teaches proportional response, not a quiz.
