Software we build and own, not just software we bill for.

Vocab — Vocabulary & IELTS Prep

Spaced repetition, AI mnemonics and quiz modes for serious vocabulary building.

Our own language-learning app: a React Native client on a FastAPI backend, with an SM-2 spaced-repetition engine and AI mnemonics generated on demand. Built for long-term retention rather than streak theatre, and the one product here with a full case study behind it.

What's included

• SM-2 spaced repetition
• AI-generated mnemonics
• Multi-mode quizzes
• Streaks, heatmaps and leaderboards
• Freemium and premium tiers

Built with

• React Native
• FastAPI
• PostgreSQL
• Redis
• Celery
• Groq

Gym & Fitness

Member check-in, class scheduling and recurring billing for a single-site gym.

A gym operations app we are building in-house: members book and check into classes from their phone, staff run the timetable and the membership plans from the same system. Scoped for independent studios rather than multi-site chains.

What's included

• Member profiles and check-in
• Class timetable and booking
• Membership plans
• Recurring billing
• Trainer schedules
• Attendance reporting

Pregnancy & Cycle Tracker

Cycle and pregnancy tracking that keeps the data on the device by default.

A tracking app for cycles and pregnancy, designed privacy-first: predictions and reminders are computed on the device, and sync is an explicit opt-in. Still in development — we are being deliberate about which health data is worth storing at all.

What's included

• Cycle logging and predictions
• Week-by-week pregnancy timeline
• Symptom and mood tracking
• Reminders
• On-device data with opt-in sync

School Management

Admissions, attendance, results and fees in one system teachers actually use.

A custom-built school management system covering the daily administrative loop: enrolment, class and section allocation, attendance, exams and results, and fee collection. Built for a real institution and configured per school, rather than sold as a fixed plan.

What's included

• Student enrolment and records
• Classes, sections and timetable
• Attendance
• Exams, grading and report cards
• Fee collection and receipts
• Parent and teacher accounts

Litigation Management

Cases, hearings, deadlines and documents for a working law practice.

A custom-built case management system for litigation practices: matters, parties, hearing dates, and the document trail attached to each. Deadlines are the point — the system exists so that a hearing date is never held only in one person’s memory.

What's included

• Case and matter records
• Parties and counsel
• Hearing calendar
• Deadline and limitation reminders
• Case documents and filings
• Time and billing notes

Document Management

Versioned document storage with permissions, approvals and an audit trail.

A custom-built DMS for organisations that need to know who changed what and when: structured folders and metadata, version history, role-based access, and a review step before a document becomes the current one. Full-text search across the archive.

What's included

• Structured folders and metadata
• Version history
• Role-based permissions
• Review and approval workflow
• Full-text search
• Audit trail

Hotel ERP

Reservations, folios, rooms and guests on a Frappe/ERPNext foundation.

A hotel property-management build on Frappe/ERPNext: a reservation opens a guest folio, room charges post per night, and payments settle against the balance due. Because it sits on ERPNext, accounting and inventory are already next door instead of a separate integration.

What's included

• Reservations
• Guest folio with per-night charges
• Room inventory and rates
• Guest profiles
• Payments and balance due
• ERPNext accounting and inventory

Built with

• Frappe
• ERPNext
• Python
• MariaDB

Swiss QR-bill invoices, camt.054 bank reconciliation, and double-entry VAT books.

Business ERP

The generic back office: sales, purchasing, inventory and accounts.

Our general-purpose ERP configuration for small and mid-size businesses that have outgrown spreadsheets — quote to invoice, purchase to stock, and the ledger behind both. Distinct from the Hotel ERP, which adds a property front desk on top of the same foundation.

What's included

• Quotes, orders and invoices
• Purchasing and suppliers
• Inventory and warehouses
• Accounts and ledgers
• Customer and supplier records
• Reporting dashboards

Invoicing & Billing

Invoices, recurring billing and payment chasing for small teams.

• Invoice and quote builder
• Recurring invoices
• Tax and multi-currency
