A selection of production systems built across healthcare, retail, fintech, and media.
Dance Studio SaaS · 2026
The problem
A dance studio management platform had complex billing logic — stacking benefits, multi-class discounts, family caps — with no automated test coverage and approximately 20 undiscovered bugs.
What we built
Audited and rebuilt the payment system using Stripe Connect. Wrote 500+ automated tests exposing the billing logic gaps, set up local Stripe webhook integration, and prepared a full data migration to Supabase.
500+ Automated tests written — ~20 billing bugs found
Retail AI · 2025
The problem
An interactive AI avatar deployed in a Swiss beauty store was silently draining API credits due to WebSocket connection issues. Customers were getting dropped mid-conversation.
What we built
Diagnosed and fixed the WebSocket lifecycle management, added full conversation logging, and rebuilt the frontend for reliable real-time performance. Ongoing remote support via AnyDesk.
Live In-store AI avatar — stable, logged, and supported
"One of the most skilled teams I've worked with. Fast, precise and proactive."
Retail Tech Director
Healthcare Tech · 2024
The problem
Medical teams needed a HIPAA-compliant way to transcribe multi-speaker audio files, with clean speaker identification and flexible export for downstream workflows.
What we built
Full-stack audio transcription platform built from scratch. Users upload files, Deepgram processes them with speaker diarisation, and outputs TSV, DOCX, or JSON. Includes Google OAuth, HIPAA-compliant mode, project management, and automated file cleanup. Deployed on Fly.io.
HIPAA Compliant — full-stack, built from scratch
"SimpleAI delivered on time and on budget, and communicated tangible solutions when they hit problems."
Healthcare CTO
Cloud Storage SaaS · 2024
The problem
A founder needed a secure cloud storage MVP with auth, file management, nested folders, and usage-based Stripe billing — shipped fast.
What we built
Full-stack MVP: authentication, file upload and viewing, nested folder structures, and Stripe usage-based billing. Built and shipped in one week.
7 days From brief to shipped MVP
"SimpleAI set up the entire system in a way that was easy for me to understand and manage."
Founder, Cloud Storage SaaS
Presentation SaaS · 2023
The problem
A media company needed a browser-based tool to create templated presentations at scale — drag-and-drop editing, variable placeholders, and bulk generation from a CSV upload.
What we built
SaaS prototype: slide editor with drag-and-drop text and images, CSV-driven variable population, and .pptx download. Prototype delivered in days.
Days From idea to working prototype
"Very professional and great at communicating project needs."
Media Director
B2B Directory · 2023
The problem
An existing React web app needed a CMS backbone to power a browsable manufacturer directory, replacing a hardcoded data approach that the team couldn't maintain.
What we built
Integrated Strapi CMS into the existing codebase — browsable directory with search, filtering, and user favourites. Clean handover with editorial workflows the team could manage themselves.
CMS Integrated — search, filter, and favourites
"Shows absolute competence in picking up your current tech stack with ease. Fast and detailed with great communication."

Fashion / AI · 2022
The problem
A fashion resale startup needed a demo tool to show investors how AI could let buyers virtually swap clothing on photos.
What we built
An AI-powered inpainting tool: users select a clothing region, enter a prompt, and the tool generates a composite image with the outfit replaced. Backend chains three model calls — segmentation, inpainting, and compositing — via Stable Diffusion.
3-stage AI pipeline: segment → inpaint → composite
