Software Development Case Studies

Six production projects: healthcare platforms, AI pipelines, luxury CRMs, and marketplace tools. Each one built for a real client who had a real problem that off-the-shelf software couldn't solve. Every metric below came from their live system, not a controlled demo.

Featured Case Study

Replacing fragmented tools with a HIPAA-compliant care coordination platform that speaks HCHB natively

A US-based home health startup needed more than a chat tool. They needed a platform that understood episodes, IDG meetings, and ADT events. We built CareCoordinations with bidirectional HCHB integration from day one.

MyQRGuide: Post-Sale Customer Platform

Amazon and eBay sellers face a structural problem: they fulfil the order, but the marketplace owns the customer. No email address. No phone number. No way to follow up, upsell, or resolve a problem before it becomes a 1-star review. Every sale is effectively a one-time transaction, even for repeat buyers.

Automated Product Image Pipeline
Luxury Commerce

Automated Product Image Pipeline

The client buys luxury watches from auctions around the world. Each acquisition needs to be photographed, background-removed, quality-checked, and uploaded to their product system before it can be listed for sale. With 1,500+ images per week, the manual process had become the bottleneck.

Proofit: Blockchain IP Certification

Intellectual property theft is invisible until it is too late. Traditional IP protection (patents, trademarks, copyright registration) is expensive, slow, and often overkill for everyday creative work. A freelance designer does not need a patent, they need a fast, affordable way to prove their design existed on a specific date before anyone else claimed it.

Luxury Watch & Jewellery CRM
Luxury Retail

Luxury Watch & Jewellery CRM

Running a luxury watch and jewellery business involves more complexity than typical retail. New stock alongside pre-owned and mint-condition pieces, repair workflows, staff commission tracking, and dual online/in-store channels, generic CRMs like Salesforce or HubSpot were built for B2B sales pipelines, not for a retail operation where the "deal" is a physical object with a serial number, a service history, and a chain of custody.

RAG Pipeline for AI Knowledge Assistant
AI Engineering

RAG Pipeline for AI Knowledge Assistant

Most AI chatbots share the same fatal flaw: they hallucinate. The client needed an AI assistant embedded across thousands of seller mini-sites, each with different content. The AI needed to answer accurately from that specific seller's content, not generic knowledge. Off-the-shelf AI integrations had no source grounding, no confidence thresholds, and no way to know when the AI was guessing.

Production-only

Every case study here ran in a live system for a paying client. We do not include prototypes, internal tools, or demos.

Verifiable outcomes

Metrics are from client reporting, platform analytics, or before/after comparisons, not marketing estimates.

Domain-first

Healthcare, luxury, and e-commerce are not interchangeable. Each project reflects years of vertical knowledge, not a generic build.
