Case Studies
From App Store launches to factory-floor handoffs — here's what happens when HarQuinn Tech plugs in.
Hardware & Manufacturing
From Silicon to Factory Floor
PropTech Hardware DFM Audit — Saving $2M in Manufacturing Risk
A PropTech client's smart lock hardware had critical design flaws that would have caused a 34% factory defect rate. Our DFM audit caught them pre-tooling and saved over $2M in projected rework costs.
Custom IoT PCB Design — Industrial Sensor Platform
Designed a 12-layer IoT sensor PCB for an industrial monitoring client — from schematic to certified production board with full EMI compliance and FCC pre-certification testing.
MedTech Device Compliance & Certification Pathway
Guided a medical device startup through FDA pre-submission, IEC 60601 electrical safety compliance, and CE marking — compressing an 18-month certification timeline to 9 months.
Mobile & Web Development
Apps That Ship & Scale
AI Food Saver — Full-Stack Mobile App Launch
End-to-end development of an AI-powered food management app — from concept and UI/UX design through native iOS and Android builds to live App Store publication.
B2B SaaS Operations Dashboard — Enterprise Web Platform
Built a full-featured operations management platform for a logistics company — real-time data, role-based access, and custom reporting — replacing 4 legacy tools with one unified system.
Cross-Platform Field Service App — React Native
Delivered a cross-platform field service management app in 14 weeks — offline-first architecture, GPS tracking, and real-time job dispatch for a 200-person service team.
Enterprise & Cloud
Infrastructure That Scales
Legacy-to-Cloud Migration — GCP & Firebase Architecture
Migrated a retail enterprise from on-premise servers to a fully serverless GCP + Firebase architecture — reducing infrastructure costs by 71% and achieving 99.98% uptime in the first quarter post-launch.
IoT Fleet Security Hardening — 500 Device Network
Conducted a full penetration test and security architecture review on a 500-device IoT fleet — discovered 14 critical vulnerabilities and delivered a remediation roadmap that closed all issues in 8 weeks.
End-to-End IoT Platform — Silicon to Cloud Dashboard
Designed and deployed a full IoT stack — custom sensor hardware, embedded firmware, edge computing layer, and a real-time GCP cloud dashboard — for a smart building management client.
What Clients Say
Straight From the Team
The people we've built with.
"HarQuinn Tech caught a critical design flaw in our smart lock PCB that would have cost us over two million dollars in factory rework. Their DFM audit paid for itself a hundred times over before we ever placed a production order."
"They took our app idea from napkin sketch to App Store in under six months. The UI is beautiful, the backend is rock solid, and they handled every part of the submission process. We didn't have to hire a single additional engineer."
"Our cloud migration with HarQuinn Tech cut our AWS bill by 71% while improving reliability. They know GCP and Firebase at a level I haven't seen from any other firm. Truly an extension of our own engineering team."
