PublicService — How ClockHash Built a Scalable Education Platform in Just Two Months

The Vision

Across Ireland, schools often face an unexpected challenge — finding qualified substitute teachers at short notice. Administrators spend hours coordinating calls, managing lists, and hoping someone is available. Teachers, on the other hand, miss opportunities because there’s no easy way to see where they’re needed. PublicService set out to change that.

Their goal was simple: create a digital bridge between schools and substitute professionals — a reliable, easy-to-use platform that keeps classrooms running without interruption. PublicService needed a trusted development partner who could turn their vision into a real, working product — fast. That’s when they turned to ClockHash, an Ireland-based technology company known for building production-ready MVPs that scale.

The Challenge

When the founders of PublicService approached ClockHash, they had a clear idea of what they wanted to build but needed the right team to bring it to life.

• - End-to-end development — from concept to launch.
• - Speed without compromise — the platform had to be live in two months.
• - Reliability — downtime was not an option for schools.
• - Scalability — so the app could grow across regions as adoption increased.

The education sector demands trust, performance, and security. One glitch could affect dozens of classrooms — so every decision mattered. ClockHash’s role wasn’t just to write code; it was to engineer confidence into every part of the product.

The Solution

ClockHash began with a deep discovery phase, mapping out the user journeys for both schools and teachers. What should happen when a principal needs a substitute teacher immediately? How can a qualified educator express availability or contact a school quickly?

With those questions answered, the team designed and built the MVP using an agile, modular approach — combining smart architecture, clean design, and continuous feedback.

• - Schools could post teaching requirements instantly.
• - Verified teachers could browse and contact schools directly.
• - Smart notifications reduced manual coordination.
• - Secure, scalable infrastructure supported growing use.

Within two months, PublicService had a fully operational app — not just an MVP, but a working platform ready for real-world adoption.

The Impact

Once launched, adoption happened quickly. Schools and teachers across Ireland began using PublicService almost immediately.

• - Faster connections: Schools filled substitute needs within hours instead of days.
• - Greater visibility: Teachers could see open opportunities and reach out directly.
• - Operational efficiency: Administrators reduced coordination time dramatically.

ClockHash continued the partnership with hosting, maintenance, performance monitoring, and iterative improvements — ensuring reliability and growth without technical friction.

Live and Growing

Today, PublicService continues to make an impact across Ireland’s education sector. The app is live and available for download on:

Each download represents another connection between schools and teachers — another day where learning doesn’t stop.

The Takeaway

PublicService’s success is a clear example of what happens when vision meets execution. In just two months, ClockHash helped a concept evolve into a real product — one that now supports schools, teachers, and administrators across Ireland.

For startups and founders, it’s a reminder that with the right partner, you can validate your idea, launch quickly, and start delivering value to users — all within weeks.
