In just one day, I built a mobile app prototype that demonstrates how Precisely APIs can enable real-time decision-making in the field—without deep prior experience using Precisely capabilities or the developer platform.
For context, I joined Precisely about 3 months ago as a Product Specialist. I have a background in data, engineering, and product, but I was completely new to Precisely’s offerings.
When the R&D team announced a Hackathon focused on the Data Integrity Suite APIs, I jumped at the chance to participate. I’m still ramping up, and this felt like the perfect opportunity to dive deeper, learn more about the APIs, and explore use cases that could deliver real value. I was curious: How far could I get with just the APIs and a single day to build? The answer surprised me—and it really highlights the flexibility of the Data Integrity Suite and how quickly it can deliver ROI.
The challenge was to build creative applications powered by the Data Integrity Suite APIs. I knew I could come up with something interesting and, in the weeks leading up to the event, I explored several ideas before landing on one that really stood out. What started as a learning exercise quickly became a proof point for how Telcos—and many other industries—can improve business outcomes and accelerate operations and analysis with trusted data and location intelligence.
What did I set out to build?
Telcos handle massive amounts of address data from various sources. As such, layering their own network data and business logic onto these geographic datasets to determine if an address is serviceable is a critical capability. Many customers are already centralizing these workflows in the Data Integrity Suite to create a single source of truth for their data.
For the hackathon, I asked myself: How can Precisely APIs amplify the value of that investment in the Suite?
My goal was to build a creative prototype—a model for what a customer might develop using Precisely’s Location Intelligence and Data Integrity Suite APIs.
The result was DoorWise, a mobile app designed to help field teams act on the most accurate, verified, and up-to-date data by identifying serviceable addresses. By unlocking real-time insights into serviceability, the app enables smarter sales strategies, driving efficiency and revenue.
How is it used?
Imagine you’re a door-to-door sales agent for a regional Telco provider. You’re starting your day and want to prioritize the streets with the highest concentration of homes that are both verified high-quality addresses and confirmed as serviceable based on the latest network data.
When you open the app, it centers on your current location and displays a map. You can adjust the search radius to focus on the area around you. The app then shows nearby streets, along with the number of verified, serviceable residential addresses on each one.
See a street with a lot of potential? Tap it to view all the addresses plotted on the map—and just like that, you know exactly where to start knocking.
How it works
With just a few API calls, DoorWise taps into trusted data, applies custom serviceability logic, and delivers the relevant information directly to field agents.
The app first calls Precisely’s Data Graph API, a single access point that streamlines access to connected data, to retrieve well-formed addresses within a defined search area. Using the Data Graph API’s dynamic data retrieval, I could request exactly the data I needed—clean addresses, geocoded coordinates, property type, and the unique PreciselyID—based on a simple polygon representing the area.
After filtering out non-residential properties, the app sends the address data to the Data Quality Pipeline Real-Time Service in my Data Integrity Suite workspace. This triggers a custom pipeline that applies serviceability logic using the provider’s network data, which is already cataloged in the Suite. A custom coding step annotates each address with its serviceability status.
By matching on PreciselyID, a unique, persistent identifier appended to addresses, the app combines the pipeline results with the original address data, filtering down to verified, serviceable residential addresses. The app then displays streets ranked by address count, with drill-down views showing individual addresses on a map.
All in a day’s work! Imagine a field agent seeing a map of streets ranked by ROI potential—powered by real-time data integrity.
I added a lightweight backend for request validation and API coordination to model production scenarios where business logic and authentication should stay out of client code. But the heavy lifting? That’s all handled by Precisely APIs.
As this was a one-day hack, I reached for a tech stack I knew well and had the most confidence in, knowing I could get a working prototype within 24 hours. Swift, SwiftUI, and Apple MapKit for the mobile app; Python and FastAPI for the backend. And of course, Copilot helped speed things up!

Why this matters
Building a door-to-door sales tool was a fun hackathon concept, but the bigger story is the potential it represents. A mobile app tapping into the power of the Data Integrity Suite opens the door to countless possibilities, from last-mile delivery to dynamic field operations. There’s no shortage of similar, Suite-powered applications that our customers could easily build and leverage to solve their biggest challenges and drive real-world value.
The serviceability pipeline and the way data was delivered to end users made this example especially compelling. It showcases how the Suite enables powerful data integrity tools to be put directly into the hands of non-data users across an organization. Within seconds, a field agent can access the latest source of truth for address and network availability data, running the same pipeline the data team uses in the Suite.
This prototype is just the beginning of what’s possible with these building blocks. It’s an exciting time to be at Precisely!
What I learned
Many organizations aim to “democratize” their data. I see tremendous value in using the Data Integrity Suite to establish guardrails and a single source of truth. From there, that trusted data can be made accessible across the organization, for both data professionals and field teams. Precisely APIs make that possible. The Suite can act as an organization’s single source of truth, while the APIs allow you to deliver that trusted data to anyone who needs it, in real time. The ability to deploy Data Quality Pipelines as real-time services opens up powerful possibilities.
This hackathon also gave me a new appreciation for unique IDs for location data. The PreciselyID was the glue that let me seamlessly connect multiple steps in the workflow and leverage Precisely services without losing address identity.
Overall, this was a fun challenge, and I’m proud of what I built in just 24 hours – with only a few months of familiarity with Precisely capabilities! It showed me what’s possible when trusted data meets creativity: turning data integrity into actionable intelligence across an organization. And this is just the beginning—Precisely APIs unlock countless opportunities to bring data integrity into everyday decisions. I’m excited to keep exploring these possibilities with customers!
