Verizon – Digital Sales & Upgrade Platform

Verizon's device upgrade and sales platform serves as one of the primary revenue channels for one of the largest wireless carriers in the United States. With over 8 million users hitting the platform monthly, performance, reliability, and conversion rate are not abstract metrics — they translate directly to revenue and customer retention.

Sapot Systems embedded a team of four engineers across a 16-month engagement to build, enhance, and sustain the customer-facing flows that handled device upgrades, new account creation, device selection, protection plan enrollment, and end-to-end purchase completion. The team also drove a performance optimization effort that addressed the underlying causes of slow page load times across the highest-traffic flows.

By the end of the engagement, page load times had been reduced by 60%, upgrade conversion had improved by 18%, and the platform continued to support 8M+ monthly users at improved reliability. The sustainment work ensured that improvements made were maintained as the platform evolved.

Why this matters for federal work: Federal citizen-facing applications — benefits portals, agency service platforms, .gov digital experiences — face the same engineering challenges as consumer platforms: reliability at scale, accessibility, and clear user flows under compliance constraints. This engagement demonstrates Sapot Systems' ability to deliver and sustain high-traffic applications where downtime and poor performance have direct consequences.
