Case studies

Software engineering case studies, measured in uptime, latency and load.

Selected work in healthcare, security, HRTech, retail and AI: the problem, what we changed and the measurable result.

Cross-domain · Messaging & notifications

A notification service that sends over 10,000 messages a day, with delays and retries.

On healthcare, HR and security products we built a service for mass email, SMS and push notifications: templates, personalization, scheduled delivery and recipient segmentation. It runs on queues with idempotent sending, retries and delayed delivery, tracks results through the Mailgun API and webhooks, and respects recipient consent and unsubscribes. The client got a service that sends a large volume of notifications on a delivery schedule, resends failed ones and reports analytics.
