Has your project gotten to the point when big data sets and/or time-consuming calculations have begun to affect performance? Or are you struggling to optimize your queries and need to cache some information to avoid continually hitting your database? Then caching could be your solution.
For this article, I will demonstrate how to utilize Amazon ElastiCache for Redis to speed up areas of your application. The example application we will build uses Spring Boot 2.x and is available on Github.
A notification system often starts with a simple requirement: send an email, text message, or push notification when something happens in an application. For a small system, calling an external provider directly may be enough. As traffic grows, however, notification delivery becomes a distributed systems problem. A production notification platform needs to handle traffic spikes, provider failures, duplicate events, retries, delivery tracking, and multiple notification channels without slowing down the application that generated the notification.
This article explores how a scalable notification system can be designed using Spring Boot and Kafka, with a focus on asynchronous processing, fault tolerance, idempotency, retries, and horizontal scaling.
A founder-built application created with AI coding tools ran into common AI-assisted development challenges, including missing source code and performance issues. Keyhole Software reconstructed the system, optimized Python processing, and enabled a successful launch. A client without a formal software background spent close to a year building a stock alerting app, mostly using AI-assisted coding tools and a lot of …
Software development trends in 2026 is being reshaped by forces that extend well beyond incremental tooling improvements. AI-assisted development, cloud-native infrastructure, and zero-trust security are no longer experimental capabilities.
