Hypersistence

Chief Technology Officer

Nov 2016 – Present · 9 yrs 6 mos · Cluj, Romania · On-site

At Hypersistence, we dedicate ourselves to helping companies get the best out of their software systems through training, consulting, and offering high-quality products that optimize their development processes.
After analyzing the most common causes that lead to performance issues, I developed several training materials to share the knowledge that I have accumulated over my career of 20 years. Some of the most successful training options have been: High-Performance Java Persistence, High-Performance SQL, and High-Performance Spring Persistence.
To automate the process of finding performance bottlenecks in Java applications, I created Hypersistence Optimizer, which can detect mapping, configuration, and data access logic problems automatically during testing so that you can fix them long before they manifest in production and affect your business flow.
