My experience include work with vary of clients, starting from eCommerce websites to air flights systems. With my involvement in analysis of their applications' performance, they increased their throughput in 3-4 times. I worked closely with both development and QA teams and especially solution architects.
It's important to me to build long term relationships with clients, so I'm primarily looking for long term projects.
With my help your application performance will satisfy all your needs and your clients' experience.
I look forward to hearing from you!
