There were two big applications with complex business processes and workflow. During this project, significant performance optimization--including database performance--was implemented.

In addition to development, I provided 24/7 product support and resolved urgent customer issues on production. I also managed and delegated customer requests during the working day. I communicated with the customer, performed requirement analysis and high level project estimations, and took part in the resolution of production-related issues, including hot fixes and complex database patches.
