Designed and developed the Petabytes grade horizontally scalable MSSQL-based storage, with schema on read approach. This allowed storing and reading a huge amount of data extracted from thousands of applications. MSSQL was a constraint, no other DBs were allowed.
The latest project was: 
A web backend software that integrates with an existing desktop clinical patient management system to extract, store and use data to provide additional services like reminders, patient forms, etc. In addition, exposes/sells API to a 3rd party to have custom solutions. 

Project Role: from Middle Software engineer to Application Architect

Improved development and support time, by providing comprehensive design and work decomposition to the stakeholders.
Provided predictable project executions, by leading estimations sessions and risks register and analysis. 
Led to the improvement of maintainability, by introducing coding standards and ingested a code review process
Shortened the time to market from 4-6 months to days by aligning the SDLC process with branching strategies, decreased services coupling, and removed cycle dependencies. 
Decreased services coupling that led to independent deployments, by introducing and implementing Event-Driven Architecture and messaging.
Implemented horizontally scalable Petabatypes grade storage solution by using Sharding and Catalog patterns with MSSQL.
Improved team skills, by having regular learning sessions, and dev meetings where discusses issues and ways that can be solved and preparing individual development plans.
Improved interoperability of the APIs by using the world knows healthcare information exchange standard -  FHIR 
Improved monitoring and reliability by adding Prometheus and Grafana to gather and process metrics to statistics/trends and fire alerts.
Improved the application/service acceptance and testing time from weeks to hours/minutes by introducing microservices auto-testing technics.
