- Teamed up with the United States Space Force utilizing eXtreme Programming (XP) methodology to enhance two warfighter support applications developed using Kotlin, React and MySql and deployed to K8’s. This simplified ordering Space Support for US Joint Forces and Coalition Partners around the world. Outcomes were dropping response times from 5 days to as low as 7 minutes for one application and creation of a live feed of high interest space events instead of a bi-weekly feedback loop on the other application.- Modernized New York City Department of Education application using ASP.NET Core 6, Angular 14 and SQL Server. Employed cloud native vertical slice architecture, CQRS, Http resilience policies, reactive programming and data access repositories in architecture. Outcomes were increased app responsiveness by over 90% and leaving behind patterns and practices the department could use moving forward.

-Mentoring 3 junior developers with designing new components, code reviews and debugging by pair programming. This improved core libraries, reduced code redundancy, decoupled code and made modules easier to test.- Managed newly formed team of 4 to develop Feed mill information management system using Angular, ASP.NET Core and C#. Grew from underperforming Agile team to best performing team in 4 month span. Overwhelming improvement of team led to adoption of new Scrum artifacts including a dedicated scrum master positively impacting performance of every team.- Led Mobile development team in creating monolithic code base approach usable on any type of mobile device regardless of operating system using Ionic, Angular, iOS & Android. This cut development costs ~70%.- Supervised team of 4 engineers to implement two client / server applications for service technicians to score and record performance of contract growers, run reports and store signed contracts. This allowed establishment of newer more accurate Key - Performance Indicators by management allowing them to make crucial business decisions. It also increased operation efficiencies of organizations by more than 90%. Another positive outcome was it allowed over 100 tech advisors to simplify daily operations by cutting down time spent on administrative tasks by over 100%.- Led research and development effort to move backend Azure SQL hosted Single Database application service to multi-tenant SaaS. When adopted, new infrastructure will allow company to reach small-scale farmers as subscription costs will be lowered ~85%.- Developed IoT solutions to capture telemetry from devices on farms like weight scales and gauges, provide real-time alerts to customers and use AI to predict outcomes and advise where action needs to be taken using Azure Cloud Services, C#, Ionic and Angular. This saved farmers roughly 3 hours per day performing bird checks.
