I am a Data Architect with a MCSA: SQL Server 2012/2014 certification. I have over 15 years of experience writing SQL/T-SQL queries and managing the Charleston County School District's internal relational data warehouse which is stored on a SQL Server. I develop C# applications in Visual Studio to accommodate user needs and as a way to provide accurate information to schools in regards to state accountability measures. I create and maintain SQL Server Integration Services (SSIS) packages that import the PowerSchool SIS Oracle data into a local SQL Server to be used for ad-hoc reports, and for the data integration into multiple vendor software systems, and automated 10+ scripts to streamline these data uploads into vendor software on a nightly basis. I also create and maintain student-level dashboards in SQL Server Reporting Services, which are used during teacher conferences. I am very efficient and dependable, and I am interested in helping other companies with their SQL and and web development needs.

I am a seasoned Postgres database architect specializing in architecture for data-driven processes such as ERP's, CRM's, Fintech, etc. Chances are you are not using your database nearly to the capacity it can serve you and I can fix that. I am a systems design engineer first and foremost. Writing queries (with supreme excellence) is an art form, but still only secondary to the most important element: architecture which is where I excel the most. Beyond that, I'd say my "traditional" Postgres skills (listed below) are above average as well. Fair warning: I consider databases to be first-class citizens. I have developed a very successful workflow for producing good results. It begins with patiently asking questions to understand all of the contextual needs and then going about solving them in an iterative process with lots of two-way communication along the way. I utilize a loose framework and building workflow that makes it inherently easy to change and adapt as needed. This is important because good design is never achieved in the first iteration, so making architecture amenable means it can always get better. While I can obviously help with smaller projects, its the bigger challenges such as overhauls and ground-up projects that suit me best. I excel in complex cases and situations involving higher maths, algorithms and fuzzy logic. Traditional Skills: - ETL, Migrations, Imports - Advanced Functions/Procedures - Advanced/Complicated Query writing and optimization - Custom triggers, aggregates, types, etc. - User/role/security management - Indexing - Config tuning
