Hire the Best Database Modeling Experts
in Georgia

I build and optimize databases that hold up under real production load and turn raw data into reporting that actually answers business questions. Over 6+ years I've worked as a database developer and engineer across gambling, healthcare, and banking. Most notably, I spent 6 years with Flutter (the group behind FanDuel, Paddy Power, and Betfair), where I designed and built Oracle/PostgreSQL database objects from scratch - packages, procedures, functions, triggers - for revenue-critical promotional systems, achieving 4x performance gains through indexing, partitioning, and query rewrites, and later built ETL pipelines (Apache NiFi, ClickHouse, BigQuery) feeding BI reporting. I've also architected a centralized MySQL schema for clinical-trial data at a healthcare client, improving data extraction speed by 80%, and earlier built IFRS-compliant regulatory reporting for a bank and executive Tableau dashboards for another. I hold a Master's degree in Information Technologies and I'm comfortable across PostgreSQL, MS SQL Server, Oracle, MySQL, and ClickHouse. What I can help with: • Complex queries, stored procedures, functions, triggers, and scheduled jobs • Database schema design and performance optimization (indexing, partitioning, query rewrites) • ETL pipelines and data warehouse builds (Apache NiFi, BigQuery, ClickHouse) • Translating business requirements into technical specs I'm newer to Upwork specifically, but not new to this work if you need a database built correctly the first time, or an existing one cleaned up and made fast, let's talk about what you're working on.

I'm professional developer and programmer with 15-years experience in database projecting using database management systems: MS Access, MySQL, MS SQL Server, Oracle. I'm expert in MS Office VBA and VBScript/Autoit (also have some experience in Python and C#). During long time I worked as a software developer, an analyst, a technical writer and a project manager from the customer side. I went through hell and high water working with contractors. Very often contractor's work is full trash and I hate such approach to work. I do my work very well with maximal efforts to satisfy my clients with my experience and offer only best solutions. I understand your needs, I know how it works and how it has to work. I love every my client because they give me that sense of freedom... freedom from contractors trash work and crazy bosses ideas which I can't affect to. I offer for my clients the following solutions: 1) MS Access - as desktop database solution for 1-5 users and as data handling tool for the data volume less than 2 Gb; 2) MS Access + MySQL - as client-server database solution for more than 5 users and databases with large volume of data (it gives optimal price/perfomance ratio for client); 3) VBScript and AutoIt scripts - for loading and handling/converting information with scheduler. I like my work very much... it's something like art for me.
