Hire the Best PostgreSQL Developers & DBA
in the United States

I am an experienced database administrator for MySQL and MariaDB. I am an American citizen and have an active security clearance. I have been working with MySQL since release 4.1. I have extensive experience in database design and implementation, writing SQL, tuning databases, and creating operational environments for database hosts. I write complex SQL (including stored procedures and functions), assist development teams with writing their SQL, debug performance problems, and diagnose issues with database performance in production. I also write Perl programs to perform a variety of database related tasks. On the operational side I install and maintain database servers, create backup and recovery jobs, define and implement replication strategies for load and recovery management, and implement business reporting platforms. My experience with database applications ranges from high-transaction large volume systems to small web applications having a single database. My work is based on *nix based systems. With the planned obsolesce of MySQL 5.7 I can help you with upgrading to MySQL 8.

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

I'm a data professional with a Bachelor degree in computer science, with 8+ years of experience in the field and have been working in small and big data enterprise solutions. During my professional path, I worked in several roles like DBA, Data Architect, Data Engineer, Data Governance and Business Analytics team support. My experience comes from hybrid environment projects with cloud providers like AWS, Google and Azure. I can mention some of the most challenging projects in my professional career where I am proud to produce an impact in the organizations. The actual Chilean Public Education payment service, which managed almost 3,2% of the country's PIB can calculate and assign the Education money for every public school in the country using variable metrics managed by user, my expertise in Databases and integrations was key in the actual calculation workflow process. I was able to developed a service to recollect Chilean Public transportation data from real-time social network and combine with the buses GPS data for analytics, so the Managers could make decisions for quality service improve from the service user perspective taking actions rapidly. I was part of the team that create and deploy the first Africa online tax service in Kenya, where I took in charge of the modeling and support of the Oracle operational database, the service was a game changing, lowing in big manner, the cost of the tax recollection in Kenya. And lastly I design and had feed the Datawarehouse of a Chilean financial big company with the data required that allowed to the company made the correct decision about what king of products needed to focus. All of it, with a mix of database services like Azure SQL Server, GCP Bigquery, MongoDB and PostgreSQL. With the work on mixed environments and budgets, I can mix open-source technologies like low-code solutions like Pentaho, Airflow, db and Processmaker, with proprietary services in the cloud like lambda functions, Athena, Google Compose, Azure ADF or Glue, plus coding skills like SQL, python, Java and Regular Expressions (for text data query). I also have experience with Data visualization tools like Google Data Studio, Clickview, PowerBI, SSRS, Webfocus and Pentaho Reporting Services, knowledge of it because of the need to support BI Teams in some projects. Its seems likely that I missed a more specialized technical profile, but it was the result of the need to work with disparate clients and industries, however I feel very confident with the whole enterprise data journey path, from data modeling and processing to data visualization and it allows me to see the big picture in data solutions implementations.
