Expert PostgreSQL/MySQL Administration

Are you looking for an experienced database (PostgreSQL and MySQL) engineer/administrator who can help you optimise your database queries, tune your database servers, and scale your database cluster for high availability and throughput? Look no further.

I am the founder of Gotedo Platform (the largest technology platform for churches and Christians (https://about.gotedo.com). I am a senior backend engineer with 9+ years of software engineering and database management experience, and I consider myself an expert in MySQL and PostgreSQL. I have worked with databases with hundreds of tables and millions of records.

A poorly designed schema or inefficient query can bring your entire system to a halt. I have deep, long-term experience in relational database management, especially PostgreSQL and MySQL.

✅ What This Service Includes:

1. Expert Database Design: I will architect your database schema from scratch or migrate your existing schema, crafting tables for maximum referential integrity and performance. I utilize advanced entities like tables, views/materialized views, partitioned tables, and Common Table Expressions (CTEs).
2. Advanced Query Optimization: I often prefer raw SQL queries to ORM methods for maximum query control and performance. I have extensive experience crafting highly optimized SQL queries for complex analytics. At Gotedo, I wrote queries for over 30 analytical charts covering more than 100 datasets.
3. Performance Tuning: I can tune your PostgreSQL server settings for maximum performance based on your specific hardware and workload. 
4. High Availability & Disaster Recovery: I understand how to set up PostgreSQL and MySQL for high availability and replication. I can implement robust Point-in-Time Recovery (PITR) strategies by managing Write-Ahead Logging (WAL) and setting up twice-daily database dumps and WAL archiving.
5. Reactive Database Programming: I understand how to use triggers for reactive database operations, allowing the database itself to enforce complex business logic. 

✅  My Proven Expertise:

1. I have deep understanding of database migration strategies, indexing, and performance optimization. I have written thousands of idempotent migration and seeding scripts in my career.
2. My experience extends to managing database pooling (PgBouncer) and setting up robust firewall rules to protect database servers.
3. I have also built resilient and performant queue systems using PostgreSQL itself, demonstrating my ability to push the database beyond simple data storage.

✅ Technology Stack:

1. Databases: PostgreSQL, MySQL, SQLite. 
2. Tooling: PgBouncer. 
3. Languages: SQL, JavaScript, TypeScript, Golang.

Don't let your database be your bottleneck. Hire an expert who understands database architecture from the schema design up to high-availability server administration. I will ensure your database is a fast, reliable, and secure foundation for your application.
