You will get Fix Slow MySQL, MongoDB & AWS RDS (Queries, Replication, Performance)
Rising Talent
Project details
Optimize, stabilize, and scale production database systems with a focus on performance, reliability, and long-term operational efficiency.
This project delivers advanced database troubleshooting and optimization across MySQL, MariaDB, Percona Server, MongoDB, and AWS-managed services including RDS, DynamoDB, and Redshift. Designed for business-critical environments, the scope focuses on identifying performance bottlenecks, resolving slow queries, improving indexing strategies, and ensuring efficient resource utilization under real-world workloads.
Work includes deep analysis of query execution plans, indexing and schema optimization, connection and memory tuning, replication and clustering improvements (including Percona XtraDB Cluster and Galera), and addressing high-load or scaling constraints. Infrastructure-level considerations may also be included, such as I/O performance, storage configuration, caching layers, and cloud-based optimization within AWS environments.
All changes are approached with production safety in mind, incorporating validation, rollback awareness, and minimal disruption to live systems.

+$150 - $250About Blair
AWS OpenStack Hybrid Cloud Engineer | DBA | E-Commerce
Las Vegas, United States - 11:55 am local time
Trusted in **live production environments**, I implement safe, reversible changes that improve performance, stability, and scalability without risking downtime or data integrity.
AWS Certified Solutions Architect – Associate (Renewal Scheduled) | AWS Certified Cloud Practitioner | RHCE 6 | B.S. Business (111/120) | MBA AI Product Management
(I prefer fixed-scope project quotes for development, migrations, and architecture/decoupling by timeline vs hourly, unless for targeted troubleshooting or DBA support.)
---
With 13+ years of experience across AWS, OpenStack, Rackspace, Liquid Web, and UpCloud, I design and optimize **data-driven systems spanning SQL, NoSQL, distributed databases, caching layers, and cloud-native architectures**.
I support both **SMB and enterprise environments**, aligning solutions to system scale, complexity, and business requirements.

## Database & High-Availability Systems
* MySQL, MariaDB, Percona Server
* Percona XtraDB Cluster (PXC), Galera clustering
* PostgreSQL, SQLite
* MongoDB and NoSQL systems
* AWS RDS, DynamoDB, Redshift, Athena
Supporting infrastructure:
* ProxySQL, HAProxy (routing, load balancing, failover)
* Replication, clustering, and distributed database systems
Specializing in:
* Performance tuning, indexing, and query optimization
* Root cause analysis (slow queries, locking, contention)
* High-availability architecture and failover strategies
* Backup, recovery, and data integrity validation
* Production incident debugging and stabilization
* Scaling databases under real-world load and concurrency
---
## Architecture & System Design (Headless / Serverless / Distributed)
* Headless architectures (decoupled frontend + API-driven backend)
* Serverless systems (AWS Lambda, event-driven workflows)
* API-first systems (REST APIs, webhooks, integrations)
* Microservices architectures and distributed data flows
I design systems where **data consistency, latency, and coordination across services** are critical under production load.
---
## Platforms & Environments
* **E-Commerce** — WordPress, WooCommerce, Magento (cart systems, session handling, checkout reliability)
* **Cloud Infrastructure** — AWS and hybrid systems (scaling, cost optimization, reliability)
* **High-Traffic Applications** — concurrency, session persistence, and state management
* **Game & Real-Time Systems** — event-driven backends, progression systems, real-time data
* **Search & Analytics** — Elasticsearch / OpenSearch
---
## Caching, CDN & Performance Layers
* Redis, Memcached, AWS ElastiCache
* Multi-layer caching (object cache, full-page cache)
* Cache invalidation and consistency across distributed systems
* CDN & edge delivery (CloudFront)
* Session storage and cart persistence across environments
Experienced in coordinating **application, database, cache, and CDN layers** to maintain performance and consistency under load.
---
## Database Migrations & Decoupled Systems
* Zero/low-downtime migrations
* Data consistency across APIs, services, and frontend layers
* Coordinated schema, cache, and service-layer transitions
* Migration strategies for e-commerce, cloud-native, and real-time systems
---
## Core Outcomes I Deliver
* Resolve **critical production issues** quickly and safely
* Improve **database and application performance**
* Stabilize **unreliable or failing systems**
* Reduce **cloud and infrastructure costs**
* Scale **revenue-generating and high-traffic platforms**
Focused on measurable outcomes: **faster performance, improved uptime, lower costs, and better conversion performance**.
