Build
01New Databases work from requirement to production: query and index tuning that turns seconds into milliseconds; Schema design and migrations for new features; Redis caching and Elasticsearch search added to an existing application.
Data and AI · 6 technologies
Databases — the part that is slow when everything is slow.
Most performance problems are database problems: missing indexes, N+1 queries, tables designed in a hurry. I design schemas, tune queries, add caching with Redis, set up search with Elasticsearch, and migrate data between engines when the current one is the wrong fit.

01 — What I do with Databases
build, fix, upgrade, audit
Fix and maintain
02The usual problems in existing Databases systems: pages that take ten seconds, backups that have never been restored, and a database growing without a plan.
Upgrade and migrate
03MySQL 5.x to 8, MongoDB major versions, moving reporting to a replica, adding Redis and search without downtime.
Audit and advise
04A code, security, performance and SEO audit of your Databases system, with a written plan you can act on with or without me.
02 — Technologies
what each one is for
MySQL
The default for Laravel; tuned, indexed and backed up.
PostgreSQL
For complex queries, JSON data and analytics.
MongoDB
Document storage where the shape of data varies.
Redis
Caching, queues, sessions and rate limiting.
Elasticsearch
Full-text and faceted search at scale.
SQLite
Embedded and small deployments, tests and local tools.

that actually gets ordered.
Three shapes most Databases engagements take. Yours may be a fourth; describe it and I will tell you honestly whether it fits.

04 — Questions
about Databases work
Can you speed up our database without a rewrite?
Nearly always. Indexes, query fixes and caching solve most cases. One rebuild went from 3,982 queries per page to 52, with the same database.
Do you do backups?
Yes, and restore drills. A backup that has never been restored is a hope, not a backup.
How is Databases work priced?
A fixed price for a defined scope, or hourly from $10 depending on the stack, always with a written estimate before any work starts.
How do we start?
Send a short description of what exists and what you need. You get a reply within one working day with questions, then a scope or an estimate.
