PostgreSQL, Vector DBs & ETL Pipelines
Databases Services
I design and optimise database systems — PostgreSQL, MySQL, MongoDB — and implement vector databases (pgvector, Weaviate, Qdrant) for AI applications. I also build ETL pipelines and handle zero-downtime data migrations. Fast, reliable, and production-hardened.

FAQ
Databases Questions
Specific answers about databases services.
What is a vector database and when do I need one?+
A vector database stores mathematical representations (embeddings) of text, images or data. You need one when building AI applications like semantic search, RAG chatbots, or recommendation engines. Popular options include pgvector (built on PostgreSQL), Weaviate, Qdrant and Pinecone.
What is the difference between pgvector and Pinecone?+
pgvector is a PostgreSQL extension — free, self-hosted, and great for keeping all your data in one place. Pinecone is a managed cloud service with higher performance for very large scale. For most projects, pgvector is the better starting point.
How do you migrate a database without downtime?+
I use a dual-write strategy: new records write to both old and new databases simultaneously, then I backfill historical data, validate, and cut over DNS in one atomic switch. For most projects this achieves sub-second cutover with zero data loss.
How do I know if my PostgreSQL queries are slow?+
I use pg_stat_statements to identify slow queries, EXPLAIN ANALYZE to diagnose execution plans, and add appropriate indexes (B-tree, GIN, BRIN) based on your query patterns. A typical optimisation engagement cuts p99 query times by 60–90%.
Can you set up automated database backups?+
Yes. I configure pg_dump / mysqldump scheduled backups to S3 or equivalent storage, with retention policies, encryption at rest, and monthly restore tests to verify backup integrity.
