About this Gig

Is your database slowing you down or holding your product back?


A poorly structured database is a ticking time bomb: slow queries, duplicate

data, broken relationships, and painful scaling. I fix that before it starts.


I specialize in relational database architecture, normalization, and

performance optimization built for systems that need to last and scale.


With 10+ years of experience, including government-scale enterprise systems,

I design databases that are:


  • Fully normalized (1NF 3NF / BCNF)
  • Optimized for query performance
  • Scalable and future-proof
  • Structured for reporting & analytics
  • Production-ready from day one


WHAT YOU GET


  • Complete SQL schema (MySQL / PostgreSQL / SQL Server)
  • ER-structured relational design
  • Proper indexing strategy (composite, covering, partial)
  • Many-to-many relationship modeling with junction tables
  • Constraints & data integrity enforcement (FK, CHECK, UNIQUE)
  • Sample optimized queries tailored to your use case
