Relational & NoSQL Database Engineering

Enterprise Database Architecture & Performance Tuning

We design, optimize, and scale relational (PostgreSQL, MySQL), NoSQL (MongoDB, Redis, DynamoDB), and vector databases, engineered for sub-millisecond query execution, zero-downtime migrations, and enterprise HA replication.

Database Engineering Practice

From PostgreSQL EXPLAIN ANALYZE query tuning to Patroni HA clusters, pgvector AI search, and AES-256 security.

PostgreSQL & MySQL

Relational Schema Design & SQL Tuning

We design normalized 3NF relational schemas and perform deep EXPLAIN ANALYZE query tuning on PostgreSQL and MySQL databases, eliminating slow queries and locks under heavy multi-client concurrency.

3NF database schema modeling & foreign key constraints
B-Tree, Hash, GIN, & GiST index optimization
EXPLAIN ANALYZE query execution plan refactoring
PgBouncer connection pooling & max connection scaling

Database Delivery SLA Standards

  • Sub-1ms Redis cache & 10x SQL query acceleration
  • Patroni streaming HA replication & 99.999% SLA uptime
  • AES-256 storage encryption & TLS 1.3 security

Database Execution Lifecycle

How We Engineer Databases

A disciplined, test-driven engineering lifecycle from ERD data modeling to zero-downtime deployment.

01

Data Modeling & Entity Relationships

We analyze query patterns, access frequency, and design normalized 3NF or document data models with ERD diagrams.

02

Indexing & Execution Plan Strategy

Formulate index strategies (B-Tree, GIN, HNSW) and simulate high-concurrency read/write query patterns.

03

HA Cluster & Connection Pool Setup

Provision cloud RDS / Supabase databases with PgBouncer connection pooling and multi-AZ standby failover.

04

k6 Concurrency & Query Stress Testing

Rigorous benchmark testing simulating peak enterprise workloads to verify sub-10ms response times under load.

05

Zero-Downtime Data Migration

Execute live CDC data sync and blue/green schema cutovers without interrupting active user transactions.

06

Slow-Query Telemetry & 24/7 SLA Support

24/7 monitoring of query latency, lock contention, memory usage, and automated daily WAL backups under agreed SLAs.

Client Advisory & FAQs

Database Engineering FAQ

Answers to common questions regarding PostgreSQL vs MongoDB, zero-downtime migrations, and EXPLAIN query tuning.

PostgreSQL (SQL) is the gold standard for transactional applications requiring strict ACID compliance, complex relational joins, foreign key integrity, and vector search (via pgvector). MongoDB (NoSQL) is recommended for rapidly evolving, unstructured document models (e.g. flexible JSON catalogs) or horizontally sharded write-heavy workloads.
