Database Expertise
Choose the Right Database for Your Workload
Each database engine has strengths. Selecting the right one for your data model, query patterns, and scale requirements is the first decision that shapes everything downstream.
PostgreSQL Database Services
The most advanced open-source relational database. ACID compliance, JSONB for semi-structured data, PostGIS for geospatial, pgvector for AI embeddings, and extensions for virtually any use case.
MongoDB Development Services
Flexible document store for content platforms, catalogs, and rapidly evolving schemas. Aggregation pipelines, change streams, and Atlas for managed deployments.
MySQL Database Services
The most widely deployed open-source database. Proven reliability for web applications, CMS platforms, and SaaS products with straightforward replication and broad hosting support.
Redis Caching and Data Store
In-memory data store for caching, session management, rate limiting, pub/sub messaging, and real-time leaderboards. Sub-millisecond reads at any scale.
Elasticsearch and OpenSearch Services
Full-text search, log analytics, and observability at scale. Elasticsearch and its AWS-managed fork OpenSearch share the same core capabilities: inverted indexes, aggregations, and the ELK/OpenSearch stack for operational intelligence.
Amazon DynamoDB Services
Fully managed NoSQL on AWS. Single-digit millisecond performance at any scale with auto-scaling, global tables, and tight Lambda integration.
Neo4j Graph Database Services
Graph database for connected data. Fraud detection, knowledge graphs, recommendation engines, and social network analysis using Cypher query language and native graph storage.
Vector Database Development
Similarity search over AI embeddings using pgvector (PostgreSQL extension), Pinecone, Weaviate, or Qdrant. Powers RAG pipelines, semantic search, and recommendation engines.
Engineering Services
Database Development Services
From schema design and database consulting through production optimization and administration, database engineering services that cover the full lifecycle of your data layer.
Normalized relational schemas, document structures, or key-value patterns designed for your query workload. Indexing strategies planned before the first row is written.
Query analysis, index optimization, connection pooling, memory tuning, and vacuum configuration. Measurable latency improvements on existing databases.
Schema conversion, data transfer, stored procedure rewriting, and application-layer changes. Oracle, SQL Server, and MySQL to PostgreSQL. Zero-downtime cutovers.
Streaming replication, read replicas, automated failover with Patroni or cloud-native tools, and documented RPO/RTO targets tested under failure scenarios.
Provisioning, parameter tuning, backup policies, and monitoring on AWS RDS, Aurora, Azure SQL, Cloud SQL, MongoDB Atlas, and ElastiCache.
Polyglot persistence design for systems that need multiple database engines. When to use relational, when to add a cache, and how to keep them in sync.
Selection Guide
Choosing the Right Database
Choosing the wrong database is expensive to fix later. This guide covers the most common decision points.
PostgreSQL vs MySQL
Choose PostgreSQL when the project needs complex queries, JSONB, full-text search, or advanced extensions (PostGIS, pgvector). Choose MySQL when the priority is simple setup, broad hosting support, or compatibility with WordPress/PHP ecosystems.
PostgreSQL vs MongoDB
Choose PostgreSQL for structured data with relationships, transactions, and complex reporting. Choose MongoDB when the schema changes frequently, documents are deeply nested, or the team needs flexible indexing without upfront schema design.
MongoDB vs DynamoDB
Choose MongoDB when the application needs rich queries, aggregation pipelines, and multi-cloud portability. Choose DynamoDB when the workload is on AWS, needs single-digit millisecond latency at any scale, and access patterns are known upfront.
When to Use Redis
Add Redis when the application needs sub-millisecond reads for session data, API response caching, rate limiting, or real-time leaderboards. Redis complements a primary database, not replaces it. Use it alongside PostgreSQL or MongoDB for hot data.
SQL vs NoSQL
Choose SQL (PostgreSQL, MySQL) for applications with relationships, joins, transactions, and regulatory requirements. Choose NoSQL (MongoDB, DynamoDB, Redis) for high-write throughput, flexible schemas, or workloads with specific access patterns like key-value lookups or document retrieval.
When to Use a Graph Database
Choose Neo4j or a graph database when the core value is in relationships between entities: fraud detection, recommendation engines, knowledge graphs, or social networks. Relational joins become expensive at 3+ hops. Graph databases handle deep traversals natively.
