PostgreSQL Experts Who Tame Your Data Layer.
PostgreSQL specialists who design schemas that stay fast at scale and migrations that don't take your app down. Our engineers handle everything from initial data modeling and indexing strategy to replication, partitioning, and disaster recovery — embedded in your team from day one. We serve data-intensive product teams across the United States, Germany, Netherlands, and the UK, with 4–6 hours of daily CET overlap and GDPR-compliant database management.
Use Cases
What we build with PostgreSQL.
Schema Design & Data Modeling
Normalized schemas with proper constraints, domain types, and referential integrity for transactional workloads. Denormalized JSONB structures when flexibility is needed. We've designed database architectures for multi-tenant SaaS platforms in Berlin, healthcare record systems in Amsterdam, and financial transaction ledgers for companies on Wall Street.
Query Performance Optimization
EXPLAIN ANALYZE–driven optimization: rewriting slow queries, adding targeted indexes (B-tree, GIN, GiST, BRIN), and restructuring joins. Materialized views for expensive aggregations and partial indexes for filtered lookups. Reduced p95 query latency by 10x for analytics dashboards in Munich, search APIs in London, and reporting tools across the US market.
Zero-Downtime Migrations
Schema migrations that run against live production databases without locking tables or dropping connections. Concurrent index creation, column backfills with batched updates, and expand-and-contract patterns for breaking changes. Executed migrations on 500GB+ databases for marketplace platforms in Stockholm and enterprise SaaS in New York with zero user impact.
Multi-Tenant Database Architecture
Row-level security policies, schema-per-tenant isolation, or database-per-tenant patterns depending on compliance and performance requirements. Connection pooling with PgBouncer, tenant-aware backup strategies, and cross-tenant analytics. Built for B2B platforms serving clients across the EU that require strict data isolation per GDPR mandates.
Full-Text Search & Geospatial Queries
PostgreSQL's tsvector search with custom dictionaries, ranking functions, and trigram similarity for fuzzy matching — replacing ElasticSearch for many use cases. PostGIS for geospatial queries: radius searches, polygon containment, and route optimization. Powered search for job boards in Paris, property platforms in Dublin, and delivery services in Hamburg.
Replication & High Availability
Streaming replication with automatic failover using Patroni or pg_auto_failover. Read replicas for analytics workloads, cross-region replication for disaster recovery, and logical replication for zero-downtime major version upgrades. Architected HA setups for payment processors in Zurich, SaaS platforms in Copenhagen, and trading systems in Chicago.
Expertise
How we work with PostgreSQL.
Advanced Indexing Strategies
We select index types based on query patterns: B-tree for equality and range, GIN for JSONB and arrays, GiST for geometric and full-text, BRIN for time-series data. Partial indexes reduce bloat, expression indexes handle computed lookups, and covering indexes eliminate heap fetches for hot queries. Every index justified by EXPLAIN output.
Row-Level Security & Access Control
PostgreSQL RLS policies that enforce tenant isolation, role-based data access, and field-level permissions at the database layer — not just the application layer. Combined with pgcrypto for column-level encryption of sensitive fields. Essential for EU clients who need GDPR-compliant data access controls baked into the storage engine.
Connection Pooling & Resource Management
PgBouncer or Supavisor for connection pooling in serverless and high-concurrency environments. We tune shared_buffers, work_mem, effective_cache_size, and maintenance_work_mem based on workload profiles. pg_stat_statements for identifying slow queries and pg_stat_user_tables for monitoring table bloat and autovacuum effectiveness.
Backup, Recovery & PITR
WAL-based continuous archiving with pg_basebackup or pgBackRest for point-in-time recovery. Automated backup verification with restore testing. Cross-region backup replication for disaster recovery. EU-resident backups stored in eu-central-1 or eu-west-1 for clients with data residency requirements under GDPR.
PostgreSQL Extensions Ecosystem
We leverage pg_partman for declarative partitioning, TimescaleDB for time-series workloads, pgvector for embedding similarity search, and pg_cron for scheduled database maintenance. PostGIS for geospatial data, hstore and JSONB for semi-structured storage, and uuid-ossp for distributed ID generation across microservices.
Why us
Why TBI for PostgreSQL.
Fast Onboarding, Immediate Impact
Our PostgreSQL engineers review your schema, query patterns, and slow query logs before day one. They arrive with optimization recommendations and a migration plan — not questions about how your tables relate. First impactful change typically ships within 2–3 days.
AI-Augmented Database Engineering
Our engineers use AI tools to generate migration scripts, analyze EXPLAIN plans, and scaffold complex SQL queries. AI handles the repetitive SQL patterns — JOIN variations, CTE structures, window functions — while our engineers focus on indexing strategy, data modeling decisions, and performance trade-offs.
US & EU Timezone Overlap
Working from IST (UTC+5:30), we overlap 4–6 hours with CET and 3–4 hours with US Eastern. Database incidents are time-sensitive — our overlap means migration coordination, failover testing, and performance investigations happen in real-time with your team, not via overnight Slack messages.
GDPR-Compliant Data Management
Row-level security for tenant isolation, column-level encryption for PII, EU-region database hosting, and automated data retention policies. We implement right-to-deletion as cascading database operations with audit trails. DPAs signed, backup residency configured, and access logging enabled by default for all EU client databases.
FAQ
Common questions.
How much does it cost to hire a dedicated PostgreSQL engineer offshore?
Dedicated PostgreSQL engineers start at $5,000/month. Senior DBAs and database architects with expertise in replication, partitioning, and performance tuning range from $6,500–$9,500/month. In the US, a senior database engineer costs $150,000–$200,000/year; in the EU, €90,000–€130,000/year. Our engineers deliver the same depth of expertise — schema reviews, query optimization, HA architecture — at 60–70% lower cost.
How fast can a PostgreSQL engineer start optimizing our database?
2–3 days to first actionable improvement. Before onboarding, they analyze your pg_stat_statements output, review your schema, and identify the top slow queries. Day one typically includes an index recommendation or query rewrite that shows immediate measurable impact. No weeks of "getting familiar with the data model."
How do you handle zero-downtime schema migrations on large tables?
We use expand-and-contract patterns: add the new column, backfill in batches with row-level locks (not table locks), update application code to write to both columns, then drop the old one. Indexes are created with CREATE INDEX CONCURRENTLY. For enum changes and constraint additions, we use NOT VALID followed by VALIDATE CONSTRAINT to avoid full table scans under lock.
How do you ensure GDPR compliance at the PostgreSQL level?
Row-level security policies enforce tenant data isolation at the database engine level — not just the app layer. PII columns use pgcrypto encryption. Audit tables log every access to sensitive data. Automated retention jobs purge expired records. Databases are hosted in EU regions with encrypted backups stored in the same region. We sign DPAs covering all database operations.
What timezone overlap do your database engineers provide?
Our engineers work from IST (UTC+5:30), overlapping 4–6 hours with CET and 3–4 hours with US Eastern. Database work often requires coordinated maintenance windows — our overlap ensures migration deployments, failover tests, and emergency performance fixes happen while your team is available to verify. For scheduled maintenance, we accommodate off-peak windows in your primary timezone.
