Database Cost Optimization & Performance per Dollar ($/QPS)
Migrating from expensive proprietary databases (Oracle, MSSQL, Snowflake, DynamoDB) to modern alternatives (PostgreSQL, ClickHouse, DuckDB, Valkey, TiDB).
Decomposing a Core Monolith into High-Velocity Microservices
The Enterprise Challenge
A high-volume transactional platform was constrained by a 12-year-old monolithic database backend. Deployment cycles required 4 hours of maintenance downtime, and minor bugs repeatedly brought down payment processing.
The i26 Engineering Solution
i26 deployed a dedicated Senior Engineering Pod to implement the strangler-fig pattern. We isolated payment routing, authentication, and order ledgers into independent Go and Node.js microservices running on private Google Kubernetes Engine (GKE) clusters connected via Kafka event streams.
Measurable Operational Outcomes
- 99.995% transaction availability with zero maintenance downtime
- Deploy frequency accelerated from bi-monthly to multiple daily deploys
- Transaction throughput increased 4.5x with sub-50ms p99 latency
Consolidating 8 Fragmented Data Silos into a Modern Cloud Lakehouse
The Enterprise Challenge
Diagnostic, patient, and billing records were scattered across multiple disjointed SQL Server, Postgres, and proprietary legacy databases. Generating quarterly compliance and clinical reporting required weeks of manual CSV stitching.
The i26 Engineering Solution
Engineered an automated ELT pipeline using Apache Flink and dbt into an encrypted BigQuery lakehouse inside the client private VPC. Integrated role-based access control (RBAC) with column-level masking to maintain strict HIPAA compliance.
Measurable Operational Outcomes
- Automated real-time synchronization across all 8 operational systems
- Executive clinical dashboard load times dropped from 22 minutes to 850 milliseconds
- 62% reduction in cloud storage and legacy database licensing costs
Air-Gapped Private Enterprise AI & Knowledge Retrieval (RAG)
The Enterprise Challenge
Enterprise leadership sought to implement LLM-assisted contract drafting and risk analysis, but corporate legal and infosec strictly prohibited exposing proprietary contracts to public third-party APIs (OpenAI/Anthropic).
The i26 Engineering Solution
Deployed self-hosted, quantized open-weights models (Llama-3 70B and Mistral) inside the enterprise private cloud VPC with dedicated GPU acceleration. Built a vector knowledge retrieval engine using pgvector with strict tenant-level isolation and zero public internet connectivity.
Measurable Operational Outcomes
- Zero byte data egress outside the corporate firewall
- 80% reduction in contract review and compliance analysis turnaround time
- Complete verifiable audit trails for every AI-generated citation
Offline-First Mobile Platform for Multi-Depot Fleet Operations
The Enterprise Challenge
Over 400 warehouse inspectors and drivers operated in remote connectivity dead-zones. Manual paper logging led to widespread inventory discrepancies and delayed dispatch schedules.
The i26 Engineering Solution
Crafted an offline-first React Native mobile application for iOS and Android with SQLite local caching and bidirectional delta synchronization. Built an intelligent conflict resolution engine that pushes updates immediately upon detecting network availability.
Measurable Operational Outcomes
- Over 40 regional distribution hubs digitized with real-time telematics
- Inventory reconciliation errors reduced to near-zero
- Average daily driver dispatch processing accelerated by 45 minutes
Zero-Trust Cloud Infrastructure & 45-Day SOC2 Fast-Track
The Enterprise Challenge
A Series B enterprise SaaS provider was losing high-value Fortune 500 sales deals due to a lack of formal SOC2 Type II certification and unversioned cloud infrastructure.
The i26 Engineering Solution
Codified 100% of cloud resources into Terraform modules with automated least-privilege IAM policies, AWS KMS customer-managed key encryption, automated CI/CD security scanning, and tamper-proof CloudTrail audit logs.
Measurable Operational Outcomes
- Completed official third-party SOC2 Type II audit in 45 days with zero non-conformities
- Cloud infrastructure drift eliminated with automated PR verification
- Accelerated enterprise procurement approval cycles by 3x
