// CORE DOMAINS

Explicit architectural separation

01 / TRANSACTIONAL & MISSION-CRITICAL

Database Administration (RDBMS)

Ensuring high-availability, clustering, and kernel-level performance tuning for high-throughput OLTP workloads.

Oracle (RAC / MAA / Data Guard) PostgreSQL (Patroni / PgBouncer) MS SQL Server (AlwaysOn)

Zero Data Loss architectures with guaranteed RPO=0
Deep SQL tuning, execution plan stability & latch optimization
Cross-platform migrations and enterprise Disaster Recovery (DR)
Production-grade 24/7 reliability and operational resilience

02 / PETABYTE-SCALE ANALYTICS

On-Premise Data Lakehouses

High-performance analytical platforms deployed on dedicated internal infrastructure without public cloud lock-in.

Spark-Based Engines Trino Query Engine Dremio Semantic Engine StarRocks (Vectorized OLAP) Apache Iceberg / Parquet

Unified storage and compute layer using Open Table Formats
Sub-second vectorized OLAP and distributed federated queries
ACID transactions, time-travel, and schema evolution on Iceberg
Enterprise governance, fine-grained access, and compliance

// CONTEXTUAL LAYER

Data Modeling & Contextual Data Modeling (CxDM)

Rigorous data modeling is the foundation of dependable analytics and AI. We apply proven modeling methodologies (3NF, Kimball Star Schema, Data Vault 2.0) alongside Contextual Data Modeling (CxDM) designed for LLM execution.

Instead of exposing raw tables to AI agents, CxDM establishes a deterministic Contextual Layer through strict domain contracts and AST Guardrails—delivering accurate, secure Text-to-SQL and Enterprise RAG.
