Database Architect Hybrid DBA / Developer Performance & Reliability ERP / Migration & Integration

I design, implement, and stabilize mission-critical database environments. My sweet spot is hybrid execution: architectural clarity, operational depth, and hands-on delivery across performance engineering, integrations, and ERP migration programs.

            Enterprise Oracle Depth
            Oracle 7 → 23ai, APEX 1.x → 24.x, on-prem + modernized stacks.
          
            Operational Credibility
            Architecture + admin + recovery (RMAN), security posture, production reliability.
          
            Business-Impact Delivery
            ERP integrations, automation, and performance recovery where vendors stalled.

Hybrid DBA / Developer

Hands-on build-and-operate execution: schema design, SQL & PL/SQL engineering, APEX apps, and ORDS services. I aim for systems that are both elegant and supportable.

SQL / PL/SQL APEX ORDS REST / SOAP Automation

Performance & Reliability Engineering

Root-cause analysis and durable remediation: StatsPack/AWR/ASH, execution plans, indexing strategy, resource contention, and operational hardening (backup/recovery, monitoring, change safety).

StatsPack / AWR / ASH Execution Plans Indexing & Stats RMAN Linux Ops

ERP / Data Migration

Integration-first migrations with clear control points: data conversion pipelines, validation, cutover planning, and supportable interfaces across enterprise partners.

Broader Data Systems

Oracle is my core focus, but I’m comfortable owning SQL Server environments and integrating heterogeneous systems in production settings.

SQL Server T‑SQL SSIS Sybase Interop

Selected Engagements

Representative work themes from enterprise environments (healthcare supply chain, utilities, and regulated operations). These are written to communicate outcomes without oversharing proprietary details.

ERP Modernization Architecture Integrations

ERP Transition Architecture & Integration Stabilization

Led database architecture strategy supporting modernization toward Oracle Fusion ERP.
Built and maintained automated data integrations across enterprise partners (e.g., supply chain ecosystems).
Improved operational accuracy with automation-first workflows and clear validation checkpoints.

Performance Recovery StatsPack/AWR/ASH SQL Engineering

Production Performance Diagnostics & Durable Remediation

Diagnosed chronic performance issues using StatsPack/AWR/ASH and execution plan analysis.
Delivered prioritized remediation: SQL refactoring, indexing strategy, statistics hygiene, and safe rollout plan.
Stabilized business-critical processes and reduced recurring escalations.

Reliability RMAN Operations

Backup/Recovery Architecture & Operational Hardening

Designed and tested backup/restore workflows and operational runbooks for supportable recovery.
Hardened Linux-based operations: change safety, monitoring, and incident response practices.
Focused on resilience: reduce surprises, shorten recovery time, protect data integrity.

Full‑Stack Oracle APEX ORDS

Rapid Application Delivery on the Oracle RAD Stack

Built APEX applications supporting analytics, operational workflows, and reporting enablement.
Exposed controlled APIs via ORDS to integrate external processes cleanly and securely.
Delivered cost-effective systems with pragmatic UX and production-grade supportability.

Infrastructure Backbone (This Site Runs on It)

This isn’t a static brochure: it’s fronted by hardened HTTPS and reverse proxying into ORDS and APEX, backed by a live Oracle RDBMS. The goal is to quietly demonstrate real operational engineering.

Hardened HTTPS Proper certificate chain + renewal automation, production-style config discipline.

Reverse Proxy Isolation Clean front-door routing with loopback isolation to app services.

ORDS + APEX Live endpoints and demos powered by Oracle’s RAD stack.
