Work with me
I help organizations design, rescue, and scale mission-critical enterprise systems — translating complex business requirements into resilient architecture.
With 18+ years of experience across telecommunications, energy, and national public systems (including 11 years in engineering leadership), here is where I provide the highest leverage:
System Analysis & Architecture Blueprints
Turning ambiguous business rules into battle-tested specifications, workflow state machines, and data schemas your engineering team can build with confidence.
Rating, Billing & Order Fulfillment Systems
Deep domain expertise in complex enterprise engines: order fulfillment workflows, product pricing calculators, rating, billing, and payment reconciliation.
Legacy System Rescue & Modernization
Auditing undocumented monolithic applications, mapping architectural traps, identifying data integrity leaks, and building risk-managed modernization roadmaps.
Database & Oracle Engineering
High-performance schema modeling, PL/SQL engineering, query tuning, and large-scale data processing/ETL for high-throughput environments.
Security-Aware System Design
Designing application access controls, approval hierarchies, and audit trails backed by certified security analyst standards (EC-Council ECSA).
How it works:
- Tell me about your system challenge → Hire me on Upwork
- We evaluate the core problem and scope the smallest high-impact milestone.
- I deliver blueprints or code, you review — we iterate.
