About

Senior .NET and SQL Server Developer with over 20 years of experience building, maintaining, and modernizing business-critical systems across industrial, financial, healthcare, and cybersecurity domains.

What I Do

I work on the full stack of business-critical systems — from SQL Server stored procedures and .NET backend services to Windows Server infrastructure and industrial device integrations. My work spans legacy modernization, production troubleshooting, IT/OT systems, and AI-assisted engineering workflows. I focus on understanding business rules before changing code, working directly with operations teams and end users, and ensuring systems stay reliable under real-world conditions.

Industries

Industrial & Logistics

RFID tracking, PLC integration, SCADA-style telemetry, warehouse management, and manufacturing execution systems.

Healthcare Technology

Systems supporting clinical workflows, data privacy, and regulatory compliance in healthcare environments.

Banking & Financial

Backend services, transaction processing, reporting, and financial data systems with high reliability requirements.

Cybersecurity & Identity

Identity management, access control, data protection, risk assessment, and security monitoring systems.

Access Control & Physical Security

Biometric readers, RFID access cards, gated-community management, and visitor registration systems.

Energy

Monitoring, telemetry, and control systems for energy infrastructure.

How I Work

  • Business-first approach: Understand the business rules, user workflows, and operational constraints before touching production systems.
  • Direct collaboration: Work directly with users, operations teams, and stakeholders — not just through tickets and intermediaries.
  • Full-stack investigation: Trace issues across application code, database queries, server configuration, network connectivity, and connected devices.
  • AI-assisted, human-reviewed: Use AI tools to accelerate analysis and generate options, but keep human judgment and review over every production change.
  • Quiet reliability: Focus on systems that work correctly, perform predictably, and can be debugged efficiently when things go wrong.
