Linux application development and infrastructure architecture
Linux is the foundation of modern enterprise infrastructure. I build applications, design deployment architectures, and integrate Linux-based platforms with existing business systems — including IBM i, Windows, and cloud environments.
What I Build on Linux
- Server-side application development (Java, Python, Go, Node.js)
- API development and microservices
- Containerization with Docker and Kubernetes
- CI/CD pipelines and build automation
- Infrastructure architecture and deployment design
- Security hardening and compliance-aware configuration
- Cross-platform integration — IBM i, Windows, and cloud
- Banking and payment integrations (NACHA, ACH, Positive Pay, Stripe, Authorize.net)
Cross-Platform Integration
Linux rarely exists in isolation. Most organizations run Linux alongside IBM i, Windows, or cloud services — and the systems need to exchange data reliably. I build the integrations that connect these platforms through JDBC, APIs, EDI, file exchange, and real-time data pipelines.
For IBM i environments, Linux is often where modern web services, reporting tools, and customer-facing applications run — connecting to IBM i business logic through JDBC and web services. I work across both platforms, which means the integration is designed by someone who understands both sides.
Free Linux & Ops Tools
Developers and SREs running services on Linux can use these free browser-based tools for the everyday utilities that come up in development and operations — scheduled jobs, config conversions, pattern testing, and ID or hash generation.
- Cron Expression Builder — build and explain crontab expressions for scheduled jobs
- YAML ↔ JSON Converter — bridge Kubernetes manifests, Ansible playbooks, and JSON configs
- Regex Tester & Builder — test regular expressions with live matches
- JSON ↔ CSV — bridge API payloads and spreadsheet-style data
- Connection String Builder — assemble JDBC and ODBC strings for cross-platform connectivity
- Hash Generator — MD5, SHA-1, SHA-256, and SHA-512 for strings and files
- UUID Generator — generate v1, v4, and v7 UUIDs
- Base64 Encode/Decode — encode and decode text and binary data
