Services
My Skills, Applied Directly.
-
Web Engineering
High-performance Web sites and applications, plus bespoke WordPress/WooCommerce systems and automated fulfillment pipelines where e-commerce is the job.
-
Desktop Application Development
Full C#/WPF systems built solo, from MVVM architecture to production-ready management suites.
-
Compiler & DSL Engineering
Custom languages, AST parsers, and compilers - built to turn repetitive work into a single command.
-
Developer Tooling
CLIs, VS Code extensions, and libraries designed around real developer workflows, not just working code.
-
System Architecture
Systems designed to fit the problem at hand - scoped, documented, and built to be maintained by someone other than me.
-
Legacy Audits & Modernization
Existing codebases reviewed, migrated, and brought current - dependencies, configs, and patterns included.
Skills
Skills Mastered. Depth Proven.
Principles
Explicit by Design. Consistent by Practice.
How I Code
-
Explicit
No magic, no hidden behavior. Names and interfaces say exactly what they do.
-
Deliberate
Frameworks, libraries, or custom code - each is chosen on its own merits, never by default.
-
Grounded
Decisions backed by real usage data, not assumptions about what might scale.
-
Thorough
Existing tools get audited and migrated forward, not left to rot after launch.
How I Work
-
Adaptable
Stack, domain, or team - the approach adjusts, the standards don’t.
-
Disciplined
Consistent process and standards, whether or not anyone is checking.
-
Pragmatic
Manual work, frameworks, or AI - whatever gets the outcome right, used fully.
-
Curious
New tools and patterns get evaluated early, ahead of being necessary.
How I Deliver
-
Need-driven
Built to solve a real, present problem - never a speculative one.
-
Cohesive
Personal work builds toward one ecosystem; client work stays scoped to what each project needs.
-
Persistent
Shipped is not finished - maintenance and refinement continue long-term.
-
Resourceful
Limited resources sharpen a solution, they don’t stop it.
