Selected work / Open source / Expertise
I'm Manos, a senior software engineer based in Athens, Greece. I build full-stack products and tools for evaluating coding agents. My work spans Angular and React interfaces, Node.js backends but I am open in any challenging opportunities regarding latest technologies.

Can a coding task be graded fairly? An agent pipeline that screens SWE-bench-style tasks for unclear requirements and overly restrictive tests. It checks cited evidence against the source and compares verdicts with public human annotations. Includes reproducible evaluations, readable agent traces, and installable agent skills.

My latest upstream pull requests, newest first, with live status badges:
| Project | Contribution | Status |
|---|---|---|
| ngx-mask | Let the mask directive bind Angular signal-form fields typed as number or nullable, fixing a template type error that only string fields escaped. |  |
| Analog | Transpile decorated Angular files skipped by the compiler with TypeScript instead of OXC/esbuild in Vitest, fixing a coverage PARSE_ERROR on untested components. |  |
| Transloco | Render interpolated param values like UUIDs literally in the MessageFormat transpiler, instead of parsing their braces as ICU syntax and throwing. |  |
| ngx-bootstrap | Emit null instead of undefined when the datepicker input is cleared, fixing a crash with Angular signal forms. |  |
| Radix NG | Keep the Popper arrow visible when the popup shifts off-center, exposing data-uncentered for styling instead of silently hiding it. |  |
