DECODED CAPABILITY
Comfortable with Linux for shell work, processes, permissions, services, logs and terminal-driven automation.
This means faster onboarding on real servers, less operational friction and more autonomy during debugging.
Fast CLI navigation, shell scripts and terminal-first workflows
Comfortable reading processes, services, ports, permissions and file systems without relying on a GUI
Confident with remote environments and direct troubleshooting on Linux hosts
DECODED CAPABILITY
Comfortable working with domains, DNS records, propagation, subdomains, mail routing and connected configurations.
For a company this means connecting apps, websites, email and environments quickly, without getting stuck on infrastructure details.
Handling A, CNAME, MX and TXT records while connecting external services
Spotting common propagation issues and configuration mismatches
Keeping branding, email and deployment aligned from an operational perspective
DECODED CAPABILITY
I pay attention to certificates, HTTPS, redirect hygiene, browser trust warnings and the consistency of the public layer.
That reduces customer-facing issues and improves perceived product reliability from the very first visit.
Checking certificates and public-facing configurations for consistency
Paying attention to redirects and browser-exposed surfaces
Avoiding small mistakes that become very expensive once they hit production
DECODED CAPABILITY
I care not only about writing code, but also about shipping it through a clean, readable and repeatable release flow.
A company gets less release chaos, clearer handoffs and someone who can contribute to delivery, not just implementation.
Attention to the transition between local, staging and public environments
An organized approach to rollout and final verification
Ownership across the full path, not only the feature itself
DECODED CAPABILITY
I like reading signals, errors and odd behavior to reconstruct where the flow is actually breaking.
That is extremely useful when real issues need to be understood quickly instead of being approached by blind trial and error.
Pattern-oriented reading instead of focusing only on isolated errors
Connecting UX, backend and infrastructure signals during debugging
A practical attitude toward finding bottlenecks and anomalies
DECODED CAPABILITY
Familiar with the operational details that keep contact flows, forms, delivery and domain credibility working smoothly.
These are not glamorous topics, but they directly affect leads, support flows and online reputation.
Attention to email flows connected to websites and public forms
Practical understanding of the relationship between domains, records and deliverability
Care for the details users only notice when something breaks
simo@dev:~$ ls -la ./projects
Local LLM runner that reads and reasons on your message while you type, so the wait after Enter drops from 12.2 s to 3.2 s on Qwen3-4B. Built on llama.cpp with GUI, TUI and CLI.
This site. A static Astro build served by one Cloudflare Worker, with a hardened contact API (Turnstile, validation, rate limiting, Resend), a staging Worker, no framework JavaScript, a real shell on every page and a text profile for curl.
Website for Aryaplus, an Italian telecom and ICT provider for businesses. Seven solution areas, separate journeys for companies and resellers, the company story, careers and partner sign-up, built with Astro and React islands.
High-school project from 2023. A football apparel shop in plain PHP with an MVC structure, sign-up and login, cookie sessions, SQL injection prevention, an admin sales dashboard and Docker.
