Web applications at SYSOPS

SYSOPS works with client companies, notably in the construction sector, on their IT and software. As an apprentice, I contribute to web applications built for concrete business use.

A business application is only valuable if it fits the way people actually work. The challenge isn't just adding features: it's evolving the tool without breaking what works, while taking the feedback of the people who use it into account.

• –Business users, not technical ones: the interface has to stay obvious.
• –Applications in daily use: every change must be tested before it ships.
• –Company data: confidentiality and rigour about what is handled.

• –Building features with Next.js and React.
• –Back-end and database work with PHP, SQL and Supabase.
• –Testing changes before they are made available.
• –Incorporating user feedback into improvements.
• –Translating stated needs into concrete technical changes.

• –Understand the usage before touching the code: who uses this screen, and to do what.
• –State the expected change in a way that can be checked.
• –Implement in small, individually tested increments.
• –Go back to users and adjust.

Front end: Next.js and React. Data: PHP, SQL and Supabase, depending on the application. The technical work always stays tied to a need expressed by a user or a client.

This work teaches me to judge a feature by its real use: a successful change is one that saves someone time or prevents a mistake in their daily work.

• –The best specification is still watching how the tool is really used.
• –Testing before shipping protects users' trust, not just the code.
• –A small, well-aimed change is often worth more than a rewrite.
