About

An engineer by training.
Sharing knowledge throughout.

I’m Sara Ounissi. A Polytech Grenoble graduate and developer since 2017, I’ve built enterprise applications, taken on Tech Lead responsibilities and shipped products solo. Helping other women in tech has been part of that story since I founded TheTrendyCoder in 2021.

Engineering foundations, then real-world work.

I studied at Polytech Grenoble from 2012 to 2017, specialising in computer networks and multimedia communication. My final year took me to Montana State University in the US, studying computer science in an English-speaking academic environment.

I started my career at VISEO in October 2017, working on projects for HP, Hager and HomeSend: a chatbot, hybrid mobile applications and banking transaction interfaces. In 2019, a VIE placement with Sublime took me to New York, combining front-end development with daily communication with publishing partners.

Complex applications. Real responsibility.

At Norsys, I worked for Solocal on an ecosystem of around 150 Store Locator applications. Development, APIs, automation and support took the work well beyond implementing screens. In May 2022, I became a Tech Lead, handling technical coordination, priorities and client demonstrations.

From 2023 to 2025, I contributed to several internal RTE applications. On CONF, I was the sole dedicated front-end developer, from mock-ups to Angular upgrades. On Hypervision, I led a supervision application’s front-end redesign in close collaboration with design. I also worked on modernisation and accessibility across other interfaces.

In 2026, an Entoria assignment involved taking over insurance applications, building features with Angular and NgRx, resolving issues and contributing to Java / Spring back-end work. These experiences inform my architecture choices and my attention to what happens after delivery.

Giving women in tech a voice since 2021.

I created TheTrendyCoder in 2021. I published more than 50 articles covering development, tutorials, technical problems and lessons from experience, alongside interviews with women in tech.

Those conversations helped me build a small community and show careers people could identify with. The project lost momentum over time, but what it gave me still matters: a desire to make technology accessible and make room for other voices.

La Développeuse continues that work. I want to bring together my experience, products and teaching. Free resources are a starting point; what comes next will be shaped by the needs of the people using them.

My own products extend that work.

NgDigest, OrOGramme and Mensualio let me own an idea end to end: user need, data, design, development, testing and launch. I explore ways to make scattered information easier to understand and use.

AI helps me work across these areas. I remain responsible for architecture, decisions and validation. My engineering experience helps me question suggestions, understand trade-offs and check results.

Giving my work the space it deserves.

I tend to downplay my work. Yet my career includes an engineering degree, time abroad, complex projects and responsibilities I’ve taken on. I want to learn to describe it with the same care I bring to the work itself.

Seeing another woman’s career can help you imagine your own. That is what I want to keep doing here: show the work, explain the decisions and offer tools to move forward.

Details matter

Clear navigation, a useful error state, an accessible flow: these details are part of quality.

Show, then prove

Explain a decision, show the interface and say what still needs work. That is how I want to present my work.

Make people autonomous

Share the reasoning, examples and tools people need to understand and do things themselves.

The current stack

  • Angular
  • Zoneless SSR
  • TypeScript
  • FastAPI
  • NestJS
  • Design Systems
  • IA-assisted delivery

AI speeds up my work. Understanding, deciding and checking remain my responsibility.
