Diogo Lemos

Before moving into software engineering, I spent years running businesses in operations-heavy environments. Managing people, logistics, suppliers, schedules, and cash flow taught me how to make decisions under pressure and stay accountable for outcomes.

During the pandemic, I made a deliberate career change into technology. I studied through 42 Lisbon and the Bytes4Future bootcamp, where I moved from fundamentals to building full-stack applications with JavaScript, React, Node.js, and MongoDB in a fast, hands-on environment.

At LinkThings, I worked on authentication flows, database design, complex migrations, and internationalisation across multiple platforms. That experience gave me a strong foundation in product development, backend structure, and cross-functional delivery.

At PwC Portugal and Luxembourg, I focused on application performance, API-driven processes, and operational reliability. My work included improving serializers and views, reducing payload size, accelerating response times, and implementing monitoring for critical business flows.

Today, I work across the stack with tools such as Django, Nuxt, Vue, GraphQL, PostgreSQL, Docker, and observability platforms. I am especially motivated by projects that combine clear business value with sound engineering, whether that means improving a platform, building a multilingual product, or integrating hardware into a usable system.

What distinguishes me is not only the ability to write code, but also the perspective of someone who has managed teams, owned businesses, and changed careers with intent. I build with technical discipline, commercial awareness, and a strong bias toward practical results.
