Over the past years I have been gathering knowledge of all things data. Throughout my career I have successfully merged the concerns of data processing with those of software development, delivering datasets and tools with immense added value for my employers. As of late I have increasingly adopted the philosophy of DevOps, not only managing data transformation pipelines, but also their life-cycle and that of their supporting infrastructure, most notably by the use of Terraform in combination with AWS. I am hoping to capitalize on my accumulated expertise in a way that would not be possible on a long term job, delivering great value to individuals and companies that are willing to invest in order to reap excellent results. I am looking for projects that require a wide range of expertise and a capacity to think outside the box, projects with hard and challenging projects. I am also a fan of automation so projects that aim at a software solution for repetitive tasks (either for increased efficiency or scale) are also welcome. I hope my profile fits your requirements and I'm looking forward to hearing from interesting clients.

Hello, I am Ismael, a dedicated engineer MSc graduate from the Instituto Superior Técnico in Lisbon, always keen on learning more. Whilst I am Portuguese, I was raised in the French school system and as such I grew accustomed to a multicultural and international environment that allowed me to learn and speak 4 languages fluently. My professional and academic experience along with my internships developed both my ability to learn autonomously and to work as a part of a team, while also enhancing my critical thinking. About two years ago, I rediscovered a passion for software engineering that has allowed me to reinvent myself and I am looking for an opportunity to put my skills to use in order to grow professionally and to broaden my horizon.
