Full-stack & mobile engineer — 15+ years delivering for US, UK & Brazilian teams.
// about
I'm a Senior Software Engineer with 15+ years of experience across full-stack and mobile — Swift, Kotlin, Node, Vue, Python. I've shipped products with US, UK and Brazilian teams, from consumer apps in pre-launch to internal platforms for local businesses. Currently pursuing an MSc in Artificial Intelligence at the University of the Cumberlands.
I started writing software professionally in 2010 and have spent the years since moving between agency work, product startups, senior mobile roles, and running my own practice (FontTech) building tailored software end-to-end. I care about clean architecture, products that actually fit the people using them, and going deep into the technologies I work with. Right now I split my time between Chiku Inc, where I'm helping ship a consumer photo app, my own products, and an MSc in AI focused on applying LLMs and modern tooling to real problems.

// kind words
"Leandro has exceptional technical skills, and he always adds to the team that he is working with. He likes to go deep into the technologies he is using to get the most out of them. He is very proactive and always available to help the team. I certainly recommend Leandro as a professional, regardless of the project he is invited to participate in."
"Leandro is one of the most intelligent people I've worked with. You're not getting a developer only — you get someone who cares about the product, the client's needs, and the overall architecture. He takes each project as if it's his and cares about the outcome. He's excellent at iOS and web apps, backend solutions and databases, and he doesn't mind a challenge."
"Leandro has been so professional and always there to help his teammates. He writes clean, readable and properly documented code. Despite having little knowledge of the iOS framework, I was able to understand his code and the logic behind it. I believe he will be a great asset for any company."
"Leandro is extremely easy to work with — someone who would always be available to help out other team members. He is an extremely hardworking individual who would go an extra mile to ensure deadlines are met and the work delivered is top notch. He also has a good understanding of tech stacks other than iOS."
