I lead teams that turn vision into product.
I'm Lucas Possam, a tech lead with more than ten years across engineering, product and business. I've been an engineer, product manager and CTO. Today I lead technical teams that ship with quality and impact.
I've sat on every side of the table.
I started as an engineer and kept taking on more of the product: I was Co-CTO at an accelerator, founded a software house, was CTO of an agribusiness startup, and Product Manager of a SaaS. Today I'm a tech lead at Galileu.
That path gives me a view beyond the code. I set the architecture, prioritise together with the business, build and mentor teams, and create the processes that make delivery predictable and sustainable.

Joining as Co-CTO, I had the honor of being mentored by a great professional. Together we built a complete innovation management suite, plus a full e-learning platform for every project selected through the rigorous evaluation algorithm of Latin America's largest startup accelerator.

MedRoom
Sr. Software Engineer
I had the pleasure of diving into the world of 3D and virtual reality. An amazing experience with a fantastic team of artists and developers — but a short one, since we were acquired by one of Brazil's largest education groups, which pushed me into the world of entrepreneurship.
- 2021–2023
Familyst Co.
Founder
I got to sell, serve, plan, manage and deliver more than 10 projects, with quality and fair pricing, plus an excellent customer experience. It took me to a more strategic level and gave me skills that proved indispensable for the next steps of my career.

Mavielo
Consultant > CTO > CEO
The project that made me shut down the software house and dive headfirst into this experience. After 3 months as a consultant, I was invited to join Mavielo's partners and take the CTO seat. That's when we started turning the founders' ideas, sketched on paper, into screens. After the launch, I was promoted to CEO and took the lead of an engaged, dedicated and talented team, with whom we achieved fast user-base growth and enviable product and marketing quality.
- 2024–2025
Whaticket
Sr. Product Manager
At Whaticket I officially stepped into the Product Manager role. Facing the challenge of returning to the corporate world, a 2-year backlog and a high bug count, we built an organization that drastically reduced technical debt and bug incidence, shipped visual changes that brought modernity and accessibility, and delivered features essential to the product's growth. We also created the processes needed for a smooth and consistent operation, fostering a deep understanding of users and solid go-to-market strategies, aligned with an impactful product vision and a data-driven strategy.
- 2025–Present
Galileu
Sr. Software Engineer > Tech Lead
Day to day, I build and evolve the product, helping the team grow sustainably while keeping a high technical bar. I take part in the decisions that shape the project's architecture and direction, mentor colleagues and encourage good coding practices. I use Laravel, React.js and Remix to ship new features focused on quality, performance and user experience.
Shall we build the next team?
I'm open to tech lead and engineering leadership roles, and to talking about teams and products that need to grow with quality. Drop me a line.
