HOW I CAN HELP YOU

I am an experienced software developer that cares deeply about user success and, therefore, your business success. I have been helping businesses of diverse industries and sizes for more than ten years.


Your customers and your profit are my top priority, so I deliver easy to use, intuitive, performant software, always focusing on the features that bring more value to your users and thus to you.

You can count on me to be an asset to your business and a problem solver. I have always been a curious person, not satisfied until I discover how things work and how to improve them. I do that by breaking problems into smaller issues until I get a good picture of the entire situation. And then, I tackle them one by one to solve them in an efficient and user-friendly way. I build simple, clean, and practical solutions that have longevity and are easy to maintain.

You can rely on my self-management skills. I have been working remotely full-time for over five years. I am autonomous, communicative, and proactive in reaching out and interacting with the team, yet capable of profoundly focusing on my work and delivering within deadlines.

Lucas was always able to figure out a solution within our business requirements, making him a highly valuable team member. His kind manner makes him a joy to work with!
Sean LawrenceFull stack Engineer at Make School
I have nothing but amazing things to say about Lucas. From advice on how to make a function simpler to read, to helping debug extremely complex bugs that I would have never found on my own, I've always been able to count on Lucas to help. He's not just a great engineer, but a fun, engaging person that shows a lot of empathy when he speaks to you.
Siebe JanSenior Backend Engineer at Make School
At Make School, I had the pleasure to work with Lucas for a year now. Inside the team, he has been a major asset on many projects and contributed to the overall success of the team. Lucas is hard-working, has a wealth of experience, seeks to always improve and learn, and holds his work to a high standard. In addition to his technical talents, his positive, we're-in-this-together mindset, flexibility, and willingness to help out wherever necessary are a real asset
Royce BrooksSenior Frontend Engineer at Make School
Lucas played an instrumental role in my career by ramping me up in Ruby on Rails. Lucas' work was always a pleasure to review and learn from thanks to his commitment to write clean, easy to read and testable code. His extensive knowledge and willingness to lend a helping hand made working with him fun and rewarding.
Samuel BrandãoCofounder and Developer at Lets Events
Lucas is a prolific and problem-solving oriented developer. Focused on getting things done, he is able to provide both elegant code and smart solutions, balancing the scales between performance and maintainability. An excellent communicator, he is always able to keep calm and think pragmatically.
Jordan ArnsenSoftware Engineer at Make School
I was the lead (aka only) backend developer on the engineering team when Lucas first joined Make School and he was senior to me in total years of experience. I appreciated how Lucas and I were always able to teach and learn from each other and our different areas of expertise (his deeper background in tech and my knowledge of our codebase). Even as a fully remote team member, Lucas' strong communication skills always ensured that the team and stakeholders had clear and up to date information. When I later transitioned off of the engineering team, I knew that things were in great hands with Lucas.
Mona DesaiDesigner at Make School
Working with Lucas has been an absolute pleasure. His dedication to his craft is apparent in everything that he does. Lucas not only cares about clean code but has also shown great understanding and empathy for the users that ultimately will be using the tools that he builds. Lucas strives to find solutions that best fit the problem at hand without compromising on the end product. I know without a doubt that Lucas will add great value no matter where he works.
Tiago Romero GarciaIT Director at Avenue Code
Lucas is a great and fairly-judged developer. He is clever, faithful and always striving for the best approach, balancing out his front-end and back-end skills. He is also engaged in performing a great team work. I really appreciated having the opportunity of working with Lucas and I definitely recommend his work to every employer or project.
Alexandre QueirozIT Manager at Avenue Code
Lucas is a great professional which I was luck enough to work with in the same company. We had few interactions within projects, but awesome interactions within the company and working for the same client. I could notice Lucas as very resourceful helping colleagues on solving small issues and perfectionist on creating solutions for problems. In a project we worked together, I could notice the persuasive capacity of Lucas on showing the best solution to tackle the problem we were facing as well as most adequate technology to be used.

I had the pleasure of working with Lucas Arruda at Senergy. He has consistently demonstrated a strong work ethic and a dedication to sucess! He worked actively to resolve customer/partner issues in a timely manner. Lucas is creative and an excellent multitasker.
