Every thriving community has members whose energy, creativity, and commitment help shape it into something extraordinary. In the InterSystems Developer Community, one such member is @Henry Pereira — a developer, open-source contributor, contest winner, and true believer in the power of collaboration.
👏 Let’s take a closer look at Henry’s remarkable journey and his continuing legacy in the InterSystems ecosystem.

Henry’s story with InterSystems products began more than 20 years ago, when, as a young intern, he first worked with InterSystems Caché (version 4, no less) and wrote plenty of MUMPS code. Life took him in other directions for a time, but in 2016, fate — and technology — brought him back. Joining BPlus Tech on February 2nd of that year, Henry quickly rediscovered InterSystems technologies and was impressed with how far they had evolved. Only three days later, while searching for open-source projects, he discovered the Developer Community and found inspiration in the work of @Dmitry Maslennikov, whose code helped shape Henry’s approach to Caché ObjectScript.
Henry’s first contribution to the Developer Ecosystem was CosFaker, a project initially inspired by a JavaScript library but soon evolving into something unique. It was also the subject of his first community article. From there, Henry became increasingly involved in contests, collaborations, and open-source projects.
One highlight was his participation in the RestForms project alongside @Eduard Lebedyuk and @Alberto Fuentes, which proved especially meaningful during a challenging time in his personal life. Another standout moment came in 2021, when Henry entered the InterSystems Security Contest solo with his project iris-disguise.
In recent years, Henry has competed as part of the Musketeers team with @José Pereira (“the brain”) and @Henrique Dias (“the heart”), while humorously dubbing himself “the itch in the nose.” Their project iris-medicopilot earned second place in the Vector Search, GenAI, and ML Contest, bringing Henry professional visibility and real-world client interest in vector search technology.
Henry deeply values the Developer Community’s warmth, responsiveness, and professionalism, noting the absence of hostility and the high level of organization. He’s a fan of the Global Masters gamification program and is continually impressed by the brilliant ideas and innovations produced in community contests.
Henry’s advice to newcomers? Get involved. Contribute, participate, and treat every project as both a learning experience and a personal showcase.
Outside of coding, Henry spends his weekends playing electric guitar in a band, cherishes time with his children, and actively serves his local community, particularly its youth. Each year, he challenges himself to learn a new programming language, a testament to his insatiable curiosity. His family and faith keep him grounded, reminding him of the importance of rest alongside growth.
Henry’s journey, from his first MUMPS code to international contests, from personal reinvention to community leadership, embodies the spirit of the InterSystems Developer Community. Through his technical contributions, collaborative spirit, and heartfelt presence, he has become a creative force and an inspiration to all who have the privilege of working alongside him.
🙏 Join us in celebrating Henry for his dedication, ingenuity, and the warmth he brings to the Developer Community.
