John Hajjar posted thisLeaving a job and a group of people that I consider friends and family is one of the hardest decisions I've had to make. Thank you to everyone at UNFI that helped me become a better teammate and engineer - I have more appreciation for everyone than I can express with words. You all mean a ton to me, and I look forward to grabbing a drink or three anytime you're in the Providence area! That being said, I'm looking forward to a new adventure and set of challenges at Brown University. Ready to roll my sleeves up and get to work!

John Hajjar liked thisJohn Hajjar liked this#BrownLovesProvidence is a month-long effort to give back to the local community that supported us when it mattered most. On December 13, 2025, and in the days and weeks that followed, the people of Providence and Rhode Island showed Brown the true meaning of community. First responders and state officials worked around the clock to help make us safe. Businesses provided warm meals and kind words. Neighbors opened their doors to those who needed food or a place to sleep. Community partners and local alumni ensured safe passage for our students leaving campus. Our collective gratitude to the city has no time limit, but we hope Brown students, faculty and staff will give, shop and volunteer locally from Feb. 14 through March 16, 2026 to help express our appreciation for the selfless aid the Providence community provided when we needed it most. ❤️ https://lnkd.in/en72e-xG

John Hajjar reacted on thisJohn Hajjar reacted on thisBrown community members flexed their muscles for a cause in early November at the 21st annual Bench Press for Cancer on the College Green, organized by the Bears football team. Originally established to support Class of 2005 member Lawrence Rubida, who died of cancer during his senior year, the fundraiser has generated more than $200,000 for the Oncology, Wellness, Lifestyle and Cancer Survivorship Clinic at the Miriam Hospital in Providence. This year’s six-hour event in front of Sayles Hall drew spectators and participants, who took their turn at the bench press while receiving cheers and encouragement from student-athletes on the football team.

Brown University sophomore Delaney O’Dea grew up watching “Jeopardy!” with her superfan grandmother and got the urge to compete after visiting a live taping when she was just 7 years old — a moment she recounted on stage with host Ken Jennings when she turned her childhood dream into “Jeopardy!” reality this week. She nailed the final trivia question on Wednesday, Oct. 15, winning the episode and netting $18,600. “I didn’t really realize what was happening in the moment,” O’Dea said. “It was so surreal that I think I didn’t fully process it until I watched the episode.” It was a victory not just for O’Dea, but for Brown’s Department of Classics. A classics and medieval cultures concentrator at Brown, O’Dea took the lead with a Daily Double on “Transylvania,” using Latin skills from her studies at Brown to correctly translate the region’s name. O’Dea continued her “Jeopardy!” run on Thursday and came in second place, joining the ranks of Brunonians — including Justin Bolsen, a member of Brown’s Class of 2026 — who’ve buzzed their way into the show’s history.

Had a great time speaking at the CyberPathway student chapter last week including a repeat session on the topic titled “The Four Planes Model: Data, Control, Management & Observability — and Where Security Hooks In.” We explored how every network, security, and cloud design and operations can be viewed through these four lenses — Data Plane – packets & segmentation Control Plane – routing, policies, and identity Management Plane – change, automation & governance Observability Plane – logs, metrics, and feedback loops One of the most engaging moments was when the group applied the model to analyze the recent AWS outage, mapping where each plane contributed to event, detection, control, and recovery. And perhaps the biggest compliment of all: a repeated attendee, saying he “wanted to extract more information” from the discussion. That kind of curiosity and hunger to learn is exactly what our industry needs. I believe mentoring isn’t just about sharing knowledge, but about sparking new ways of thinking. If our next generation of engineers start designing and securing infrastructure keeping fundamental design principles, we’re already shaping a more resilient digital future. A big Thank You to ISC2 New Jersey Chapter Bryon Singh and the CyberPathway Chapter Team for hosting this event. Looking forward to more such conversations bridging academia and enterprise practice. #CyberPathway #Mentorship #NetworkArchitecture #SecurityArchitecture #ZeroTrust #CareerInCyber #ArchitectureMindset #TechCommunity
