Founder Johnpaul Guminkiriza was born into a family of engineers, and construction has been his passion since childhood. Whenever something was being built at home, he was there helping. What hooked him was the transformation: something that looked worthless turning into something magnificent. That feeling is why he is still in construction today. He started work as a site engineer in his first year at university in 2011, was promoted to project manager and then to director, and is a member of the Project Management Institute (PMI). He graduated in January 2015 with a BSc in Civil Engineering, worked with government, consultants and private-sector clients, and managed building construction. In 2016 he started the company in Kampala, Uganda as Jopie Engineering Group. He later added an MBA specialising in construction management. After migrating to Canada, the same company was registered in Ontario in 2026 as Jopie Construction Group, bringing hands-on construction experience and a real commitment to planning and communication to homeowners and businesses in the Hamilton area.
Why we started Jopie
Johnpaul started Jopie because he saw a gap between showing how construction should be done and actually doing it. He watched projects miss their deadlines because of poor scheduling, and he believed he could do better but was always limited. Using the planning methods he practises as a PMI member, such as mapping which tasks depend on which, Jopie plans every job so the right work happens in the right order. Read why renovations run late and how scheduling prevents it.
How we work: we plan before we build, and we learn from every job. We keep a lessons-learned register and ask after each phase what we did well, what to improve and how to be more efficient, then apply it on the next project. Our payment schedule is simple and written into every contract: 30% before we start, 40% at the midpoint, 30% when the work is complete. Read more in our guides.
We're a new company in Ontario. Too many construction projects go over budget and past deadline because no one is truly managing them. We aim to run every job — large or small — with real planning, clear communication and one team accountable for the result.
Today we're a general construction contractor serving the Hamilton area, handling complete projects from planning through to the final finishes. We self-perform many of the trades in-house — drywall, painting, tiling, flooring and more — and manage the rest, so our clients deal with one accountable team instead of juggling subcontractors.
Meet the founder
Johnpaul is a civil engineer (BSc) with an MBA in construction management and has worked in construction since 2011. He's a member of the Project Management Institute (PMI) and upholds its Code of Ethics and Professional Conduct. He's hands-on with every Jopie project, from the first walkthrough to final sign-off — not a name on a website.
Real planning behind every build
What we aim to bring to every job is straightforward: a written scope, a realistic schedule, an honest budget, and one point of contact who actually keeps the project on track — instead of a verbal promise and a shrug when things slip.
Our founder is a member of the Project Management Institute (PMI), the world’s leading association for project, program and portfolio management professionals, and the way we plan and track every job reflects that discipline.
For you, that means honest estimates, realistic timelines, tight coordination between trades, and a single point of contact from start to finish.
