A Career Built Around Engineering and Business.
My career started in engineering and technology, working with medical systems, automation, and technical projects. Over the years, I expanded into business development, construction, and real estate.
Today, I’m involved in several businesses in Florida, combining my technical background with hands-on experience managing projects, working with clients, and building companies. I believe in staying involved, paying attention to the details, and finding solutions that work in the real world.

Real Estate From a Different Perspective.
Buying, selling, or investing in real estate involves important decisions. My role is to help you make those decisions with clear information and a practical perspective.
As a REALTOR® and Certified General Contractor in Florida, I understand both the real estate process and the construction factors that can affect a property’s value. From its overall condition to its renovation potential, I can help you recognize details worth considering before making a decision.
I’m here to guide you through the process, from the first showing to closing.

Your Home Away From Home in Miami.
Enjoy a private home with a pool, an outdoor BBQ area, and plenty of space to spend time with family or friends. A comfortable place to relax, have fun, and experience Miami at your own pace.
We’re just two blocks from Calle Ocho (SW 8th Street), close to Miami International Airport, Little Havana, and many of the attractions that make Miami special.
“The home was beautiful and well decorated. Beds were comfortable and house was clean. I’d definitely stay again just to get the opportunity to enjoy the absolutely beautiful pool area… the host communicated with us the entire time to make sure we were in safe ❤️, that alone deserves 1000 stars.”
“Very pleasant having a pool and the separate room away from the house, very spacious… lots of activities in the home, for kids and adults, very comfortable and enjoyable. Would most definitely rent again!”
“very beautiful home! in a quiet neighborhood and very responsive and accommodating host & co hosts”

Frequently Asked Questions
Everything You Need to Know Before Getting Started.
1. What areas do you serve as a REALTOR®?
I work throughout Southeast Florida, including Miami-Dade, Broward, Palm Beach, Martin, and St. Lucie counties, as a Real Estate Sales Associate with Best Options Realty, Inc.
I work with buyers, sellers, and investors through every step, from the property search to closing.
2. What makes you different from other real estate professionals?
Besides being a REALTOR®, I’m an engineer and a Certified General Contractor. When we tour a property, I look beyond price and location to its condition, its systems, and what it would take to improve it.
That helps you spot potential issues and understand a property’s real potential before you decide.
My construction experience complements, but does not replace, an independent professional inspection.
3. Do you work with real estate investors?
Yes. I help you evaluate each opportunity based on the purchase price, renovation budget, rental potential, and long-term value.
My construction background is especially useful for properties that need work and for value-add projects.
4. What construction services do your companies provide?
Through Top Tier Contractors, Inc., Top Tier Roofers, Inc., and Subterra Infrastructure, Co., we provide residential, commercial, and infrastructure construction services.
That includes general construction, renovations, roofing, HVAC, plumbing, underground utilities, excavation, trenching, and Horizontal Directional Drilling (HDD).
Each company works within the specialties authorized by its licenses.
5. Do your construction companies work outside Miami?
Yes. Our companies hold Florida state-certified contractor licenses, which allow us to work statewide within each licensed specialty, subject to local permitting requirements.
We are based in Miami and evaluate each project based on its location, scope, and complexity.
6. How can I verify your professional licenses?
You can verify my contractor licenses on the official website of the Florida Department of Business and Professional Regulation (DBPR).
Search by my name, the company name, or any of the license numbers listed on this website.
