As a committed and multifaceted professional, my journey has spanned both the vibrant world of hospitality and the demanding field of construction, enriched by my academic progression from a BSc Level 5 towards a Level 6 qualification. My career began amidst the buzz of a Michelin-starred eatery, where I quickly mastered the art of stellar customer service and seamless teamwork, evolving from an eager Commis Waiter to a proficient Waiter. With the onset of the COVID-19 pandemic, I pivoted to the construction realm, starting as a General Labourer. My dedication to growth led me to acquire essential certifications like SSSTS, NVQ Level 2, and First Aid Level 3, paving my path to becoming a Drylining Fixer. Presently, I apply my broad skill set as a Maintenance Handyman, focusing on the meticulous care and repair of properties to uphold their functionality and appeal. Renowned for my relentless work ethic, flexible nature, and meticulous attention to detail, I thrive in settings that demand ingenious problem-solving and clear communication.

I was very satisfied with the results of VFurb's external renovation and decoration work, which took 3 weeks in total, extended due to rain. Dragos worked six days a week to keep me informed of progress, answered all my questions, and identified practical solutions to unforeseen problems, supported by detailed costings . He was always present to supervise his team of 2-4 workers, and personally completed the most complex roofing, piping and guttering jobs himself to a high standard.
