I'm ambitious and dedicated to whatever comes my way. I always find creative solutions to tackle issues that arise with clients. Due to my perfectionism, these solutions are usually the most optimal resource and time wise. I'm very well able to communicate clearly with clients to understand their needs and translate them well into the final high quality product, being also able to suggest brainstorm and suggest ideas to save resources and improve the product's final features and usability. Most Importantly, I am truly passionate about my work, and find pleasure in being challenged and put to my limits to find unorthodox and out of the box fixes and features for the product, I'm not looking to just fit deadlines and pass by tasks, I'm hoping to deliver the best possible product that best fits the criteria requested by customers
