About me


My name is Cristina (aka Cree) Lester. I’m a Full Stack Developer, UX designer and Illustration, with 8+ years of experience with front-end web development, site reliability engineering, performance analysis and optimization, system management and monitoring. I worked as a freelancer first, and then for different companies using diverse platforms, tools, and languages.

During those years I mainly worked as front-end developer and web master, but in the recent months I found myself being more interested into back-end development, so I decided to invest some time into learning Node and I wrote my first RESTful API. I didn’t abandon front-end development though, in fact to complete my skillset, I wrote a client application using React and I immediately fell in love with it. What I loved about it is how easy is to render and manipulate data with React and its hooks.

Then I explored Test-Driven-Development techniques to implement a Progressive Web Application with React, which revealed new exciting ways of programming that made me eager to learn more about it.

I am a well-trained teammate who loves to share ideas, prioritize communication in order to achieve goals within the set deadlines.

I enjoy being challenged and working on projects that require me to step outside of my comfort zone, so my motto is “Whatever comes up, I’ll figure it out!”. Learning how to learn is the best lesson I’ve ever received.

I'm also a bass player, skilled illustrator, gourmet cook, weight lifter, yoga student and Muay Thai kickboxer. I spend the rest of my free time petting my cat Mochi, listening to (and sometimes making) music, and hanging out with my best friend and partner in life, Joe.

What they say about me

Cree is one of the best and brightest coworkers that I have had the pleasure of working with, she brought years of experience and expertise to every project that we have worked on. She always came through hitting every deadline without compromising on quality. Every interaction that we have had has been nothing short of pleasant, I would 100% recommend any company looking to add an engineer to give her a shot.
- Daniel Namkoong Former Coworker, Software Engineer
I met Cristina (Cree as I've known her) when I joined the ranks of Site Reliability Developers at a marketing firm. She had held that role long before I got there and from the beginning she was extremely helpful in onboarding and stabilizing me. Cree and I share a love of growth and learning, this was most ​evident when I saw her refactor code that no one else wanted to touch or when she brought in fresh techniques to solve age-old site-optimization issues. I highly recommend Cree as a valuable technical resource to anyone who wants a reliable, ambitious, and dedicated team member. She was wonderful to work with and will be a boon to any team she joins.
- Dani Amsalem Former Coworker, Marketing Developer at SignUpGenius
While working through multiple projects on the CareerFoundry full-stack developer program, Cristina demonstrated adept learning abilities grasping and applying various tools and techniques, her pace of learning enabled her to complete her program two months earlier. In her tasks, she showed curiosity, finding creative ways to solve problems in her code. She communicated frequently and proactively, often seeking clarification on tasks and feedback. Most of all, she showed a strong desire to continually excel in her work across the entire application stack.
