Recent Testimonials

I had the great pleasure of working closely with Coleton, and I can confidently say he's an outstanding professional and a pleasure to work alongside. Coleton consistently demonstrated his technical expertise and proposed plans for improving code architecture.

One of Coleton’s key strengths is his communication—he’s able to explain complex concepts clearly and ensures that everyone on the team is aligned. He’s also a quick learner, staying on top of the latest trends and technologies, and finding creative ways to incorporate them into his work.

Beyond his technical skills, Coleton is a team player who is always willing to step up and help others. His positive attitude and calm demeanor in challenging situations make him a leader by example.

I highly recommend Coleton for any role or project. He brings both technical skill and a great team-oriented mindset to everything he does.

Senior iOS Software Engineer

Coleton is an exceptional problem solver and engineering partner. We worked together on a project when he was new to Glo and he immediately dug in to identify the best strategy for implementation and uncovered several additional opportunities to optimize our performance beyond the initial scope. He's a creative, scrappy engineer and brings a lot to the table.

Kristen James
Senior Product Manager
Glo Digital

I am pleased to recommend Coleton Gorecke as an excellent and professionally consistent iOS Engineer for any engineering team looking to grow. Throughout our time working together Coleton consistently demonstrated strong technical prowess, solid judgment, an ability to deliver with exceptional velocity, and a consideration for both long and short term decision making architecturally. To date Coleton has been one of my strongest engineers in terms of effectiveness immediately after onboarding.

Within the first month Coleton was able to not only support our flagship product launches, and build towards immense pressured deadlines, but additionally take lead on iOS to get us through the finish line to launch ahead of schedule. As Coleton quickly adapts to complex projects, he takes ownership, and efficiently delivers high-quality solutions, all the while ensuring stakeholders across product, engineering, marketing, and leadership are informed on the progress and blockers at a consistent basis.

Beyond his delivery and collaboration skills Coleton is very thorough at tracking his work, providing multiple solutions when blocked, understanding the product from a customer lens, and connecting with engineers and leaders alike to foster buy-in to decisions made.I strongly recommend Coleton for any iOS engineering role.

I believe any company will massively benefit from his presence, and I would go as far to say he is a role model for other engineers to emulate within a given team.

Andreas Can
Director of Engineering

Coleton is very self driven and his tenacity with programming is beyond impressive. I’ve watched him go from a self taught programmer to a full-fledge professional iOS developer in a short amount of time.
