Jack LaSota

Freelance C# Developer at Toptal since August 24, 2016
Although Jack has enough of a computer science background to turn algorithms into code, most of his skills originated from an indie puzzle game that he wrote alone. He learned that he had to be a perfectionist about best practices in order to avoid slowing to a crawl on large projects. He developed another successful (niche) major project: a front-end only single page web app, wearing every hat and talking to the users about what they needed. Click to continue

Steven Norton
Testimonials
“The Toptal process was very organized, personable, and professional. They get to know you and your project idea, and then quickly provide you with several of the world's best developers, who will work hard to achieve your vision. I found a great developer in only a few days and was able to turn my idea into a functional product.”
Ben Woratyla
CEO @ Book Swap
“As a growing startup, finding top-notch engineering talent at affordable rates is one of the biggest challenges. After being frustrated with unreliable local contractors in New York, we turned to Toptal. We worked closely with Michal in Poland for 5 months and were thrilled with the results. Michal was an outstanding engineer who communicated flawlessly and took control of our project in ways that far exceeded my expectations. I give Michal and Toptal my highest endorsement and will continue to use and recommend them to anyone looking for software engineering talent.”
David Baker
Founder @ Spins.FM
“Toptal’s ability to rapidly match our project with the best developers was just superb. The developers have become part of our team, and I’m amazed at the level of professional commitment each of them has demonstrated. For those looking to work remotely with the best engineers, look no further than Toptal.”

“In our 2 years of operations this is by far the most enjoyable and productive working relationship we have had with a developer. I plan on continuing to recommend Toptal's services to other entrepreneurs I run into.”
David Sawyer
CEO @ TSOLife
“Andrea is doing an amazing job. I don't think we could have gotten a better person. He is fun to work with, he thinks out of the box, and he is extremely knowledgeable in what he is going. He not only does an excellent job, he also helps our company to differentiate our business model further (e.g. making our app offline-capable). I would recommend Andrea as well as Toptal any time to any friend.”
Pascal Girardat
Co-Founder / CEO @ Lifestage Solutions AG
“Sergio was an awesome developer to work with. Top notch, responsive, and got the work done efficiently.”
Dennis Baldwin
Chief Technologist and Co-Founder @ PriceBlink
“We had a great experience with Toptal. They paired us with the perfect developer for our application and made the process very easy. It was also easy to extend beyond the initial time frame, and we were able to keep the same contractor throughout our project. We definitely recommend Toptal for finding high quality talent quickly and seamlessly.”
Ryan Morrissey
CTO @ Applied Business Technologies, LLC
“Toptal is amazing. Sourcing and interviewing candidates has always been incredibly cumbersome and difficult - and usually takes weeks or months to find the right people. With Toptal, we had 5 candidates in 2 days that were all perfect for the job. They made the scheduling of interviews easy and straightforward and we were working with a top-level developer within 2 weeks. I love you, Toptal.”
Ian Fosbery

Michael Milton
VP of Engineering @ SLANTRANGE
“To take advantage of Toptal's capabilities, we actually remodeled the way we do our work. We develop pseudo code with some code fragments that we send to our Toptal developer, who has a specific task set. The work is then further processed by the next group of Toptal engineers. It's been very efficient and we've seen a massive improvement in our development speed.”
