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

"Toptal is killing it, it kind of owns this market."
Andrew Ross Sorkin Reviews Toptal
"Tech companies simply cannot find the quality employees they want to hire. The solution: Toptal."
Liz Claman´s Review of Toptal
Toptal in the press
“Despite accelerating demand for coders, Toptal prides itself on almost Ivy League-level vetting.”
Selina Wang
“Toptal allows corporations to quickly assemble teams that have the right skills for specific projects.”
Steven Norton
Testimonials
“We needed a programmer to help push a project over the finish line, and I figured -- best case -- Toptal would find someone who would come in and complete a few tickets. Instead, Sergio blended right in with the team and made significant progress after mere days of ramp-up. He even offered to take his laptop with him on vacation in case we had a customer issue with his code! He surpassed my expectations, and then some.”
Bryan Adams
CTO @ Healthsense
“We really enjoy working with Toptal. The experience has been very positive, and we'd recommend it to anyone seeking developers on-demand.”
Jeff Kerr
CEO @ CaseFleet
“We have been incredibly happy with our Toptal experience. Initially a skeptic, the process to find and recruit a fabulous iOS developer was very easy. Rather than sifting through hundreds of CVs, we saw two and hired them. They have worked effectively, getting up to speed incredibly quickly and have almost become part of the team. We would definitely use Toptal again. ”
James O'Day
Co-Founder @ Pearlshare
“Through Toptal, we were able to find and select a senior engineer who is both very professional and easy to work with. The quality of matching that Toptal enabled has been crucial to our success, was at a fair price, and came with a much appreciated, risk-reducing trial period.”
John Olsen, Director
Director @ Bingo Solutions
“Toptal is a great resource for startups with ever-changing product roadmaps and budgets. Within 8 business days of our first conversation, we had highly skilled and reasonably priced Toptal developers working for us. It has been an empowering experience for our company to start working with Toptal.”
Chris Clark
CEO @ BirdieFire
“One of their engineers from Colombia has joined our team as a full-time developer for more than 6 months, sometimes flying to work on-site in New York City with us. He is one of the best developers I've ever worked with.”
Carter Cleveland
CEO @ Artsy
“I really enjoyed my experience with Toptal. Searching for a developer was both painless and engaging, and the first match was a perfect fit! Toptal is a fantastic way to find talented developers for small or large aspects of your project.”
Willem Shepherd
Creative Director @ Mookieyams
“Toptal was the best thing to happen to my web app. Initially, I hired a team of freelancers from India through another freelancing website—which was a nightmare. In fact, it was so bad that I had to start again from scratch, which is when I found Toptal. The experiences were like night and day. It was so refreshing to get partnered up with a quality developer that I could trust due to Toptal's extensive screening process. I will only use Toptal from now on and highly recommend you do the same.”
Chris Holtzhauer
CEO @ HootRecruit
“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.”
Laurent Alis
Founder @ Livepress
“I struggled for weeks with a Youtube API-specific problem and couldn't find anyone to solve it. Toptal immediately identified the right consultant who took the time to investigate the issue and resolve it quickly. The process was seamless and I will continue to use Toptal with any other issues that arise.”
Rohit Gupta
CEO @ Bollyshake
“My business relationship with Toptal has been nothing short of terrific. From reviewing my project with their team to choosing a highly-talented developer, and all the way through releasing our application, it has been an incredibly smooth and successful experience.”
Gary Craig
Senior Analyst @ NetApp
“As a small company with limited resources we can't afford to make expensive mistakes. Toptal provided us with an experienced programmer who was able to hit the ground running and begin contributing immediately. It has been a great experience and one we'd repeat again in a heartbeat.”
Stuart Pocknee
Principal @ Site Specific Software Solutions
“In Higgle's early days, we needed the best-in-class developers, at affordable rates, in a timely fashion. Toptal delivered! ”
Lara Aldag
CEO @ Higgle
“My experience with Toptal has exceeded expectations. I needed to quickly find a front-end developer, and the first person they recommended was a perfect fit. A month later, I needed an iOS developer and they delivered again. I'm incredibly impressed with the quality of the people in Toptal's network and how quickly I was able to find a match for my needs.”
