Saad Saeed

Founder & CEO @ Crumb

“Within its first nine weeks, the app received 8,000 users and a 4.7-star rating. The platform is well-designed and hasn’t had many bugs. AMS LLC is fast and efficient at building new features as well as taking scope changes in stride. Expertise and responsiveness are hallmarks of their work.”

Will von Behr

Founder @ Urbs Travel

“I got an amazing product that was exactly what I visioned when I first sat out & drew the first plans up. The two areas that I think where Stan & his team particularly excel:
first is attention to detail (…) & secondly the kind of support after they’ve provided after the app been largely complete – I’m sure the number of teams just do the bug work & leave it but they are [AMS team] always on hand to answer any questions really at any time of day which is incredible.
So I’d encourage anyone who wants to build any sort of product use Stan & his team cause it’ll accelerate your business and make your life a whole lot easier. “

Doug Scibilia

Foounder & CEO @ SQRK – Squaker

“Before choosing AMS I’ve hired a firm out of India – they gave me a great price, great timeline (…). And after close to a year, they told me they couldn’t get the project done.
Then I’ve started to talk with Stan from AMS. I hired them, they quoted me 8 weeks to get this project done, well, it’s 8 weeks later – the project is done. And now I just have nothing but a great thing to say about the company – they were on time, great communication and just great people there. I’d 100% recommend AMS for any web development or app development project that you have out there, they’re just fantastic.”

About us

Stan Sakharchuk

Co-Founder & CEO

I’ve seen how typical development agencies operate: too many clients, not enough time, prioritizing their own gains over the client’s results. It is my mission to ensure we at AMS always stick to our values: obsession with our clients’ success, laser focus on a select few businesses and staying at the forefront of mobile development to help our clients beat the market.

Evgeny Mahnach

I am a scientist, turned Software Engineer turned Senior IT Consultant. I am the bridge between your business objectives and development strategies. I am strategic and pragmatic to the bone, so I’ll never waste your time or money. I believe meritocracy shall reign so you’ll always get my honest perspective. My intention is to be the last developer you’ll ever need to partner with.

Ilia Stakhno

Chief Project Manager

I’m obsessed with processes. Life is a huge process to going from point A to point B to point C and so on. My job is to make sure we’re following best practices when developing the software solution for your business. Jira, Scrum, Agile, daily standups, grooming & presentation sessions are my best friends. If you don’t yet have a clear development process on your project – we’re coming to you!

Elizabeth Ermakova

UI/UX Designer

Bad UI/UX shall not pass. Following modern guidelines, tying up the UI solutions to your target users’ base, carefully applying best user experience practices is my day-to-day duty. Perfect UI/UX is one of the most important things that can differentiate your app from the tight competition in the marketplace. Ask me how to design RIGHT!
