Hi, I'm Sergey.
I build websites and web apps, and I make sure they're fast, secure and run reliably in the cloud. I've been doing this for more than ten years. I write the code myself, and I care about the parts most people never see: performance, security, and how the thing holds up a year after launch.
In early 2024 I founded SM SOFTWARE in Milan, Italy, bringing more than ten years of experience in development, cloud and security under one roof. As CEO and lead developer, I stay involved in every project from the first conversation to launch and beyond, so the person who plans your project is the same one who builds it. We design and build custom websites, web applications and cloud infrastructure, with security and performance built in from day one, not bolted on at the end.
From idea to launch
Got an idea?
Let's build it.
Ideas are the easy part.
Turning them into something people actually use? That's where the magic happens.
Whether it's a new website, a custom web app or moving your business to the cloud, tell me what you have in mind. I'll tell you how I'd build it and what it would take.
Let's make it happen.
Frequently Asked Questions
Custom websites, web applications, and cloud infrastructure on AWS, Google Cloud or Azure. I also do security reviews of existing web apps, so if you already have something live and want to know how solid it is, that's a good place to start.
Yes. I start by reviewing the code, hosting and setup, then tell you plainly what's in good shape, what needs fixing, and what I'd change first. You don't need to start from scratch to work with me.
Yes, that's exactly where performance and security experience pays off. I find the cause, fix it, and close the gaps that let it happen, so you're not dealing with the same problem again next month.
It depends on what you need, so I don't publish a price list. After a short call I send you a written quote with the scope, timeline and price, so you know exactly what you're getting before any work starts.
A business website usually takes a few weeks. A custom web app or a cloud migration takes longer, depending on the scope. You'll get a realistic timeline in the quote, not an optimistic guess.
Yes. I work remotely with clients anywhere, in English or Italian.
Your choice. I can take care of hosting, updates, monitoring and fixes, or hand everything over to your team with documentation so you're not dependent on me.
Of course. If your idea or product isn't public yet, I'm happy to sign an NDA before we discuss the details.
Mostly Next.js and React on the front end, Laravel and PHP on the back end, WordPress when it's the right tool, and AWS, Google Cloud or Azure for hosting and infrastructure. I pick the stack based on the project, not the other way around.
