Founded in Niš, Serbia — we are a team of specialized software engineers with a track record in demanding industries. Every engagement we have ever won came through a recommendation.
Smartnet Technologies is a software development company based in Niš, Serbia. We work with companies in Europe and the United States as an independent IT vendor or as an embedded part of their engineering teams.
Our business model is simple: deliver exceptional quality, earn client trust, grow through referrals. We have never relied on cold outreach — every project we work on came through a recommendation from a satisfied client.
We are not an all-purpose agency. Our teams consist of specialists — developers who are deep experts in their specific areas, not generalists who do a bit of everything. We actively participate in product development, architecture decisions, and problem-solving — not just code delivery.
Cloud-native development, AI integration, embedded systems, and healthcare software are where we focus and where we are strongest.
Each team is built from domain experts. The developer who writes your .NET API has done it for years — not months.
We contribute ideas and architectural solutions — not just lines of code. This is what moves projects forward and creates real value.
No layers between you and the engineers. Clear communication, fast decisions, no internal bureaucracy slowing things down.
We adopted cloud-native development and AI tooling early. We don't wait for technologies to become mainstream.
We aim to earn your trust over the long run — not to maximize the scope of a single project at the expense of the relationship.
Daily, weekly, and monthly status reports. WBS and SOW definition from the start. No surprises on timelines or scope.
Experienced engineers in leadership positions — not just managers.
Software engineer by background. Leads business development and client relationships. Directly involved in every engagement and available for communication at any stage.
Senior architects define project scope, lead technical decisions, and provide hands-on mentorship. Deep experience with large-scale cloud and enterprise systems.
Specialists in .NET, frontend, mobile, embedded systems, AI, and QA. 80%+ hold computer science degrees from accredited universities in Serbia.
I had the pleasure of working with Saša during our time building Workango and WorQeez, where he played a key role as CTO and technical lead. Saša consistently demonstrated strong leadership, managing development teams effectively while helping turn ambitious concepts into scalable production systems. What stood out most was his forward-thinking approach to cloud infrastructure and engineering. At a time when many companies were still early in their cloud adoption journey, Saša designed and implemented a highly scalable Azure-based architecture that was genuinely ahead of its time. He also led the development of complex backend systems including automated messaging, notification engines, and ETL-driven data processing pipelines. Beyond the technical side, Saša was instrumental in delivering integrations with major UK and international HR/job platforms, helping drive product functionality and growth.
He combines deep technical knowledge with a practical problem-solving mindset, and I'd confidently recommend him to any company looking for a capable CTO, architect, or engineering leader.
I have had the opportunity to collaborate with Saša on software development initiatives where he played a key role in designing and delivering effective technology solutions. What impressed me most about Saša is his ability to combine deep technical expertise with a strong understanding of business needs. He is not only focused on writing software, but on creating solutions that bring real value to the organization. Saša is a reliable professional with excellent analytical skills, a structured approach, and the ability to manage complex challenges. He communicates clearly, works efficiently with different stakeholders, and consistently demonstrates ownership and responsibility.
I would confidently recommend Saša to any organization looking for an experienced software engineer and a professional partner who can help transform ideas into successful products.

Niš is Serbia's second-largest city and a major university center with state-accredited IT and computer science faculties. The influx of engineering graduates is constant, and the depth of mathematical and engineering education is exceptional.
The city has a long tradition in engineering and science — Serbia is the birthplace of Nikola Tesla and Mihajlo Pupin. That heritage shows in the rigor and problem-solving ability of the developers we attract.
Serbia has the highest percentage of English-language speakers in Southeast Europe, and local business culture aligns naturally with Western European and American norms — making collaboration intuitive from day one.
At GMT+1 — the same timezone as Berlin, Paris, and Zurich — we share more than 4 hours of working overlap with the US East Coast daily, and full working-day overlap with all of Western Europe.
What we use daily and have mastered over many years of project delivery.
Real architecture decisions, production trade-offs, and technical patterns — from telemedicine platforms to multi-provider data layers.
