What we offer
Complete digital solutions tailored to your needs
Specialized solutions across four core digital domains
What We Build
Custom Web Applications & SaaS Platforms
Explore Next.js Development →A custom web application is software built specifically for your business workflows — unlike off-the-shelf tools that force you to adapt your processes to their limitations. We build web applications on Next.js and React, two technologies that power the world's most demanding digital products.
SaaS (Software-as-a-Service) platforms are web applications delivered via subscription. If you have a product idea — a booking system, a client portal, an analytics dashboard, or a marketplace — we architect and build it from database to deployment. Our typical SaaS projects include multi-tenant authentication, role-based permissions, subscription billing integration, and real-time data processing.
Admin dashboards and internal tools represent another major category: systems that help your team manage customers, inventory, orders, or operations. We build them with the same quality standards as public-facing products.
Cross-Platform Mobile Apps with Flutter
Explore Flutter Development →Flutter is an open-source UI framework created by Google that allows developers to build natively compiled applications for iOS and Android from a single codebase. This means you get two apps for roughly 60-70% of the cost of building them separately — without sacrificing performance or user experience.
We chose Flutter as our primary mobile technology after evaluating React Native, Kotlin Multiplatform, and native development. Flutter's advantage is a consistent rendering engine (Skia/Impeller) that produces pixel-perfect UI on both platforms, a rich widget ecosystem, and excellent performance for complex animations.
Our mobile projects span fitness tracking apps, invoice management tools, field service platforms, and B2B portals. Every app goes through UI/UX design, prototype validation, development, QA testing on real devices, and App Store / Play Store submission.
Business Process Automation
Explore Business Automation →Business process automation (BPA) means replacing manual, repetitive work with software workflows that run automatically. A business that manually exports reports every morning, manually copies data between systems, or manually sends routine emails is wasting valuable human time on work that software can handle in seconds.
We specialize in n8n — an open-source workflow automation platform that lets us connect any application to any other. Unlike Zapier or Make, n8n can be self-hosted on your infrastructure (important for GDPR compliance), supports unlimited workflow executions, and handles complex conditional logic that generic tools can't manage.
Typical automation projects: invoice generation triggered by CRM events, automated onboarding email sequences, cross-system data sync (CRM ↔ accounting ↔ project management), weekly reporting dashboards auto-generated and sent via email, and AI-powered customer inquiry routing.
Our clients report 40-80% reduction in time spent on manual tasks after automation implementation.
E-Commerce & Marketplace Development
Explore Web Development →Modern e-commerce goes far beyond a product listing with a checkout button. High-converting online stores require fast page loads (every 100ms matters for conversion rates), smart search and filtering, abandoned cart recovery, personalization, and seamless payment integration.
We build custom e-commerce solutions when standard platforms like Shopify hit their limits — typically for businesses with complex product configurations, B2B ordering workflows, custom shipping logic, or integration requirements with ERP/warehouse systems.
For marketplace projects (where sellers and buyers transact), we architect multi-vendor systems with seller dashboards, commission handling, dispute resolution, and review systems. These projects typically run 3-5 months and require careful database design to handle concurrent transactions.
Every technology choice is deliberate, not fashionable
Technology We Use & Why
Next.js
Next.js is a React framework that adds server-side rendering, static site generation, API routes, and optimized image handling out of the box. It's maintained by Vercel and used by companies including Netflix, TikTok, Twitch, and the OpenAI website. We use Next.js for projects where SEO matters (server-rendered HTML is immediately readable by search engines), where performance is critical (Partial Prerendering, React Server Components), and where the application needs to scale without infrastructure complexity.
Flutter
Flutter uses the Dart programming language and compiles to native ARM code — not to a JavaScript bridge like React Native. This produces animations that run at 60-120fps, smooth scrolling, and reliable behavior across different Android manufacturers and iOS versions. The Flutter ecosystem has matured significantly since Google's initial 2018 release. Today, it supports web, desktop, and embedded targets in addition to mobile — making it a genuine cross-platform solution.
n8n
n8n (pronounced "n-eight-n") is an extendable workflow automation tool. The core advantage over SaaS automation tools: it runs on your server, your data never leaves your infrastructure, and there are no per-execution fees that make automation expensive at scale. We build custom n8n nodes for systems that don't have official integrations, write JavaScript/Python code nodes for complex data transformations, and design multi-branch workflows that handle errors gracefully.
Why Senior-Only
Adrijan founded Samioda after 8+ years building web and mobile applications for companies across Europe. His background spans React/Next.js architecture, Flutter development, and backend systems. He leads every project technically, not just commercially.
Most agencies hire a mix of junior, mid-level, and senior developers — then assign seniors to sales calls and juniors to your project. We made a different decision.
Samioda works with a small, senior-only team. Every developer has 5+ years of production experience. This means:
Faster delivery. Senior developers don't spend time debugging basic issues or learning core concepts on your project. They've built similar systems before and know where the traps are.
Better architecture decisions. The choices made in week one (data model, authentication strategy, caching approach) determine how much your project costs to maintain in year two. Senior judgment here prevents expensive rewrites.
Direct communication. You talk to the person writing the code. No account managers playing telephone between you and a development team.
Honest estimates. We know what we don't know. When something is genuinely complex, we say so — rather than giving an optimistic estimate and then explaining overruns later.
This approach means we take fewer projects simultaneously. We'd rather do three projects very well than seven projects adequately.
Why Companies Choose a Croatian Development Agency
Croatia's EU membership provides legal and contractual certainty that offshore development often lacks. GDPR compliance, clear IP ownership, invoicing in EUR — these aren't small details when you're building software that handles customer data.
The cost-to-expertise ratio is genuinely favorable. Croatian senior developers have the same technical education and practical experience as their counterparts in Western Europe — at significantly lower daily rates than Germany, Austria, or the Netherlands.
Timezone alignment with Central Europe means overlapping working hours without the communication delays that create problems in offshore arrangements. We're available during your business day, not the opposite.
Zagreb has produced a strong developer community over the past decade, with active professional networks and a culture of continuous learning. The local market's competitive nature means Croatian developers maintain high standards to remain employable.
How a Project Begins
The typical starting point is a 30-minute discovery call — no obligations, no sales presentation. We want to understand your problem before proposing a solution.
After the call, we send a written summary of our understanding, an initial scope proposal, and a fixed-price estimate. If the estimate aligns with your expectations, we sign a simple contract and begin with a paid discovery sprint.
The discovery sprint (1-2 weeks) produces a technical specification, an architecture diagram, and a revised final estimate. This document becomes the contract for the development phase — no surprise additions.
We work in two-week sprints with a demo at the end of each sprint. You see progress every two weeks, not after six months of silence. Changes to scope are handled through a transparent change order process — always discussed before any work begins.
