Web Development

We build for the web from first principles: semantic structure, performant CSS, and JavaScript that solves problems rather than creating them.

  • Responsive design for all screen sizes
  • Performance-first — fast loading, smooth interactions
  • SEO-ready structure and clean semantic HTML
  • Accessible and standards-compliant
  • Custom CMS integration when needed

Mobile Game Development

We have shipped Android games on Google Play and know what it takes to build one that actually works — on real devices, for real players.

  • Native Android and Unity-based game development
  • Play Store submission and compliance
  • AdMob integration and monetization setup
  • Firebase Analytics for player insights
  • Post-launch support and updates

Product Development

We help turn ideas into real digital products — thinking through the problem, designing a clear UX, engineering something reliable, and shipping it properly.

  • Problem definition and idea validation
  • UX design and user flow planning
  • Full-stack engineering and testing
  • Launch planning and deployment
  • Post-launch iteration based on real feedback

Approach

Discovery UX Design Prototyping Engineering QA Testing Deployment Iteration
🔬

R&D

We invest time in understanding what's next — exploring new tools, frameworks, and approaches, not for novelty but to find things worth building.

  • Technology scouting and evaluation
  • Prototype development and proof-of-concept
  • Feasibility analysis for new product ideas
  • Internal tooling and automation research
  • Cross-domain learning and application

Approach

Exploration Benchmarking Prototyping Analysis Documentation Application

Why Work With Us

What makes Sefdek different from a generic agency.

📦

We've Shipped Real Products

We build what we recommend. Our apps are live on Google Play. We know what it actually takes to ship — not just in theory.

🤝

You Talk to the People Building It

No account managers, no intermediaries. Direct communication with the team doing the work — faster decisions, fewer misunderstandings.

Four Capabilities, One Studio

Web, mobile games, product development, and R&D under one roof. Less coordination overhead, more execution speed.

🔧

Post-Launch Isn't an Afterthought

We stay involved after delivery — updates, fixes, and support are part of the relationship, not an upsell.
