Development process

Our agile development process

Standardised, transparent, and efficient. We ensure every project is delivered on budget and on time.

  1. In-depth requirements & architecture planning

    We don’t rush the first line of code. Our system architects explore your business logic with you, define a lean MVP feature list, and plan the underlying database structure.

  2. Professional UI/UX prototyping (Figma)

    Before development begins, we deliver high-fidelity interactive Figma prototypes. Preview every button interaction and screen transition on your phone to ensure the design matches your expectations 100%.

  3. Agile code development

    Full-stack development with a staging environment where you can review progress weekly and provide real-time feedback — keeping the project firmly on track.

  4. Multi-platform launch & ongoing maintenance

    After rigorous stress testing and security audits, we handle Apple and Google store submission and provide unlimited upgrades and maintenance through our remote developer outsourcing monthly plans.
