Services

  • Full-stack custom development (Web & Mobile — Node.js / React / React Native)

    We build scalable web and mobile apps using Node.js, React, and React Native, delivering secure back-end services, robust APIs, and high-performance user experiences for enterprise and transactional systems.


    Benefits: Fast MVPs, production-ready code, scalable APIs, multi-platform support.

  • Architecture consultancy & Cloud engineering

    We design resilient, scalable, and cost-efficient platforms using cloud-native architectures, microservices, and CI/CD. We also advise on migration, security, and integrations to ensure reliable performance in real-world conditions.

    Benefits: Lower technical risk, predictable scalability, faster releases.

  • UI/UX & Product discovery

    We run evidence-based discovery: user research, stakeholder workshops, prototypes and usability testing. Our UX and product teams define the experience, flows and feature prioritisation that drive user adoption and measurable business metrics. The result is a validated roadmap and high-fidelity prototypes that reduce rework and align stakeholders.

    Benefits: Higher adoption, reduced development waste, validated product roadmap.

  • QA (Quality Assurance) & Test Automation

    Quality is integral to delivery. We provide test strategy, automated unit/integration/e2e testing, manual exploratory testing and performance/regression testing integrated into your CI pipelines. Our approach reduces production defects and supports safe, frequent releases.

    Benefits: Continuous quality, predictable releases, faster recovery from issues.

  • Data & Lakehouse consultancy

    We design modern data platforms — ETL/ELT pipelines, lakehouse architectures, data governance and business intelligence. Our data engineers enable reliable analytics and reporting, underpin AI initiatives and ensure data is trustworthy, discoverable and secure.

    Benefits: Single source of truth, faster insights, governed data for analytics/AI.
