What We Do

Everything a business application needs over its lifetime: the architecture behind it, the engineering that builds it, the intelligence that makes it more useful, and the care that keeps it running.

01

Application Development

Custom web applications, business systems, portals and APIs, built around your requirements and designed to integrate with the systems you already use.

02

Solution Architecture

Architecture for new systems and for evolving existing ones: technology choices, integration design, scalability, security and long-term maintainability, documented so your team can build on it.

03

Enterprise Software Engineering

Enterprise applications and API-driven platforms engineered for reliability, performance and quality, and to fit seamlessly into existing business ecosystems.

04

Application Modernisation

Moving legacy applications to modern architectures and platforms step by step, without disrupting the business that depends on them.

05

AI Engineering & Integration

AI-powered applications, LLM integrations, retrieval-augmented generation (RAG) and intelligent features added to existing software, turning AI capabilities into practical business value.

06

Autonomous AI Agents

Autonomous and multi-agent systems that reason, collaborate and execute complex workflows, combining AI-driven autonomy with human oversight where it matters.

07

Cloud & Platform Engineering

Secure, scalable cloud-native platforms, infrastructure automation and cloud modernisation, on public cloud, private cloud or your own servers.

08

Application Security

Security designed into the software we build, plus AI-assisted threat detection and security intelligence for the applications businesses already run.

09

Forward-Deployed Engineering & Support

Working alongside your team inside your environment, and keeping applications healthy after launch: maintenance, updates, performance tuning and continued development.

How We Work

Good software starts with understanding the business it serves. Every engagement follows the same discipline, whether it is a new application, an architecture review or an AI integration.

  1. 01

    Understand

    We start with your business, your users and your constraints, and agree what success looks like before anything is built.

  2. 02

    Architect

    We design a solution that fits your environment and will still make sense in five years, and document the decisions behind it.

  3. 03

    Build

    We deliver in clear steps, communicate openly throughout and keep quality, security and performance in view at every stage.

  4. 04

    Support & Evolve

    We stay involved after launch, maintaining and improving the software as your business and its needs change.

Quality and sustainability. Software that is well designed, reliable and maintainable, not just finished.

Clear communication. You always know where the work stands and what comes next.

Security by design. Security is considered from the architecture onwards, not added at the end.

Long-term partnerships. Many engagements continue for years, well beyond the first release.

The Founder

Prabhu Daya

AI Engineer & Solution Architect

Prabhu Daya is an AI engineer and solution architect with close to two decades of software engineering and architecture experience, spanning enterprise software engineering, solution architecture and modern AI technologies.

Almost a decade of that experience was spent in Switzerland, working for multinational financial and insurance companies: environments where software is expected to be reliable, secure and well documented, and where systems handle sensitive customer and financial data every day.

Years of working with and for European clients have built a practical understanding of their technical expectations, engineering standards and business requirements. That experience runs through every OjjO engagement.

  • Close to two decades in software engineering and architecture
  • Almost a decade in Switzerland
  • Multinational financial and insurance companies
  • Long-term work with European clients
