Our Services

Our services cover the full journey of a tech product – from idea to implementation to protection. Whether you need a specific capability or the complete package, we ensure each solution benefits from our combined expertise in development, AI, and cybersecurity.

Custom App Development

Bring your idea to life with our end-to-end app development service. We build modern web and mobile applications from scratch – designing intuitive user interfaces, writing robust backend code, and ensuring everything runs smoothly in the cloud. Our team follows agile methodologies to deliver results fast and adapt to your feedback, ideal for startups iterating on their product.

Whether you need an MVP to attract investors or a full-scale application ready for thousands of users, we have the experience to make it happen. Quality and scalability are at the core of our process, so the software we deliver will grow with you. Plus, because we're security-minded from the start, your app's architecture will be reliable and safe.

Includes:

  • UI/UX Design: Crafting user-friendly interfaces and engaging user experiences.
  • Web & Mobile Development: Building responsive web apps and native or cross-platform mobile apps (iOS/Android).
  • Cloud Deployment & DevOps: Deploying your application on reliable cloud infrastructure, with CI/CD pipelines for continuous updates.
  • Maintenance & Support: Ongoing improvements, performance tuning, and support as your user base grows.

AI-Powered Development

Unlock the power of artificial intelligence in your applications. Our AI development service adds intelligent capabilities – from chatbots that converse naturally, to recommendation engines, to predictive analytics dashboards. We specialize in agentic AI systems: AI 'agents' that can make decisions and carry out tasks autonomously.

Instead of just responding to single prompts, these agents can plan and execute multi-step workflows. This means solutions like virtual assistants handling customer inquiries end-to-end, or automation tools streamlining internal processes without constant human oversight. We stay updated with the latest in ML and AI frameworks (LLMs, GPT-based systems, data analytics) to choose the right approach. The result: AI features that deliver real value, making your product more efficient, insightful, and competitive.

Includes:

  • AI Consultation & Strategy: Identifying high-impact AI opportunities for your operations or product.
  • Custom AI Development: Building and training models for specific needs (e.g., recommendation systems, predictive models).
  • Integration of AI APIs: Seamlessly integrating third-party AI services (NLP, vision, voice recognition).
  • Agentic AI Workflows: Designing autonomous agents for multi-step tasks (e.g., automated support email handling).
  • Data Pipeline & Training: Setting up data collection and training pipelines for continuous AI improvement.

Cybersecurity for Startups

Protect your product and customers with our cybersecurity expertise. Startups face the same threats as large companies but often lack dedicated security teams – that's where we help. Our professionals embed best practices into your development lifecycle and ensure the right safeguards are in place.

We perform thorough security assessments, identifying vulnerabilities before attackers can. From secure code and encryption to firewalls and monitoring, we cover your needs. We also know proving security is vital. If you aim for certifications like ISO 27001 or need a SOC 2 audit, we guide you step-by-step, establishing policies, documentation, and technical controls. Think of it as getting your startup "enterprise-ready". You'll be safer and able to show partners you take security seriously. We act as your fractional security team, ensuring growth isn't derailed by cyber risks.

Includes:

  • Security Audit & Penetration Testing: In-depth application testing with detailed reports and remediation guidance.
  • DevSecOps Integration: Implementing security checks within your CI/CD development pipeline.
  • Cloud Security: Securing cloud infrastructure (AWS, Azure, etc.), including access control and monitoring.
  • Policy Development: Creating security policies (access control, incident response) aligned with ISO 27001/SOC 2.
  • Compliance Readiness: Hands-on help with evidence collection and documentation for audits; liaison support during audits.
  • Ongoing Monitoring & Support: Options for continuous security monitoring or periodic check-ups.
