Available for software architecture consulting & fractional CTO engagements

Shaji Kurian – Senior Software Architect & Fractional CTO
helping engineering teams build systems that scale without chaos.

I’m a hands-on architect and former Staff Engineer with 30+ years of experience designing backend systems, AI-driven platforms, microservices, and cloud infrastructure. I partner with founders and CTOs who need senior technical leadership without hiring a full-time executive.

Software Architecture • System Design Java • Spring Boot • Microservices AWS • Kubernetes • Redis • PostgreSQL AI Agents • Platforms & Integrations

Where I help: validating architecture, de-risking scaling plans, and unblocking teams so they can ship faster with confidence.

Architecture & Fractional CTO Services How we can work together

I partner with founders, CTOs, and engineering leaders who need senior technical guidance for architecture, scaling, and delivery. Most collaborations start with a focused architecture review and grow into a 4–12 week fractional CTO or advisory engagement.

Fractional CTO / Principal Architect

1–2 days per week of senior technical leadership. I help translate business goals into a clear technology roadmap, guide architectural decisions, and support your engineering lead or CTO with an experienced second opinion.

Best for: early-stage startups, fast-growing teams, or businesses in technical transition.

Architecture & System Design Review

A deep, objective review of your current or proposed software architecture: APIs, data models, microservices, reliability, observability, security, and scaling strategy — with pragmatic recommendations you can implement immediately.

Deliverables: written review, risk assessment, and a live walkthrough session with your team.

Legacy Modernisation Strategy

Modernisation plans that move you from monoliths or legacy stacks to modern cloud-native architectures using incremental patterns, not disruptive rewrites. Focused on risk management, rollout safety, and business continuity.

Approach: strangler fig patterns, progressive decomposition, and staged migration plans.

Backend & Platform Engineering

Hands-on design and implementation of backend services, domain models, and integrations for web and mobile products. Strong emphasis on clean contracts, observability, and operational excellence from day one.

Tech focus: Java, Spring Boot, REST/GraphQL, PostgreSQL, Redis, Kafka, and event-driven systems.

Cloud & DevOps Foundations

Setting up robust AWS environments, CI/CD pipelines, monitoring, and incident-ready operations so your platform can scale safely. I help you choose sensible defaults and avoid over-engineering.

Tools: AWS, Docker, Kubernetes, Jenkins, GitHub Actions, CloudWatch, and related ecosystem.

Technical Mentoring & Code Review

Regular architecture and code review sessions with your engineering team. We improve design, push for better engineering practices, and create a culture of thoughtful system design instead of quick hacks.

Ideal for: teams with strong energy and ownership but limited access to senior mentors.
