Sajith A.Private profile: Upwork shows its earnings only to signed-in members, so we check it every few weeks, not daily. MRR here is a rough estimate (Upwork's six-month earnings ÷ months active). Last read Nov 5, 2026.

I am an Integration professional with 15+ years of IT experience and nearly 12 years in the integration domain, leading architecture and delivery for enterprise-grade, cloud-native integration platforms. My focus is on designing and governing integration architecture that is secure, scalable, resilient, and observable across hybrid and cloud environments. I work hands-on, from architecture to implementation, translating business capabilities into API-led and event-driven integration solutions, primarily using the WSO2 integration stack. I bring strong expertise in: Integration Architecture and API Strategy: API-led connectivity, domain-driven integration boundaries, service decomposition, mediation patterns, contract-first API design, versioning strategy, and lifecycle governance. Enterprise Integration Patterns and Protocols: REST, SOAP, JMS, HTTP/S, XML, JSON, MQTT, async messaging, transformation/orchestration, protocol bridging, and legacy-to-modern modernization. Cloud-Native Platform Engineering: Kubernetes architecture, production-grade manifests, Helm chart and release management, ingress and traffic management, load balancing, security hardening, and operational reliability. DevSecOps and Delivery Architecture: Git branching/tagging strategy, GitLab CI/CD pipeline design across environments, release automation, quality gates, and deployment standardization. Infrastructure and Automation: Ansible and Terraform for repeatable, policy-aligned provisioning and configuration management. AWS Architecture and Security: Strong knowledge of AWS ecosystem design and implementation, including secure network patterns and controls with Security Groups, AWS WAF, Shield, Inspector, encryption at rest/in transit, and operational visibility through CloudWatch, CloudTrail, AWS Config, and Systems Manager. Event-Driven and IoT Integrations: Kafka, MQTT, and IoT-oriented messaging for scalable and loosely coupled integration landscapes. I am equally comfortable defining architecture standards and executing deeply technical delivery. I work effectively with cross-functional teams, drive integration governance, and ensure platforms remain maintainable, compliant, and future-ready.
