- Led end-to-end containerisation initiative using Docker and Kubernetes, enabling horizontal auto-scaling and zero-downtime deployments that reduced deployment lead time by 40% and significantly improved infrastructure resource utilisation.
- Optimised Oracle Database performance through advanced SQL query tuning, data-modelling refactoring, and index optimisation, reducing average query response time by 20% for high-volume transactional workloads.
- Produced Architecture Decision Records (ADRs), solution design blueprints, and multi-year technical roadmaps aligned with Ericsson's digital transformation strategy, facilitating executive-level stakeholder approval and delivery governance.
- Coordinated with enterprise architects, product owners, and multi-vendor global teams to ensure solution delivery within scope, timeline, and quality benchmarks, maintaining continuous alignment with strategic business objectives.
Cloud Solution Architect / Middleware Developer
Cognizant Technology Solutions
11.2019 - 06.2022
- Architected and delivered cloud-native enterprise solutions on AWS, integrating Spring Boot microservices with AWS Lambda for serverless backend processing, reducing infrastructure operational overhead by 35% and delivering measurable FinOps cost savings.
- Designed serverless workflow orchestration using AWS Step Functions to manage complex multi-step Lambda execution pipelines, improving end-to-end processing reliability and reducing manual intervention by 50%.
- Architected secure, multi-tier AWS VPC environments with IAM policy frameworks and subnet segmentation, achieving zero post-deployment security incidents and full compliance with enterprise cloud security and governance policies.
- Designed and implemented scalable file-storage and retrieval architecture on Amazon S3, supporting high-volume enterprise document-management workflows with cost-efficient data-access patterns.
- Led deployment and governance of application environments on AWS Elastic Beanstalk, implementing blue-green deployment strategies and auto-scaling policies that minimised release risk and improved service availability.
- Engaged directly with enterprise clients to elicit requirements, define solution architecture, and present technical proposals, driving successful on-time delivery of 5+ cloud transformation projects using Agile/Scrum methodology.
- Authored solution design documents, architecture diagrams, and technical specifications serving as authoritative blueprints for development teams and client sign-off, accelerating team onboarding and reducing rework.
- Mentored and coached junior engineers on cloud-native and microservices architecture best practices, contributing to measurable improvement in team capability and delivery quality.
Integration Architect / TIBCO Developer
TIBCO Software Inc
03.2018 - 11.2019
- Architected and developed enterprise integration solutions using TIBCO BusinessWorks 5 (BW5), designing SOAP and REST web services that connected 10+ disparate backend systems — including legacy applications, databases, and external SaaS platforms — within a formal SOA governance framework.
- Led SOA-based integration design for a large-scale enterprise middleware platform, enabling seamless data exchange and end-to-end process orchestration across business-critical applications, reducing manual data-handling effort by 40%.
- Designed robust message-transformation flows, comprehensive error-handling frameworks, and intelligent retry mechanisms, achieving 99.9%+ message-delivery reliability across mission-critical enterprise integration pipelines.
- Implemented high-availability middleware configurations and proactive monitoring strategies, reducing unplanned platform downtime by 30% and ensuring continuous SLA compliance for enterprise clients.
- Collaborated with cross-functional and cross-vendor delivery teams on production incident management, performing structured root-cause analysis and implementing preventive architectural improvements that enhanced long-term platform stability.
- Contributed to SOA governance documentation, integration design-pattern libraries, and architectural best-practice standards subsequently adopted across the wider middleware practice, enabling faster onboarding of future integration programmes.
Application Engineer / Software Engineer
Atos
