Asfar I.
Sr. Solution Architect | AWS Cloud, SaaS, Subscription & Payments
I am a Senior Solution Architect and Cloud Engineer with 10+ years of experience designing, modernizing, and scaling enterprise-grade SaaS, subscription, and payment platforms. I specialize in building secure, highly available, cloud-native systems that handle millions of transactions, complex integrations, and strict compliance requirements. My background spans telecom, media, digital services, and payment platforms, where I’ve led architecture and delivery for systems processing 10M+ transactions annually, supporting subscription lifecycles, digital payments, carrier billing, and multi-region deployments. I work comfortably with both technical and business stakeholders, translating product requirements into scalable, production-ready architectures. What I Do Best - Design end-to-end cloud architectures (AWS / Azure) for SaaS and enterprise platforms - Build and modernize subscription, billing, and payment systems (cards, wallets, carrier billing, vouchers) - Architect microservices and event-driven systems with high availability and fault tolerance - Lead platform migrations from third-party vendors to in-house, cloud-native solutions - Optimize cloud costs, performance, and reliability without compromising scalability - Implement PCI-DSS–compliant security architectures, API security, IAM, and encryption - Deliver clear technical documentation, diagrams, and operational runbooks for long-term maintainability Enterprise & SaaS Experience At OSN (Dubai), I served as Solution Architect for an in-house Subscription & Payment Platform (SDP) powering SVOD services. I designed a microservices-based, highly available architecture, integrated multiple regional and global payment methods, and led security and compliance initiatives resulting in 100% PCI-DSS audit compliance. My work reduced cloud infrastructure costs by 45–50%, improved transaction success rates by 18%, and cut involuntary churn by 22% through intelligent retry and recovery mechanisms. I’ve also delivered serverless and cloud-native solutions using AWS Lambda, API Gateway, DynamoDB, SQS, ECS, and EventBridge, led data migrations, integrated third-party systems, and stabilized production platforms under real-world load. Earlier in my career, I worked on IoT and healthcare-related systems, enterprise software products, and cloud migrations, giving me a strong foundation in distributed systems, performance optimization, and secure data handling. How I Work - I bring a solution-architect mindset rather than just writing code. I focus on: - Clean, scalable system design - Security and compliance from day one - Cost awareness and operational efficiency - Clear communication and documentation - Building systems that are easy to operate, extend, and audit I’m equally comfortable designing architecture from scratch, reviewing and fixing existing systems, or acting as a technical lead/advisor for founders and engineering teams.
