The project entailed a strategic shift from traditional server-based architectures to a serverless computing model for a mid-sized fintech company looking to reduce operational overhead and increase scalability. This transition aimed to leverage cloud services to automatically manage the scaling and provisioning of resources, enabling the company to focus more on core product development and less on infrastructure management.

January 2023 - October 2023

Conducted a thorough analysis of the existing infrastructure and designed a roadmap for transitioning to a serverless architecture.

Selected appropriate cloud services (e.g., AWS Lambda, Amazon DynamoDB, API Gateway) that aligned with the company's operational requirements and business goals.

Developed prototypes to demonstrate the feasibility and benefits of serverless computing for key components of the existing system.

Led a specialized team of cloud engineers and DevOps experts to execute the migration strategy.

Coordinated with cross-departmental teams to ensure minimal disruption to ongoing operations and maintained a clear channel of communication regarding project progress.

Applied agile project management techniques to handle the iterative deployment of serverless functions and services.

Personally coded critical aspects of the serverless setup, particularly around deployment automation and event-driven data processing functions.

Ensured best practices were followed in the software development lifecycle, including code reviews, version control, and automated testing.

Created detailed documentation on new workflows and operational procedures post-migration.

Led the successful migration of over 50 distinct services to serverless computing, achieving a reduction in infrastructure costs by 55%.

Engineered solutions that improved system scalability, handling up to 1,000,000 concurrent users without the need for manual intervention in scaling.

Reduced latency by 40% for end-user transactions by utilizing edge computing capabilities provided by the serverless framework.

Pioneered a shift in the company culture to embrace cloud-native and serverless-first approaches for future development initiatives.

Optimized resource utilization, eliminating idle server time, and aligning operational costs directly with actual usage.
