Worked with Arkema France to conceptualise and construct a centralized message mapper and data synchronisation system, enabling seamless communication between various SAP application services and different external services. These services utilised diverse data formats, including JSON, XML, CSV, and BOSON. Our solution featured an event-driven architecture implemented using AWS Step Functions, incorporating mapper templates and Lambda functions. These templates were stored in Amazon S3 and dynamically applied based on the incoming data format. This project was developed as a pure backend service following Infrastructure as a Service (IAAS) principles, utilizing AWS CDK, and was coded in TypeScript with a Node.js runtime.

I served as a module lead in the legal management domain, taking on a diverse range of responsibilities:1. Access Management and Microservices Migration: I was responsible for creating, designing, and maintaining Access Management while orchestrating the transformation of a monolithic ERP system into a new, microservices-based Software as a Service (SaaS) ERP system. This transition required expertise in implementing multitenancy, which I accomplished using Cognito and its pre-token generation trigger. In addition, I oversaw the integration of a Multi-Schema RDS database and employed API Gateway Custom Authorizer.2. Voice-to-Text Conversion: I led the design and implementation of voice-to-text conversion using AWS Transcribe, enhancing the user experience. To make this system even more user-friendly, I implemented Transcribe Custom Vocabulary, which allowed users to define their own abbreviations for expanded text. An article I wrote on this topic was published by AWSTips on Medium.3. Real-Time O365 Integration: I took the lead in designing and implementing real-time integration with O365 for calendar events. This integration enabled the automatic recording of user events within our system when they created, accepted, or rescheduled meetings. This design was purely event-driven and utilized webhook Lambda, SQS, and Microsoft Graph API integration, offering a high scalability of around 100 queries per second (QPS).4. Decoupling for Improved Performance: I was involved in the decoupling of various long-running processes to accommodate the API Gateway's timeout limit of 30 seconds. This included tasks such as uploading large files and processing them asynchronously. Users would be notified once these processes were completed using services like SQS, SNS, and Event BridgeMy extensive experience in these areas reflects a deep commitment to delivering innovative solutions and ensuring efficient, scalable, and reliable systems.
