Developed and deployed an advanced audio generation system for Shortform.com, leveraging ElevenLabs TTS to create natural, human-like narrations for text articles. Designed a pipeline to process and chunk Markdown files into optimized text formats, enhancing the quality and flow of the audio output. This feature significantly improved user engagement by delivering a seamless auditory experience that complements the written content.

Python, Flask, VueJS, AWS

One of the main contributors out of the two, to re-design and implement a new version of the data pipeline that simplifies the architecture and allows faster evolutions. This pipeline is handling petabytes of data daily and used in one of the strategic products of Amazon Advertisement organization. My team leveraged Iceberg and other technologies and refactored the existing Spark jobs to a cleaner and simpler design. This project reduced the number of job applications from 15 to 1 for a module.

Python, Scala, AWS, Spark/PySpark, ETL, PyTorch

Led the redesign and implementation of the next generation of Acceptto's SSO microservice to make it horizontally scalable and highly available. The old SSO module was a web server that should be run and maintained on the customer site. The new version was designed to run in the cloud and connect to the customer's user directory using an agent. This project reduced the customer onboarding time from days to hours.

AWS, Terraform, Ruby, VueJS, JavaScript

Created a solution for Acceptto that allowed their backend to communicate with customers' ActiveDirectory. I managed the project (team of two) and contributed to the development directly. It was done in two phases and successfully executed with customer compliments. The final architecture removed the need for firewall configurations and load balancing on the customer side.

Go, Ruby, VueJS, TypeScript, JavaScript

Designed and implemented a policy orchestration engine that allows customers to define their rules and condition to customize a core IAM solution software behavior. For example, customers can dynamically define policies to ask for MFA in addition to passwords when the user is logging in from a specific location or specific time of day, or a specific risk profile associated with the user. In addition to a UI, it allows power users to write their own predicates and policies. This feature provided a competitive advantage for the company in the industry which led to at least two successful accounts.
