Being the Kafka Architect and owning the Kafka shared package we implemented, there was a requirement to use a different sdk library than the one that was previously used. However its performance was not good enough for the desired/necessary metrics of the business flows. I took the responsibility of finding bottlenecks and improving the performance. I used my Kafka Developer Certification knowledge to change our consumption strategies and leverage the batch method, with caution that this would cause idempotency issues when an entire batch is replayed. We heavily tested the new strategies used, different load testing, happy path testing including testing different error scenarios. We confidently released the new version of the shared Event Bus package to production, and we have not seen any event related issues since. The new performance turned out to be about 100 times faster than what it was previously.

Led the performance optimizing of all key functional business flows during Performance Testing, including reducing our Database footprint by combining and decreasing the number of indexes on some of our Tables (i.e from 22 down to 5 indexes for one of our tables) while performing query analyzations on all store functions. I was trusted to take the role of the Owner/Architect of the Kafka shared package we built and I also became the most knowledgeable backend developer on the project. While managing a team of offshore developers, I wrote up wiki documents to keep good practice standards and useful things to keep in mind while implementing new features on an event driven system (i.e a PR checklist for all developers to respect in order to reduce the amount of review and rework on PRs). I have also taken a mentorship role in assigning complex saga implementations to the other developers and reviewing their work. Highly involved during SIT and UAT to patch things on the fly. I owned the User Management platform of this project, redesigning the User Data Model because of some flaws I pointed out. Our solution was integrated to Azure’s Active Directory using the MS Graph Explorer API.

Implemented from scratch a low-latency, highly available and performant application that is widely used by Financial Institutions across Canada. Played an integral role in the Microservice team. Used Node.js and Jest for Unit Tests. Event-driven Architecture using Azure Event Hubs. Enforced Idempotency throughout the microservices. I was trusted to design and implement Sagas for the key business flows and I received great mentorship from some of the technical architects on this project. Implemented and owned a database-client that would be used across all microservices. Also worked on other shared packages such as the event-client, logger, config, schema-validator.

Integrated our client’s Salesforce CRM solution with external APIs essential their business flows. Implemented Single Sign-On using OAuth2.0 as our authentication scheme that allows a user to log in with their platform’s existing ID credentials. Software was written in Java and I reinforced the writing of unit tests in my team of 4 Developers.

Cofounder of Spap allowing everyday athletes & tournament organizers to connect and set up their games in the most interactive and efficient way. Developing the mobile app single handedly using Django for backend and React Native in order to deploy on both Android and IOS. Uses AWS Relational Database Services – MySQL. Deployed on AWS Lambda. Lambda functions and database hosted inside a Virtual Private Cloud. Network Address Translation instance is used to allow outbound communication with the public internet, which enables Apple Push Notification Services for iPhone and Firebase Cloud Messaging for Android.

Full stack web developer - Developed solutions for clients. Along with another intern, developed two web applications for startup clients, one of them being a social media platform for pets. The Frontend was developed using React.js and Redux, and the Backend using Node.js and Express. The web app included features like chat using socket.io, push notifications, and is mobile friendly including a Progressive Web App option. The project was managed on Trello. Pull requests were reviewed by our supervisor and peer reviewed with the other intern.

I created a gateway software to enable automatic and continuous Wifi communication between a software and a sensor through Xbee chips. I was also in charge of storing sensor data for the smart city project in Montreal. I wrote a python program that parses and unifies raw sensor data in a generic way for all different types of sensors, and uploads it to a database I created on Azure’s CosmosDB, along with a UI program that visualizes the data with graphs.

I created a file parser that converted log files to XML files. I then created a wrapper in C# to a block of functions to make writing scripts for their software product easier. I also learned about numerical computations and I created a program on Octave that fits a rational polynomial with the Bernstein basis to a set of data points which could be used to make parts of their software faster.
