François Bonin
Java Developer in Paris, France
Member since October 4, 2016
Since 2000, François has been building software systems with various technologies. After having been awarded the Microsoft MVP title four years in a row for his deep knowledge of the .NET platform, he discovered a passion for building and monitoring distributed systems as an Amazon senior engineer. During that time, he worked with teams across continents and developed an affinity for cloud software.
François is now available for hire

The most amazing...
...design I’ve created was for an automated enterprise bus that interoperated hundreds of services in various styles, data formats, & protocols with no coding.
Employment
Experience
- Mobile Staff and Job-tracking Application (Development)
This is an enterprise mobile phone application that was distributed to thousands of staff and customers. The aim was to allow the employees of the client company to receive assignments on the road, report on their activities, and keep the customers informed on the state of the jobs they are paying for.
I designed the architecture and led the development team behind this application.
Customers are kept up to date via an SMS sent from the back-end servers via the Twilio API, while the staff receives notifications through their devices via the AWS Simple Notification Service (plugged into Google Cloud Messaging, and AWS SQS for fanning out to the appropriate collaborating staff). - Automated Enterprise Bus Service for Distributed Systems (Development)
I designed and built a system enabling different service owners to provide a formal description of their service (name, list of endpoints and operations, input parameter schemas, output object schemas) using standard description grammars (WSDL, WADL, and more), authentication schemes, and providers.
In return, the system ensures the discovery, interoperation (with the appropriate sequencing of operations and marshaling of input/output parameters) across protocols and service styles; without the need to write a single line of code. - Network Performance Monitor (Development)
Utilizing a C++ written native layer that intercepts socket-level events, I designed and built a cross-platform component that computes statistics on network performance (errors, port utilization, data rates, and more), buffers them, correlates them to method calls within the code of a currently running a .NET or Java application and sends the augmented stack traces to a remote collection server using an optimized binary transfer protocol.
- Neural Network Driven Customer Recommendation Engine (Development)
Using TensorFlow, I built the code that runs a model to examine past offerings, contrasts them with customer engagements (purchases, cancellations, and more), and time periods to determine the optimal (leading to the most purchases and least cancellations) product offering on a future date. The resulting code produces accurate result for dates up to two weeks in the future using a few months of training data
