Backend Software Developer for AIsaac Cybersecurity Solution with the mission to make the Event Collector Service more efficient within the AIsaac Solution Backend. Tasked with speeding up the set-up process of simulating high-density threats.

• Slashed the set-up process from 1 week to just 1 hour by employing C# to design a highly efficient and customizable software solution to allow programming the number of security events per second.
• Increased the number of simultaneous events handled by the cybersecurity solution by 20% by increasing the efficiency of the Event Collector module by designing a scalable solution in the context of continuous data input by automatically scaling up & down the number of services based on cache load.

Skills: C# / .Net, MS SQL, Entity Framework, REST, WCF, Test-Driven Development (NUnit, Xunit, MSTest), Microservices, Azure.

Backend Engineer of an ERP Solution rewriting in .NET the Acquisitions and Timekeeping modules of the Backed Software. Tasked with reducing acquisition time and increasing the sell-through rate.

• Reduced the time spent on acquisitions by 20 man-days a month for a particular company with ~ 10000 selling items, by designing the server side of the “Acquisitions” module, by implementing it as a REST API serving the WEB & mobile user interfaces.
• Increased the sell-through rate by 20% by designing a custom-tailored solution to avoid inventory getting out of stock, by putting together insights from the database raising an alarm 10 days before a piece of inventory must be ordered so that it won’t get out of stock.

Skills: C# / .NET, MS SQL, Entity Framework, REST API, JSON, Node.js, Typescript.

Back-End Engineer adding support for several IoT Devices. Contributed to the increase of Data IO rank to #1 provider of automated security provisioning by significantly contributing to improving the existing solution to support several most trendy IoT devices by designing a highly-flexible secure provisioning algorithm.

• Contributed to Data IO becoming NXP’s #1 security provisioning solution provider by understanding & solving the business needs of the client, by designing a “Counterfeit Device Detection” capability for the NXP SE050 device, and by participating in the design of a plug-and-play dynamic user-interface.
• Reduced the time of NXP SE050 programming by 20%, by increasing the speed of the SE050 programming algorithm, by efficiently operating all CPU cores by using .NET Parallel Programming.

Skills: C# / .NET, Python, JSON, Test-Driven Development (NUnit, Moq), Cryptography.

The client, an important player in the telecommunication industry, was struggling to keep up with the market competition due to lacking a competitive development team.

• Decreased the effort needed to sustain the VRRP feature from 5 developers/year to 1 developer/year by improving software architecture while leading a fast-paced team of 5 developers, redesigning VRRP to run on a different task, and by raising the priority for VRRP heartbeat packets through the protocol stack.
• Contributed to winning a DoD contract of 30 million $ by implementing specific DoD requirements, and by improving the existing SSH and SSL design with stronger encryption keys and more secure key exchange algorithms.
• Decreased the device connection downtime caused by a network topology change from 5 minutes to 5 seconds by redesigning the software architecture by event-driven programming connecting different tasks running on the device.
• Increased the product lifetime by 5 years, by designing a custom-tailored solution to extend the lifetime of the flash memory, by designing a highly-efficient data caching solution optimizing the flash memory usage.
• Skills: C/C++, VxWorks RTOS, Tornado, Clear Case, Jira, Mantis, Clarify, IEEE 802.xx telecommunication standards, C# / .NET.

• Senior Tcl/Expect Developer at Nortel Networks / Passport Voice Gateway (PVG) (1999-2002)
• Verilog DHL Developer at Metaflow Technologies – Caesar (1997-1999)
• Visual C++ Developer at NedGraphics (1996-1997)
• Visual C++ Developer at Image Processing Lab (1996-2001)
