The client, active in the Enterprise Resource Planning (ERP) software solution market, was at high risk of losing a significant number of customers due to still using an outdated ERP software incompatible on future Windows versions and lacking important sought after features. - 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 a low-stock alarm 10 days before a piece of inventory must be ordered so that it won’t get out of stock. Skills: Backend WEB development, C# / .Net, MS SQL, Entity Framework, REST API, JavaScript, TypeScript, CI/CD, Azure: Event Grid, Event Hubs, Service Bus.

The client, the leading provider of device programming technology, was losing a significant number of their existing clients and was struggling to attract new ones due to their product lacking support for the latest IoT devices. Contributed to the increase of Data I/O's rank to the #1 provider of automated security provisioning by significantly improving the existing solution to support several of the most in-demand IoT devices, designing a highly flexible secure provisioning algorithm. Contributed to Data I/O becoming NXP's #1 security provisioning solution provider by understanding and addressing the client’s business needs, designing a “Counterfeit Device Detection” capability for the NXP SE050 device, and participating in the design of a plug-and-play dynamic user interface. Reduced NXP SE050 programming time by 20% by increasing the speed of the SE050 programming algorithm and efficiently utilizing all CPU cores using .NET Parallel Programming. Kompetenser: .NET Core · C# · .NET Framework · Azure Kubernetes Service (AKS) · WPF · Cryptography · RabbitMQ · Python (Programming Language) · JSON · Unit Testing

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 raising the priority for VRRP heartbeat packets through the protocol stack. Contributed to winning a Department of Defense (DoD) contract worth $30 million by implementing specific DoD requirements, improving the existing SSH and SSL design with stronger encryption keys, and incorporating more secure key exchange algorithms. Decreased device connection downtime caused by network topology changes from 5 minutes to 5 seconds by redesigning the software architecture using event-driven programming that connected different tasks running on the device. Increased the product lifetime by 5 years by designing a custom solution to extend the lifetime of the flash memory and implementing a highly efficient data caching mechanism to optimize flash memory usage. Skills: C/C++, VxWorks RTOS, Tornado, Wireshark, ClearCase (version control), Jira, .NET

The client, a well-known leader in the telecommunications field, was struggling to increase the profitability of their PVG product line but was failing to do so due to inefficient product testing processes. Decreased the number of employees involved in PVG testing from 20 to 4 engineers by designing a solution to automate software testing and creating a test framework implemented in the TCL-Expect scripting language. Reduced the time necessary to validate the software after each release from 7 days to almost zero working hours by automating the testing process, running the test suite overnight, and delivering results by email in the morning. Skills: Tcl/Expect, Linux

The client, an R&D laboratory within the Electronic Engineering University department, was struggling when submitting papers for publication in scientific journals due to lacking software capable of measuring the efficiency of its original algorithms in the field of image and video processing. Contributed to publishing eight original ideas as articles in leading scientific journals by designing the “Lab Image & Video Coding” software to measure and validate the performance of several original image and video coding algorithms and by developing it in Visual C++ using a document-view architecture. Skills: Visual C++, Image Filters, Wavelet Subband Decomposition, Video Processing and Encoding (MPEG-1/2/4 coding techniques, motion compensation techniques, motion estimation, motion prediction)

The client, a startup in the microelectronics industry, aimed to produce a Pentium II–compatible microprocessor but was using more resources than planned due to excessive time spent on product maintenance after each code update. Increased product validation accuracy from 80% to 100% by designing a set of tests for the Data Integer Unit and the Branch Shelf Unit and implementing them as test benches in Verilog HDL. Reduced the time required to validate the product after each code update from 5 days to under 3 hours by automating the test suite and scheduling it to run daily at a specific time. Skills: Pentium II processor architecture, real and protected mode assembly, UNIX shell scripting (bash, csh), Perl, Verilog HDL, timing analysis for Verilog modules

The client, a leading provider of Computer-Assisted Design software for the textile industry, was struggling to meet increasing customer demand for new features but was unable to do so due to a small team size. Decreased the cost-to-sales ratio from 60% to 45% for a tie manufacturer by reducing production costs—helping the designer lower the number of colors while maintaining design appeal—by designing and developing the Coloration Software as a Visual C++ desktop application. Reduced the time required to design a new model based on picture repetition from 20 days to 2 days by designing and developing the Design & Repeat Software, implementing multiple repetition patterns and parameters in Visual C++. Skills: Visual C++, MFC, Windows programming, document-view architecture, DirectX, DirectDraw, 1-D and 2-D image filtering
