Quality Control Lead

The very first step into the game industry, where I learned how development, art, testing, and design come together.

Dev Game Tester

I’m Radu, a passionate QA veteran with an extensive background in the Ubisoft mobile QA department. Working in games was once just a dream, and now I help game dev studios bring a smooth experience to players everywhere.

As Founder and CEO of Alkotech Labs, I believe in customizing solutions for each team. My approach blends agile methods with rigorous AAA standards, ensuring that even smaller studios benefit from proven processes. From mobile to PC, console, and VR, my focus is on collaboration, structure, and a mindset that puts quality first.

Here’s what I bring to every project:
 - Adaptability, as every team is different, solutions should be too
 - Clear structures that catch bugs early and keep projects on track
 - Reliability for consistent results at every milestone
 - An accessible approach built on years of industry experience

Over the years, I’ve helped improve testing workflows for various projects. While many details remain under NDA, what matters is consistent results: fewer crashes, happier dev teams, and better player experiences. 

My mission is to show how QA is a craft worthy of respect and constant growth.

NSF Data Science Program at CSUN

• Developed a convolutional neural network with Pytorch to classify Mars surface images.
• Tuned hyperparameters to optimize model performance metrics.
• Created a PyTorch dataset class that reads data from a CSV file and loads the corresponding image and bounding box coordinates.
• Defined data transformations to augment the training data with horizontal flips and convert PIL images to PyTorch tensors.
• Trained a Faster R-CNN object detection model pre-trained on COCO using the PyTorch library.
• Modified the Faster R-CNN model by replacing the pre-trained head with a new one that predicts classes for the specific task of crater detection.
• Split the dataset into training and testing subsets and created PyTorch dataloaders for each subset with options for batch size and number of workers.
• Constructed an optimizer (SGD) and learning rate scheduler (StepLR) for training the model over multiple epochs.

Computer Vision Intern

California State University, Northridge

• Developed an R package for use in functional regression analysis
• Determined that covariate C6 (stay at home requirements imposed by the U.S. government) had a significant effect on the number of confirmed Covid cases during the time interval of August 2020 - March 2021
• Handled preprocessing of Covid-19 time series data and used the R package to investigate the correlation between government policies and Covid-19 cases/deaths
• Conducted research on the factors contributing to the growth or decay of Covid-19 cases and deaths within the United States, using Covid-19 data from 51 states over two years.
• Proposed a novel test statistic to determine the significance of covariates over time in a concurrent functional model.
• Used bootstrapping to gain insight into the distribution of the test statistic and generate p-values.
• Created a method of variable selection based on the results of the hypothesis tests.
• Constructed and organized a United States Covid-19 dataset using R.
• Addressed data inconsistencies in the dataset, such as filling in blanks with "0" where appropriate and adjusting cumulative data format.
• Demonstrated the ability to draw conclusions about the relationship between variables that change over time.
• Built R functions to conduct hypothesis test and variable selection using functional regression models 
• Developed an R package called TimeVarConcurrentModel for analysis on data consistent with concurrent functional regression models 
• Wrote separate R documentation files for user access functions
• Successfully compiled the R package using a template provided by the CRAN website 
• Performed error checking to ensure proper upload of the R package to the CRAN website for user accessibility.
• Interpreted significance of covariates based on p-values and plotted data to visually represent significance
• Analyzed significant covariates to determine their impact on the number of confirmed Covid cases within each state
