During November 2025, Janeszka developed configurable pricing tiers for the GPT-5.1 model within the hacksider/kilocode repository. She designed and implemented Flex and Priority pricing options, enabling the product to support dynamic monetization strategies and faster experimentation. Using TypeScript and backend development skills, Janeszka mapped pricing logic directly to product configuration, ensuring traceable and maintainable code. Her work addressed the absence of configurable pricing, aligning the model with Kilocode’s evolving business needs. Although the project scope was focused, the solution demonstrated depth in API development and pricing model design, resulting in improved pricing agility and potential for revenue optimization without reported bugs.
