At Kokoc Group, I delivered a ChatGPT-API-based resume-screening pipeline, from system prompt engineering and candidate-scoring algorithms to HR ecosystem integration. It cut processing time from hours to minutes.
I also took a Big Data and ML-integrated Telegram bot from MVP to production, engineering API integrations and conversational logic to test hyper-personalization hypotheses. Across five projects, I managed budgets, SLAs, roadmaps, backlogs, and teams of up to 12.
At AR Bureau, I coordinated systems integration, API development, and data pipelines across B2B platforms and mobile apps. For Flame at Kokoc Group, I designed and launched a payment platform from scratch, including B2C checkout and card integration; the work reduced payment errors and transaction drop-offs by 35%.
