    Speechify
    Mar 2024 - Current (2 years 6 months)
    Engineering leadership for Speechify's consumer platform and AI infrastructure. 50M+ users, millions of daily requests. Rearchitected a fragile, duct-taped inference stack into a production-grade serving platform - cut latency by 20-30%, reduced serving costs by ~40%, introduced proper capacity planning, and eliminated constant outages. Grew what started as a 2-person payments squad into the company's platform team - now owns the entire backend: auth, subscriptions, library, content pipelines, inference, and every API the product teams ship on top of. Designed and launched Speechify's TTS API platform. Took a siloed team and restructured it around shared goals and clearer ownership. Replaced third-party churn tooling with in-house ML mode

    SQL Scrolls - A Reusable and Extensible DGBL Experiment
    CSERC The th Computer Science Education Research Conference Nov
    The teaching of databases and SQL is an active research area. We contribute by presenting a reusable and extensible SQL teaching experiment which uses a game and fits the paradigm of digital game based learning (DGBL). Although DGBL is hampered partly by the difficulty of obtaining statistically significant empirical results, the research shows that it may be an effective learning method and that it is in demand. We investigate the acceptance and effectiveness of an SQL learning game and focus on two areas: student reaction to games as a vehicle for teaching, and educational effectiveness. We designed a game prototype and administered a pre test, post test and an acceptance survey, with seven part-time and sixteen full-time students. A stat

    A Comparison of Nearest Distance Optimization and Ant Colony Optimization for Order Picking in a Multi-Aisle Warehouse
    ISMSI th International Conference on Intelligent Systems Metaheuristics Swarm Intelligence Apr
    Today, warehouses and the IT infrastructure behind them ensure smooth processing of customer orders throughout the day in all supply chains. These orders can consist of one item up to hundreds of items. The size and heterogeneity of warehouses also impedes the fastest possible processing of all orders. This research compares the nearest distance optimization heuristic and ant colony optimization to find out whether one or the other route leads to faster picking times in several scenarios depending on the warehouse size or the number of items on the picking list. For this purpose, we chose the widespread multi-aisle layout of a warehouse for our study assuming that only one human worker is involved in picking the items on the list.
