Pablo Ballesteros

- Responsible end to end of the creation of the bundling algorithm, which allows the optimization of routes, significantly reducing costs and increasing revenue. - Developed and deployed and maintained the backend of several operational tools, gathering feedback from users and iterating, while collaborating on their initial design - Assisted to the control tower solution by providing detailed analytics and simulations for specific clients

- Our team became the starting point for Zalando's long term logistic strategy and assessing of challenges. Proposing, testing and advising over future strategy and algorithms - Improved upon the material flow simulation by adding more complex algorithms to represent reality, testing different ideas for item distribution. - Created guidelines and revised existing processes for making collaboration more efficient, ensuring reproducibility and scalability of analyses

- Designed a material flow simulation that includes of all the items flowing in and out the network, in which different logistic concepts and algorithmic distribution rules were tested to assess their potential impact - Took over end to end responsability of creating optimizing algorithms, data procurement and cleaning, testing and analyzing the results obtained in the aforementioned simulation - Designed and programmed a simulation to test intralogistic concepts

-Development of models and indicators to better understand the business -Developer of the Order Profit system (produces an up to 8% increase in profits during high season) -Successfully led an interdisciplinary team (8 members) to develope strategy proposals for turnover improvement (results adding up to a 2% increase in transport during high season, and a 1% reduction in costs all year round) -Analysis and control of budget deviations -Ad-hoc analyses -Calculation and analysis of KPIs

-Successfully developed and tested the Wagon Tracking System (eliminated duplicated data input and provides better information to improve KPIs reliability and to measure previously unmeasurable processes) -Tasks automatization (produced actionable information faster and more reliably, reduced or eliminated routinary jobs) -Ad-hoc Project feasibility analyses -Development, calculation and analysis of KPIs for different areas, mainly traffic and maintenance

-Developer and programmer of the Loading Efficiency System (achieved an income increase of 1.5% and a cost reduction of 3.5% with no investment) -Creator, developer and programmer of the Wagon Turnover Rate indicator (main KPI used from this point on in all feasibility and impact analyses) -Development of simulation tools using the ExtendSim package (successfully used to perform project impact analyses). -Design and programming of a Geographic information system (GIS) tool -Transit time speed analyses

-Supervision of security courses -Categorization of projects
