About
Engineer, product builder, and practical platform thinker.
I am a senior full-stack software engineer at esurance.ch and a master's student in Business and Finance Management at Jagiellonian University, combining hands-on engineering delivery with a strong business and product background.
I work best where software has real operational weight: roles, permissions, approvals, payments, calculations, localization, reporting, integrations, admin workflows, and long-lived product decisions.
My background combines business administration, finance and management, software engineering, and product delivery. That helps me translate business problems into systems that are practical for users, maintainable for developers, and understandable for stakeholders.
I have worked across insurance, automotive, e-commerce, job-search, enterprise tools, marketplaces, and mobile products. The common thread is ownership: understand the domain, design the flow, build the system, test the edge cases, and keep improving after release.
I care about software that feels clear and reliable to use. Strong visual judgment, adaptability, time management, and practical problem-solving are part of how I deliver robust applications without losing sight of business value.
How I Work
I turn unclear product problems into architecture, data models, UI flows, API contracts, tests, release plans, and measurable improvements.
Team Context
Comfortable working with product owners, Scrum teams, designers, QA, backend/frontend engineers, founders, and business stakeholders across remote international teams.
Systems Mindset
I think in workflows, constraints, API contracts, data models, permissions, localization, release risks, cloud patterns, and user-facing reliability.
Product Delivery
Built and led delivery for automotive, e-commerce, enterprise safety, mobile, job-search, and internal dashboard products with a focus on production quality.
Business & Research
Master's student in Business and Finance Management at Jagiellonian University, with academic interests in AI-driven platforms, business model transformation, and platform markets.
International Collaboration
Experienced with Swiss, U.S., Polish, Azerbaijani, and international teams, including stakeholder alignment, technical communication, QA coordination, and delivery planning.
Experience
Senior delivery across enterprise, automotive, insurance, and mobile platforms.
A concise view of the work history behind the portfolio, with emphasis on ownership, architecture, performance, localization, QA, and production delivery.
