About Me
I specialize in backend development and anti fraud solutions for online platforms and fintech.
I build and maintain high load services: design APIs and integrations, set up queues/workers, monitoring and alerting, and automate processes.
My main stack is Python and Node.js; I also work with other languages as needed e.g., Go/Java/TypeScript. Please confirm additional languages in advance.
I develop parsers and data collection pipelines: HTML/JSON processing, proxy and retry handling, data normalization, job schedulers, etc.
I’m confident working with databases: schema design, query and index optimization, transactions, migrations; I use SQL PostgreSQL/MySQL and NoSQL e.g., Redis/MongoDB depending on requirements.
In anti fraud, I build event pipelines and scoring systems: rules, limits, risk segmentation, analysis of IP/geo/device/behavior signals.
