Application Developer rinf.tech
I own the end-to-end delivery lifecycle for assigned customer applications, acting as the primary technical point of contact. I gather requirements, convert partially defined business needs into technical scope, implement integrations with customer systems, deploy solutions to production, and provide post-launch support.
I built a server-side integration between an Android application and a Frappe Python web platform, enabling bidirectional operational data exchange between field devices and a central company system. I also migrated a rail-operations analytics application from manually uploaded CSV and Excel files to live SQL Server data, creating SQL aggregation logic and validating data quality.
I work in existing production codebases with incomplete documentation, tracing system dependencies and data flows before implementing changes. I also developed an Android application for safety-critical medical transport that processes live multi-sensor data, monitors conditions in real time, and generates driver-facing status information and alarms.
