What I'm looking for

I want to build full-stack products end to end—React/TypeScript + Python/.NET on AWS—owning integrations, reliability, and automation. I’m energized by cross-functional teamwork, code reviews, and mentoring while delivering real business impact.

I’m a results-driven Senior Software Developer with 7+ years of experience designing, building, and deploying full-stack web applications, system automations, and enterprise integrations. I focus on delivering complex projects end to end, from real-time IoT monitoring to ERP and payment gateway integrations.

In my most recent role, I develop and maintain full-stack web applications using a Python/Flask back end and React/TypeScript front end. I also design and implement AWS infrastructure (auto-scaling, monitoring, and container orchestration) and build third-party API connectors for payment gateways and accounting platforms.

Previously as a Senior .NET Software Developer, I led development of BI-enabled web applications using Power BI and QlikSense to support data-driven decision-making. I built internal ETL tools for efficient data ingestion into SQL Server databases and mentored junior developers on technical challenges and best practices.

Earlier in my career, I independently delivered manufacturing system automations and delivered a real-time machine result monitoring system with live production-line status updates. I’ve also built UiPath RPA bots to automate finance workflows, migrated core software modules from C# WPF to Qt/C++, and consistently enjoy collaborating with cross-functional and international teams.
