What I'm looking for

I'm looking to build scalable backend systems and developer-focused SaaS products in lean, agile teams where collaboration and ownership drive product success. I also want to grow through open-source contribution, AI agents, and frontend development.

I've built production backend systems for AGAM Technologies, Fluvi.com, and Onwords Automation, working across fintech, Amazon seller SaaS, IoT, and internal business tools.

At AGAM Technologies, I developed and maintained Python microservices for client-facing fintech projects, integrating Leegality, IDfy, and CCAvenue while iterating quickly on scalable, reliable features.

At Fluvi.com, I contributed core FastAPI backend code for a SaaS platform used by Amazon sellers. I handled sales, orders, and performance-metric ingestion and aggregation, while maintaining Amazon API integrations around rate limits, authentication flows, and data consistency.

As the founding backend developer at Onwords Automation, I delivered full-stack applications end to end, including the company website, an IoT home server, CRM, and dashboards. I'm continuing to explore AI agents and SaaS while expanding into React and Next.js, with a long-term goal of building useful developer-focused tools and contributing to open source.
