## Headline

Software Development Engineer @ Yutitech Innovations Pvt Ltd \| Prompt Engineering, Fine Tuning

## About

I am a Software Development Engineer with a strong foundation in building scalable, secure, and production\-grade backend systems using Python, FastAPI, PostgreSQL, Docker, Redis, and AWS\. Over time, my work has increasingly moved toward the intersection of backend engineering and applied AI \-building LLM\-powered workflows, RAG pipelines, prompt\-driven features, and intelligent automation systems that solve real business problems\. This is the space I find most compelling to build in\. I contribute to systems where backend infrastructure and AI capabilities work together \- from REST APIs and database design to retrieval architectures, structured model outputs, and end\-to\-end automation pipelines\. I'm deeply interested in AI engineering, backend architecture, and distributed systems\. I enjoy thinking in terms of pipelines and system design, writing clean and maintainable code, and building software that is reliable, scalable, and genuinely useful in production\.
