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.
