# Uday Kiran Dasari > Software Engineer | Building AI Systems, Data Pipelines & Full-Stack Applications | LangGraph, Spark, Python, FastAPI, AWS, Next.js Location: San Jose, California, United States Profile: https://flows.cv/udaykirandasari Software engineer with 3+YOE. I build AI applications, data pipelines, and full-stack systems. Building AI applications end-to-end means owning every layer. I've built the data pipelines that feed them (Airflow, dbt, Spark, Kafka, Snowflake), the backend services that power them (FastAPI, LangGraph agents, RAG pipelines, vector databases), the frontends that surface them (Next.js, React), and deployed them on AWS and GCP. Currently doing this solo for a real-time voice AI product: STT/LLM/TTS pipeline with sub-second latency, WebRTC streaming, PostgreSQL, serverless deployment. I also work at the model level. Fine-tuned LLMs and Stable Diffusion with LoRA, built CNN-LSTM networks for time-series prediction, and implemented transformer architectures from scratch. 3+ years building production software. Previously shipped FastAPI services and Spark/Kafka pipelines for enterprise supply chain software serving 50,000+ suppliers. MS in Computer Science, Northeastern University (May 2025). Tech: Python, FastAPI, Spark, Kafka, Airflow, Snowflake, PostgreSQL, Redis, AWS, Docker, LangGraph, Next.js Open to Software Engineering, AI/ML Engineering, and Data Engineering roles.
