WORK HISTORY
Full-stack Developer @Pinterest
ON, CA
Designed and developed scalable full-stack applications using Python (Flask/FastAPI) and modern frontend frameworks, delivering high-performance, secure RESTful APIs and seamless user experiences.Architected and implemented microservices-based backend systems, supporting high-concurrency, real-time, and distributed workloads across data-driven platforms.Built and optimized data processing pipelines using Pandas, NumPy, and distributed frameworks (Dask), enabling efficient handling of large-scale structured and unstructured datasets.Developed and integrated AI/ML and Generative AI (GenAI) solutions, including LLM-powered workflows, NLP pipelines, and Retrieval-Augmented Generation (RAG) systems using LangChain, OpenAI, and vector databases for intelligent automation and semantic search.Integrated machine learning models into backend services for real-time inference, predictive analytics, and data-driven decision support.Implemented workflow orchestration and scheduling using Apache Airflow, automating ETL pipelines and improving operational efficiency.Built event-driven and asynchronous systems to support scalable, low-latency data processing and background job execution.Strengthened system scalability and reliability by leveraging AWS cloud services (S3, Lambda, EC2), containerization (Docker), and modern deployment practices.Designed and maintained CI/CD pipelines (GitHub Actions/Jenkins), enabling automated testing, faster releases, and consistent deployments.Improved application performance through caching strategies, database optimization, and query tuning, ensuring high availability and low latency.Implemented monitoring and observability solutions (CloudWatch, logging, metrics), enabling proactive issue detection and performance optimization.Collaborated with cross-functional teams in Agile environments, contributing to system design, code reviews, and delivery of high-quality, production-ready features.
ABOUT MANSI C
Senior Full Stack Developer with 7+ years of experience building scalable, high-performance backend systems and data-driven platforms across fintech, healthcare, logistics, retail, and SaaS domains.I specialize in designing robust microservices and APIs using Python (Django, FastAPI, Flask) and modern architectures that support high-concurrency, real-time, and distributed systems. My work spans end-to-end product development—from backend engineering and data pipelines to cloud-native deployments and performance optimization.With strong expertise in ETL pipelines, event-driven systems (Kafka, Kinesis), and distributed data processing, I’ve built solutions that efficiently handle large-scale structured and unstructured data. I also have hands-on experience in AI/ML and Generative AI (GenAI), building LLM-powered applications, NLP pipelines, and Retrieval-Augmented Generation (RAG) systems using LangChain, OpenAI, and vector databases for intelligent automation, semantic search, and advanced analytics.I bring deep experience across AWS, Azure, and GCP, implementing CI/CD pipelines, containerization (Docker, Kubernetes), and Infrastructure as Code (Terraform, CloudFormation) to deliver secure, scalable, and highly available systems.Having worked with organizations like RenaissanceRe, Live Nation, Agfa Healthcare, Kroger, and Ellipsis Infotech, I thrive in Agile environments, collaborating with cross-functional teams to deliver impactful, production-ready solutions.I’m passionate about solving complex engineering challenges, optimizing system performance, and continuously exploring emerging technologies, including LLMs, NLP, and AI/ML systems, to build smarter, more efficient platforms.
