# Mehedi Shohag > Senior Software Engineer @Capital One Location: New York City Metropolitan Area, United States Profile: https://flows.cv/mehedi I am a Senior Software Engineer with 6 years of experience designing and scaling distributed systems, event-driven architectures, and backend platforms at scale. My expertise spans high-throughput APIs, microservices on AWS, and AI/LLM-powered applications, with a strong track record of delivering measurable business value. At Capital One (NYSE: COF), I designed and deployed an enterprise-grade LLM-powered chatbot by fine-tuning LLaMA with internal data and orchestrating workflows using MCP + AWS (Bedrock, Lambda, Step Functions, EventBridge, DynamoDB). This reduced developer resolution time by 40% and improved productivity by 30%. I also led REST and GraphQL API development that drove $5ā€“7M in business value, deployed distributed microservices on AWS Fargate with 20% cost savings, and analyzed 400M+ data points with Spark/EMR for performance validation. Previously, at Accenture (NYSE: ACN), I migrated legacy systems into event-driven microservices, built Kafka/RabbitMQ pipelines, and implemented serverless AWS Lambda workflows that improved scalability and reduced downtime. I thrive at the intersection of backend engineering, distributed systems, and AI, and Iā€™m passionate about building platforms that scale globally, improve developer productivity, and accelerate innovation. šŸ”¹ Core Expertise: Distributed Systems | Event-Driven Architecture | Microservices at Scale | High-Throughput APIs | Cloud-Native Platforms (AWS) | LLM/AI Integration šŸ”¹ Tech Stack: Java, Python, Spring Boot, Kafka, RabbitMQ, gRPC, REST, GraphQL, Cassandra, PostgreSQL, DynamoDB, AWS (Fargate, Bedrock, Lambda, EMR, Step Functions, EventBridge) ## Work Experience ### Senior Software Engineer @ Capital One Jan 2023 ā€“ Present | New York City Metropolitan Area -
