About

Full-Stack Software Engineer with 4+ years of experience building scalable backend systems, real-time applications, and cloud-native platforms across fintech, social commerce, marketplace, and SaaS products. I specialize in designing modular microservice architectures, serverless platforms, and high-throughput APIs that directly impact product growth and user engagement. My work has spanned social authentication systems serving thousands of users, video interaction pipelines that cut API load by 60%, legacy-to-modern architecture migrations that reduced feature delivery cycles from weeks to days, and cross-platform mobile apps shipped to both the App Store and Google Play. My core stack is TypeScript, NestJS, GraphQL, React, and AWS, but I work comfortably across the full spectrum, from Python and FastAPI, to Rust for systems programming, to Java and Spring Boot for enterprise microservices. What I bring to teams: • Deep backend expertise: API design, database modeling, caching strategies, queue-based processing, and real-time systems • Full-stack ownership: I ship end-to-end backend services, web frontends, mobile apps, and infrastructure • Cloud-native fluency: AWS Lambda, CDK, EKS, Docker, CI/CD pipelines, and Kubernetes • Startup velocity: I thrive in fast-paced environments where I own features from design through deployment I'm always looking to connect with engineers, founders, and teams building ambitious products. Let's talk.
