scalable systems.
I am Swayanshu — crafting high-performance mobile applications and distributed backend architectures engineered for reliability, fluid UX, and speed.
01 // About Me
Driven by logic. Designed for scale.
I am Swayanshu Sarthak Sadangi — a Software Engineer specializing in cross-platform mobile engineering and high-throughput backend infrastructure. With expertise spanning Flutter, Spring Boot, PostgreSQL, and Cloud Architectures, I design systems engineered for speed, low-latency responsiveness, and fault-tolerant reliability.
My engineering approach prioritizes Clean Architecture, modular system design, and rigorous performance optimization. From building distributed RESTful services and event-driven microservices to delivering fluid, native-tier mobile user experiences, I bridge technical complexity with intuitive product design.
Demonstrated by 15+ live applications, competitive hackathon achievements (Top 10 at HackNITR 7.0), and an academic record of 9.06 CGPA, I thrive in fast-paced collaborative environments. I continuously refine system scalability, automated CI/CD pipelines, and cloud-native practices to craft software that elevates user experiences.
