RishvinPortfolio
I deliver end-to-end solutions across IoT, Blockchain, Cyber Security and Full-Stack Engineering — from prototyping hardware to shipping secure, production-ready software.
Hardware prototyping (Arduino/ESP), sensor integration, firmware and edge-to-cloud communication (MQTT).
Smart contract prototypes, transaction flows, and proofs-of-concept for secure, auditable interactions.
Threat-aware architecture, encryption (AES/SHA), TOTP, hybrid biometric + OTP solutions and secure key handling.
APIs (Flask), web frontends, realtime features, and database-backed services for reliable product delivery.
Designing scalable architectures, CI/CD ideas and deployment-ready handoffs with monitoring and logging in mind.
Rapid breadboard prototypes, Proteus simulation, PCB iteration guidance and integration testing.
Model prototyping, OpenCV-based vision modules and basic TensorFlow workflows for embedded/edge inference.
UI/UX design, prototyping, usability testing, documentation and peer mentoring for student teams and junior engineers.
