Recommended and implemented Cloudflare-first architecture for resilient, secure, and scalable microservices, including DNS, CDN, Workers, and edge routing. Architected hosting and API proxy strategy using Cloudflare Workers to serve web apps and proxy REST APIs for reduced latency and improved security. Built Next.js landing page for ShikaWallet.com and developed MVP mobile app in React Native (core flows, auth, API integration). Led domain configuration and DNS strategy to ensure high availability and DDoS mitigation across services. Designed and implemented scalable voting system using Go, zk proofs (gnark), and ZK-SNARKs for privacy-preserving verification. Implemented REST API proxy with Hono.js on Cloudflare Workers (Swagger-documented) to forward requests to the main node sequencer and enforce access controls. Containerized services and automated deployments with GitHub Actions, Docker, and Ansible for repeatable CI/CD and infrastructure provisioning. Instrumented logging, monitoring, and alerting to track uptime, voting events, and deployment health, improving incident response and platform reliability.

Built and launched a production digital business‑card service end‑to‑end using Native Android, Node.js and PostgreSQL. Designed and implemented REST APIs and backend services for user accounts, sharing, analytics, and synchronization (Node.js). Modeled PostgreSQL schemas and added indexes to support efficient queries and analytics workloads. Delivered a native Android app with offline support and reliable sync, improving UX in low‑connectivity conditions. Owned product, development and operations solo: roadmap, feature prioritization, deployments, monitoring and user support. Ran a private beta, acquired initial users organically, and iterated product from direct user feedback. Project discontinued after failing to reach sustainable growth; lessons learned refocused career toward engineering, scalable architecture, and product execution.
