Production-focused engineer across backend, fullstack, mobile, DevOps, Kubernetes, Web3, exchange platforms, VPN, billing, and release readiness.
A focused portfolio for the general senior engineering profile, with one public CV and deeper project stories.
Expertise
A compact map of the areas where I can own implementation, architecture, delivery, and production quality.
Systems that hold up
Designing NestJS, Node.js, Laravel, REST, GraphQL, billing, auth, diagnostics, and data-heavy services with production contracts and clear operational ownership.
End-to-end ownership
Connecting mobile, web, backend, billing, support, admin, and release workflows so product behavior remains coherent from screen to database.
Interfaces with intent
Building fast, readable, API-driven user flows across Flutter, Angular, React, Next.js, Vue.js, subscriptions, routing, lazy loading, and Web3 experiences.
Delivery discipline
Turning code into reliable releases with GitHub, GitLab CI/CD, Docker, Kubernetes, Fleet, ingress/TLS, deployment documentation, and rollout checks.
Asset infrastructure
Working across smart contracts, custodial wallet models, cold-wallet security, private full nodes, Java-Tron, Ethereum EVM, Bitcoin Core, and Web3 product flows.
Store-facing reliability
Aligning OpenVPN profiles, subscription entitlement sync, Google Play/App Store billing, diagnostics, support tickets, app version policy, and release hardening.
Journey
Each chapter opens into a concise story page with the project context, technical stack, capabilities, outcomes, and highlights.
CV
A broad senior software engineering profile covering fullstack delivery, backend architecture, team leadership, DevOps, Kubernetes, Web3, VPN, billing, and production operations.
