I specialize in solving networking problems that traditional software developers rarely encounter. Modern infrastructure is no longer just about writing code or configuring servers; t's about understanding how applications, operating systems, protocols and networks interact. That's where I work. I design, build and troubleshoot secure, high-performance infrastructures where backend engineering, Linux administration and advanced networking come together. Whether the challenge involves VPN deployments, routing, DNS, TLS, packet analysis, distributed systems or backend services, I enjoy finding the root cause and building solutions that are reliable, maintainable and practical. My strongest expertise is modern Internet infrastructure. I regularly work with Linux, OpenWrt, WireGuard, Sing-box, Xray-core, secure tunneling, advanced proxy architectures, Deep Packet Inspection (DPI), traffic analysis, routing, NAT, policy-based routing, reverse proxies, DNS, TLS, HTTP/2, HTTP/3, QUIC and Wireshark. I also have experience building censorship-resistant networking solutions and understanding how modern protocols behave in restrictive or complex network environments. Beyond networking, I develop backend services, APIs and automation tools using Node.js, Express, JavaScript and SQL technologies including PostgreSQL, MySQL, SQLite and MongoDB. I'm comfortable reading, understanding, debugging and improving existing codebases, integrating new features, optimizing performance and helping maintain production systems. I enjoy projects that require looking at the complete picture rather than a single technology. Whether the issue originates from application code, a database query, TLS negotiation, DNS resolution, container networking, routing or packet-level behavior, I investigate the entire stack until the root cause is identified. My approach -> understand the problem, communicate clearly, build solutions that last, and leave clients with infrastructure they can confidently operate after the project is complete. If your project involves networking, Linux infrastructure, VPN technologies, backend development, protocol analysis, traffic engineering, performance optimization or complex troubleshooting, I'd be happy to help.
