Challenge
Privacy-oriented DNS resolvers often lose either performance or security hardening. OxyDNS was built for environments where anonymity, validation, and operational resilience matter more than a minimal toy setup.

Systems & Infrastructure
OxyDNS
High-performance, secure DNS server with advanced blocklisting and caching. Features DoT (DNS over TLS) support, DNSSEC validation, and Tor integration.

Build approach
I combined recursive resolver work with DNSSEC validation, optional Tor routing, sharded caching, QNAME minimization, 0x20 encoding, and built-in blocklisting to produce a resolver that treats security and privacy as core architecture decisions.
Outcome
OxyDNS strengthens the cybersecurity and infrastructure side of the portfolio. It shows protocol-level engineering with concrete privacy and hardening decisions rather than generic security claims.
Additional Information
A production-ready DNS resolver with built-in blocklist support (100k+ domains), LRU caching, and cryptographic verification. Supports multiple upstreams with parallel race mode for ultra-low latency.
