Projects
ArchDNS.com
A personal project to create a highly available, free-of-charge managed DNS service. I single-handedly developed a user-friendly control panel using PHP, Python, and C to interface with a PowerDNS backend. The entire platform was supported by a distributed, multi-node, fault-tolerant network that I designed and built to ensure immediate failover without using anycast, providing robust and secure DNS zone management for both my own domains and external users.
Bit LC Inc.
As one of the founders of Bit LC Inc., I was at the forefront of the emerging cryptocurrency landscape. During a pivotal time for Bitcoin's growth, we provided a suite of essential services, navigating the complex challenges of security, scalability, and adoption for an early user base. This pioneering venture provided deep, firsthand experience in the volatility and immense potential of the early digital currency market, ending abruptly in early 2013 due to a major security incident common in that unregulated era.
I have other projects as well, but the ones above are the most prominent projects from the past.
