Rationalization of legacy environments :- Applying minimal effort in reverse engineering undocumented older software and porting it to modern OSes, while keeping functional compatibility and avoiding degradation of functionality, to secure the required timeframe for more complete migration solutions- Re-implementing legacy solutions (in production since the 90ies) using open source tools, improving them in the process and contributing to the open source community (including FreeRADIUS… Show more Rationalization of legacy environments :- Applying minimal effort in reverse engineering undocumented older software and porting it to modern OSes, while keeping functional compatibility and avoiding degradation of functionality, to secure the required timeframe for more complete migration solutions- Re-implementing legacy solutions (in production since the 90ies) using open source tools, improving them in the process and contributing to the open source community (including FreeRADIUS Apache module, Nagios, FreeBSD/pfSense, Unbound)- Re-designing such systems so that they follow the most modern security and networking architecture practices (Separating frontend and backend to ensure SSL encryption stack is up-to-date)Process improvement, optimization of both network & server environments :- Infrastructure as Code using Ansible- Migration of legacy applications to an isolated environment using VMware Horizon- ActiveDirectory domain re-design for network segregation (RODC) and for multiple sites- Management of in-house PKI (SSL CA, end-to-end encryption)- Rationalized existing legacy services using HAproxy- Mitigated DNS-based DDoS threats by contributing to the Unbound DNS server project by implementing AAAA filtering, and a realtime attack interception systemMonitoring/automated processes :- Implemented processes to detect attack signs (massive unauthorized use of credentials, from multiple sources, massive traffic), and escalate alerts to more advanced detection/handling processes- Implemented automated response systems for edge filtering of massive DDoS attacks to ensure network integrityInternational projects with foreign companies :- Support to upper management as a translator (English <-> Japanese), for both written and oral communication during business trips, and ensuring permanent smooth communication to assist project managementStrategic Research & Development :- Participated in designing several solutions and acquiring patents Show less
