IMPLEMENTED SOFTWARE and MASTERED TECHNOLOGY

Web2.0 Technology:

• Apps: iGoogle gadget, Facebook, Prism, GreaseMonkey and Firefox extension.
• Intranet: mainly Interim business using PHP5
  • Client planning based on YUI libraries
  • Candidates handling using , registration, availability and visit's frequency
• Internet: mainly related to UrFastR using Symfony
  • URL redirection/minification service leveraging P2P capabilities.
  • user generated content agregation
  • capcha, i18n

Peer to Peer :

• in depth study of major p2p protocols: bittorrent, gnutella
• design+dev of web4web.tv protocols: support static+live video streaming
  • low latency optimization for live streaming
  • seamless integration in webpages to leverage web2.0 trend
• Kademlia DHT implementation for transparent i18n dns replacement

Security/Cryptography :

• Found vulnerabilities in widely used routing protocols (OSPF and RIP) and opensource projects such as vtun and tinc VPN, or encrypted loop-device.
• Secure random number generator based on rfc1750
• Internet Key Exchange(IKE) daemon for IPSec
• IPSec encryption(ESP) and authentication(AH)
• Cryptographic algorithms: DES, MD5, SHA1, RSA, Diffie-Hellman
• Multi precision Modular arithmetic library using Montgomery number
• Cryptographic authentication for OSPF.
• yavipin: a secure tunnel using the state of art in network security

Low level Networking :

• major routing protocols: OSPFv2 (rfc2328), RIPv1/v2 (rfc2453)
• a mini-TCP stack (not fully compliant with rfc1122/rfc793)
• a RTP/RTCP stack for a proprietary ip phone demonstration
• some multicast stuff like IGMPv1/v2 (rfc1112,rfc2236) and being able to send/receive multicast packets.
• a SNMPv1/v2 server with rfc1213 MIBs
• better compliance to router requirements (rfc1812), ip frag/reasm

Miscellaneous (old) coding :

• Database: Efficient SQL engine bottom layer (index via btree, multi-user, shared cache, dedicated file-system)
• Compiler: Lexical parser (regular expressions/DFA), BASIC 4GL compiler
• Game: Othello using AlphaBeta, forward pruning using genetic and expert systems (ranked 6th in a worldwide contest)
• AI: Multiagent/expert/genetic system (mostly for automatic tuning)
• Image: Face extraction and recognition, OCR, FFT, MPEG/JPEG
