I'm an independant and freelance consultant. I provide training and consulting services to leading spanish and multinational companies such as KPMG, Bank of Zaragoza, Bank of Santander, Banesto, Atos Origin,Jazztel, Madrid City Council, Bank of Spain, Ministry of Defense and others. Topics of expertise include Java/Web technologies, Mobile platforms, Web 2.0 applications, Service Oriented Architectures and Cloud Computing.
I'm also an avid software deveoper and experimenter. You can see some of my recent "for-fun" developments in my software projects page.
Member of the Scientific Advisory Committee of the Archimedes Project - a joint project by the Education and Science Department and the University of Murcia and the CNICE (Ministry of Science and Education) for the development of an educational TV series aimed at divulging science among kids. I was also charged with the specification and design of the Internet part of that project
Design and development of a system for injecting internationalized messages into existing web applications. The system featured request interception and on-the fly translation of the generated output.
Design and development of a transparent profiler for measuring web application performance and detecting bottlenecks.
Design and development of a java charting and graphing library.
As a Project Manager at PSD, I designed and led the team that implemented the following commercial products
Kryptos – A cryptographic toolkit and library for Delphi/VB. Featured implementations of some of the most important protocols at the time : DES, 3DES, Twofish, Blowfish, stream ciphers with long-period PRNGs, and more. The system was used by customers such as the Russian Embassy in Madrid or Texaco Brasil
SourceGuard – A version control system with bug tracking, source compliance metrics, code inspection support, visual differencing, etc.
Winproblem – A system for defect/incident tracking and reporting, geared towards ISO 9000 requirements and procedures.
Evolve – A patch creation/distribution system for Windows-based systems.
Under my direction PSD started and implemented a process for software quality assurance as dictated by ISO 9001 and ISO 9000-3
An IVR (Interactive Voice Response) system for Dialogic boards and Windows 3.1 for telephone access to database data. The system included TTS (Text-To-Speech) synthesis, DTMF based queries and options like fax-back and voice mail.
Many different applications for Lotus Notes 4.5 - Purchase management, Code Reviews, Quality Audits, etc.
Design and Implementation of a turnkey real-estate valuation and appraisal system of the Bank of Santander. As a team lead, I oversaw the substitution of the existing (non-working) system with a completely rewritten one. The project was delivered on time and within the planned cost, resulting in net savings of over 10 million pesetas per year. When I left the project, it was handling all mortgage-related appraisals of the bank (over 500/day), and was accumulating a real-estata database of more than a million items.

As an experimental project, a multimedia communications terminal software ("Terminaltor II"), winner of the CATACOM'93 software contest, sponsored by Borland, Quarterdeck and Microsoft, in the area "Best communications software". The software (running under MS-DOS), besides the traditional features of the time (xModem/zModem transfers, ANSI terminal emulation, etc) featured a proprietary protocol that allowed the BBSs to present the user a GUI interface and interactive graphics.
Also, as an experimental project, a mathematical graphing program for exploring partial differential equations and systems of PDEs, as part of the "Mathematical method of physics"course of the Complutense University.
System for control and appraisal of plots of land and real estate properties for Merca/3 S.A. The system was later used by the land registries of many city halls.
As a personal project, a multimedia hypertext system, winner of the CATACOM'92 contest in the "Best MS-DOS utility" category. The system was later used for one of the first electronic magazines - MicroPress
