At a Chilean startup, Mr. Astudillo is defining the architecture and technologies to extend an existing CRM product into a product line with web-, WAP- and B2B capabilities.
Graduate Research, Teaching and Advising (8/1998-6/2000).
As a Professor-Doutor at the Computer Science Department, University of São Paulo, São Paulo, Brazil, Mr. Astudillo performed research (focused in software architecture, object systems and requirements engineering) with graduate students. He also taught graduate classes in these areas. He is still thesis advisor (2000) of some M.S. students.
SIDAM (Sistema de Informação Distribuido para Agentes Móveis) (5/1998-3/2000).
At the Computer Science Department, University of São Paulo, São Paulo, Brazil, Mr. Astudillo was part of the SIDAM team, and helped define the architecture for a testbed system to allow deployment and experimenting of alternative protocols, policies and configurations for large mobile distributed systems.
Info.Cultura (9/1998-9/1999).
At the Computer Science Department, University of São Paulo, São Paulo, Brazil, Mr. Astudillo was part of the Info.Cultura team, an inter-disciplinary group drawn jointly from the computer science and journalism schools. He lead the development of a prototype of a web-based registry of heritage places and agrupations across Brazil.
Architecture methodology for distributed object systems (6/1998-8/1998).
At the MCI Systemhouse Object Global Practice, Mr. Astudillo co-authored a methodology and templates for definition and delivery distributed object systems. His contribution focused on thearchitecture definition task, and on the architect's role in a project. The effort outcomes include an architect's primer and some innovative notations, to be presented at industry workshops and conferences in short term.
High-availability distributed payments system (5/1998-8/1998)
At a large U.S. bank on behalf of MCI Systemhouse, Mr. Astudillo was the lead architect in the design of the U.S. Treasury Cash-Link, which aimed to automate payments by commercial banks to U.S. federal agencies. The project addressed the need to decentralize payment processing to the proper Fed branch, and of immediate reporting for positioning and forecasting. The project outcomes include a distribution architecture, consisting of a high-availability payments mediator (OLTP-like, distributed, replicated and load-balancing), and a high-capacity historical analysis center (centralized and fault-tolerant).
Reinsurance risk evaluation system (12/1997-5/1998)
At the largest U.S. reinsurance company on behalf of MCI Systemhouse, Mr. Astudillo was the lead architect in the Knowledge Based System project, which aimed to facilitate delivery of reinsurance expert medical knowledge to third-party underwriter desktops. The project addressed two bottlenecks: reuse of medical knowledge across multiple products (each with a manual, wizards and workflow description), and delivery of multiple products in a common "underwriter workstation". The project outcomes included a prototype and a long-term architecture, consisting of a collaborative medical modeling and publishing tool, and a common workstation with product-specific workflow models.
Sales commissions system (2/1997-3/1998)
At a large long-distance phone company on behalf of MCI Systemhouse, Mr. Astudillo was chief architect in the Project X. The system facilitates the payment of sales commissions to the client's sales force, satisfying three key stakeholders: marketing (writing compensation plans), HQ personnel (maintaining a sales assignments model), and payroll (producing periodic statements using the plans and assignments to process ~1TB of revenue data feeds).
His project-related outcomes included: (as chief architect) exercised general technical oversight and assessed technical risk; (as application architect) identified key technical issues, defined the application architecture, and coordinated development work allocation; and (as object architect) designed and built the key subsystem to describe compensation plans, which included an ad-hoc language ("BOMscript") and associated tools (compiler and meta-modeler).
MCI Systemhouse methodological efforts (9/1997 on)
Mr. Astudillo participated actively in an internal Object-Oriented Methodology Task Force, formed to define an object-oriented methodology for object-oriented projects. The results remain internal to the company.
Large health insurer claims processing (8/1997)
Mr. Astudillo participated in the initial design for a Blue Cross/Blue Shield, aiming to migrate its mainframe-based COBOL systems into an O-O client-server system. Project outcomes included a long-term system architecture and a migration path. The proposed system included a mainframe-sized scale workflow engine, preserving the client’s investment in existing core systems yet re-deploying auxiliary functions in an object-oriented client-server model.
Applied research with the CMU's Software Engineering Institute (7/1997-12/1997)
Mr. Astudillo participated in an R&D initiative aimed to define a single Architecture Handbook and Architect Starter Kits, for company-wide use by application architects in future projects. The initiative included collaboration with the CMU’s SEI.
Large bank Profitability Reporting Facility (2/1997)
Mr. Astudillo performed an architectural review and detailed subsystems design (particularly Security) for a PRF. Involved technologies included DCE in a 3-layers O-O system.
UML definition and OMG submission (9/1996-1/1997)
Mr. Astudillo was part of MCI Systemhouse's team that helped to define the UML (Unified Modeling Language) and its subsequent submission to the OMG as standard for Object CASE modeling. The project team suggested notation changes and additions to accommodate the modeling of distributed and fault-tolerant systems, particularly of CORBA flavor. See resulting publications below, including some white papers are available at the OMG web site.
OO CASE tool evaluation (6/1996-8/1996)
Mr. Astudillo participated in substantial evaluation of OO CASE tools for adoption as Systemhouse's corporate standard, which involved test-driving several such tools. He also collaborated with an interactive, multi-media Tutorial on Object-Oriented Design for online publication.
Programming Languages instruction (‘94-’95 academic year)
As an instructor at the Georgia Institute of Technology, Mr. Astudillo has given a quarterly college Survey of Programming Languages (CS 3410) course, with full responsibility for contents, preparation and evaluation.
UI cognitive design tool (Summer ’93)
As a Project Assistant at the Georgia Institute of Technology, Mr. Astudillo built key pieces of a multi-person, multi-year User-Interface Design Environment to evaluate efficacy of cognitive models to support UI design. He built a central source code repository, and ported (actually, extended) the client-server interface from library-based code on Sun’s OpenWindows clients to process-based code in Siemens’ SX/Tools clients.
Workflow coordination tool (Spring ’93)
As a Project Assistant at the Georgia Institute of Technology, Mr. Astudillo prototyped the Knowledge Worker Platform Analysis, as proof of feasibility for Unix/XView porting of an existing MS-Windows coordination tool. The client agreed to finance the whole port based on this prototype.
Model derivation automation (1991 to 1993)
As a Graduate Research Assistant for a (semi-) automated support system for metrics-based derivation of strongly typed software systems from object-based domain models, Mr. Astudillo researched and built a Smalltalk testbed to propose and evaluate derivation criteria and rules, and combined with NeOpus (an object-oriented rule system).
NCR Cooperative Computing Systems Division (Summer ‘91) -
As an Intern, Mr. Astudillo ported the Security Framework (a subsystem of "NCR Cooperation" inter-platform distributed objects environment) to a Unix platform, documented it from scratch and built additional applications.
Graphical editor (‘89-90 year)
As a Graduate Project Assistant for the "Spock" project, Mr. Astudillo built part of, and later extended, an X-based graphical editor for multiprocessor software ("BDE"). He also prepared the specification and overall design for GEI, the successor of BDE.
Object-oriented storage system (‘89-’90 year)
As a Graduate Research Assistant on object-oriented databases and schema evolution, Mr. Astudillo built a prototype C++ object-oriented storage system on top of the (then experimental) Wisconsin Storage System (WiSS).
Distributed databases queuing simulation (‘89-’90 year)
As a Graduate Research Assistant on performance evaluation, Mr. Astudillo built a queuing network discrete-event simulation model of a distributed database. He implemented it on IBM CMS using the RESQ2 language. He also developed and published "Q", a queuing simulation language.
MIS instructor (’87 year)
As an Instructor at the Dr. Jaime Michelow Computer Science School, Mr. Astudillo conducted a yearlong course of Management Information Systems to a college 4th-year class. He developed the lecture plan and supervised students in practical training projects.
Programming instructor (’87 year)
As an Instructor at the Universidad Técnica Federico Santa María, Mr. Astudillo taught (two semesters) a course of Computer Programming (using Pascal) to college freshmen. He also participated in the draft of a textbook for this course.
Overtime analyst (Summer ’87)
As an Intern at the National Mining Company, ENAMI, Mr. Astudillo analyzed the severe chronic overtime in a Minerals Purchase Agency, and found that the recently adopted computerized system was indeed the root of the problem, generating additional reporting work. He proposed an integrated solution.
