Who I Am and Where I've Been

I am a senior software engineer with a track record of delivering robust

systems on time, on budget, and on scope.

I have broad experience: I've built web apps, web services, financial

software, TCP/IP servers, and VoIP phone systems. In a past life I was a Unix

sysadmin. I've written products in OO Perl, Java, and C++. I've used SQL

databases extensively (both DML and DDL). Lately I've specialized in web apps

and web services. I learn new technologies quickly, independently, and off

the clock.

I've succeeded in start-up, university, and corporate settings, on teams,

solo, and as team lead. I've seen numerous projects through the entire

product life cycle. I enjoy partnering with my customers, bridging the

gap between technical details and business results. I pride myself on keeping

stakeholders informed and happy, and delivering on schedule.

What I Can Do for You

I do contract work for large and small clients.

- I can build you an office phone system from scratch, using VoIP,

for significant cost savings over a PBX solution.

- I can build you an IVR (phone menu system): "press 1 for sales, 2

for support I can integrate with your database to create

sophisticated commerce, support, and CRM phone apps.

- I can build you a dynamic web site. I do the system administration,

back-end code, and Javascript, and I bring in design talent to do

the content (XHTML and CSS). I manage my own design talent, acting

as master contractor.

- I can enhance your existing systems. I excel at untangling legacy codebases;

I dive in quickly to create rigorous testing frameworks, fix bugs,

add features, document code and procedures, and upgrade infrastructure.

- I can advise you on any of the above areas, and/or consult on an ongoing

basis. I can help plan your enterprise architecture, working solo

or with your existing team. Need to start from scratch? I can get

your start-up off the ground. Need to integrate new systems into a

heterogeneous environment? I can make all the pieces fit.

Selected Work Experience

Software Engineering

- Ran a company's evaluation of Catalyst (Perl MVC, similar to Ruby on Rails).

Wrote a prototype and chose libraries. Then, with two other consultants,

rewrote a legacy, profitable web site in under six months.

Skills used: Perl, Catalyst, PostgreSQL (as database architect)

- Rewrote a legacy trading system as an intranet SOAP service, using OO Perl

and SOAP::Lite. Created a regression test framework to ensure identical

results with the legacy system. Wrote client code in Java (Apache Axis) and

Perl (SOAP::Lite); resolved interoperability issues. I also built and

administered the development web server (Apache 1.3 with mod_perl).

Skills used: SOAP web services, Perl, Java, Apache/mod_perl,

regression testing

- As lead architect, designed an Apache app server using custom mod_perl

handlers.

Skills used: Apache, mod_perl, REST/XML, technical writing

- Performance-tuned a legacy mod_perl app (for CPU and memory usage).

Skills used: Apache, mod_perl, performance tuning

- Wrote a GUI visualizer for SIP (Session Initiation Protocol) transactions.

Using this tool, performed end-to-end testing, created Postscript network

diagrams, and wrote system documentation.

Skills used: Perl, Tk, understanding of VoIP protocols, technical writing

- Added audit-mandated data to an in-house security and Sarbanes-Oxley

database. The new code monitored all Sybase, Windows, Unix, and NIS+

group access, and raised exceptions for unauthorized privilege grants.

Extended a sophisticated database schema (using association tables,

dictionary tables, and other meta-relational concepts) to accommodate

these new data.

Skills used: ColdFusion, Perl, NIS+, Unix, Sybase, SQL (DML and DDL), XML

- Wrote a stand-alone REST provisioning server in C++, with client code

in Java. Client and server communicated by XML over a trivial HTTP subset,

which I implemented from scratch. Contents were VoIP provisioning data.

Skills used: C++, Java, TCP/IP server programming, HTTP, XML

- Wrote plugins and documentation for the Java smart web proxy WBI (similar

in concept to Greasemonkey, but much preceding it). Later this product

was commercialized as the core of an IBM XML transcoding engine.

Skills used: Java, technical writing

Teaching, Consulting, and Writing

- Conducted a company's evaluation of Perl Web templating solutions:

Perl ASP CPAN module, Template Toolkit, and HTML::Mason. Recommended

HTML::Mason, resulting in its adoption as the official company standard.

Skills used: Perl, technical writing

- Helped plan curriculum, write online materials, and teach courses for USAIL,

a first-of-its-kind online course for training systems administrators.

Taught lecture sessions; coached students through hands-on training.

Skills used: Unix system administration, technical writing, teaching

System Administration

- Built a Linux shop's desktops, servers, and network from 15 people at

the time I joined to over 70 when we were acquired by Cisco. Handled all

functions from building the network to purchasing hardware to administering

systems. Migrated network to new office. Hired an assistant sysadmin.

Skills used: Unix system administration (Red Hat Linux), sendmail, NFS,

DHCP, TCP/IP networking, change management, crimp tool

- Acted as a consulting/troubleshooting sysadmin for a university of

30,000 students. My team of five handled all departments and labs;

I was the Linux and Solaris specialist. Between putting out fires,

we created USAIL to empower grad students and department IT staff

to administer their own systems.

Skills used: Unix system administration (Solaris, Red Hat Linux, Slackware

Linux), NFS, NIS

Education

BA (cum laude) with majors in cognitive science and classical studies - Greek,

Indiana University, 1995-1999

Professional Activities

Presented sessions on Asterisk IVR programming at the first O'Reilly Emerging

Telephony Conference (2006) and at CodeCon (2006).

President since 2001 of San Francisco Perl Mongers (programming language

users group). Book and coordinate presentations by Perl celebrities,

authors, and local Perl luminaries.
