Applied Infrastructure Conservatory

Learn to build software, understand it, and keep it useful.

Applied Infrastructure Conservatory is David Kirby’s practical teaching work. Students develop applications for their work or their own use, learning how to build, deploy, maintain, and take responsibility for them.

The practice includes staff development for financial companies and instruction for people with varied technical and educational backgrounds. A useful project provides the starting point.

Learning through real projects

Student projects have included:

  • A vice president building a secure virtual data room to organize confidential documents, manage access, and facilitate the exchange of information with equity partners.
  • A mixologist developing a food-logging application, translating an everyday personal interest into a working piece of software, from initial concept to functional prototype.
  • A people team designing a bespoke resourcing application to coordinate personnel, track availability, and manage assignments according to the particular needs of their organization.
  • A financial analyst building a market intelligence platform to collect, organize, and interpret financial information, transforming disparate sources into useful commercial insights.

How Instruction Works

The Conservatory has no fixed curriculum or academic calendar. Each course of study is organized around a real project, with instruction following the interests, experience, and practical needs of those involved. Most arrangements consist of a half-hour meeting every week or two, supplemented by informal questions over telephone or email. During periods of active development, we may meet daily. As projects mature and their operators become more independent, our meetings naturally become less frequent.

The work is wonderfully varied. A social media manager is developing an event management system incorporating memberships, payments, newsletters, contact enrichment, and outreach. A vice president is building a virtual data room for equity partners, an undertaking that has progressed from initial development to almost entirely independent administration. Our fortnightly conversations are now largely a formality, which I consider a rather satisfactory outcome.

Projects in regular service

Several projects have already entered regular service. A mixologist uses a food-logging application of their own construction every day; formal instruction has concluded, though we remain in correspondence and I occasionally look after the server. A people team operates a bespoke resourcing system serving more than a hundred daily users, with roughly thirty online at any given time. We ordinarily meet twice monthly, returning to more frequent collaboration whenever new development is underway.

Another ongoing investigation concerns a financial analyst developing a market intelligence platform. Our conversations involve mathematics, modeling, and the design of systems for collecting and interpreting commercial signals. In this arrangement I suspect I am learning more than I am teaching. Together with other members of the team, we are exploring how to represent a considerable variety of financial observations within a common schema.

Growing independence

My own involvement varies with the circumstances. I occasionally contribute code, perform server maintenance, or help investigate an especially troublesome problem. But the ambition is always to become progressively less necessary. The most satisfying result is a capable practitioner who knows their own instruments, understands their operation, and carries the work forward without much assistance from me.

Building & operating

Building an application is often the beginning of a much larger education. Along the way come questions of data, access, deployment, maintenance, and the many small decisions that arise once people begin using the software. The Conservatory explores these subjects through practical work, making use of AI-assisted tools while developing a deeper familiarity with the systems they help create.
