Available: APL programmer with extensive experience (added: 2021-03-04)

I have been interested in APL for 42 years, and have been a programmer for 35 years, using NARS2000 APL for the last decade and half or so.

I'm in Baltimore, Maryland, USA, and I'm not really able to travel. Since our department imploded, I haven't been able to find a job in my field because the languages I know, no one hires for, and the ones they are looking for, I don't have job experience in. No one wants to take me on as entry level, because I have too much experience, so I have been working as a math tutor since the summer of '19. I do, however, know APL. For example, I solved 121 of the project Euler problems using it.

Contact me on LinkedIn if you have an opening for me.

This is Vinny Sanchez from Genzeon Corporation.

We are looking to fill a APL developer with one of our Direct clients. If you are interested, please share your updated resume ASAP.

Job Title: APL developer Location: Remote/ Occasional travel to Philadelphia, PA for meetings Duration: 12–24 Months contract

Job Description: Searching for an APL developer, mostly maintenance/support but some new coding for enhancements, etc..

The client runs an older COLI/BOLI system (SOLAR) that still pays out on policies bought during the 80’s and 90’s. COLI/BOLI is corporate/bank owned life insurance. Companies/banks/etc bought life insurance policies on their employees and customers as long-term investments. They don’t sell them anymore, but they must pay out on them until they all expire. The solar system manages all those policies and was written in APL. It scrapes the social security database every night to see if any policy holder names died the day before and then processes the policy payout.

Needed: Translate Economic System to APL (added: 2022-09-08)

I'm working on a system of incentives that makes it only profitable for companies to do good, and a set of tools that allow communities to define for themselves what counts as good. If this seems interesting, there's more context here.

I've built a toy version of the system in a tool called Coda. Coda has a nice interface and a minimalist formula language, however, it's not amenable to mathematical proof.

I believe that re-implementing the process found there into APL would be illuminating from a research perspective.

I'd like to hire a skilled APLer who can write idiomatic APL. I'm very interested in the deep mathematical insights that converting to APL might yield.

I recognize that this is likely to be a very challenging task. It will require reverse engineering a system you've never seen before, and considering the high level game theory of the system.

Here's what the system looks like to be reverse engineered:

And there's a second bit that I'd also like to capture.

If you'd like to find a time to connect, here's a booking link for 15 minutes.
