I, too, am over 60 and presently employed as a C# Web API developer and SQL Server DBA, pushing to Microsoft Azure. My languages are Python, Java, C# and databases PostgreSQL, SQL Server, SQLite, and MySQL, in that order of preference. That being said, it took oodles of applications and interviews, as well as six months, to get this position. Things I learned during this latest job transition are as follows:

Tweak the resume as appropriate, for example, just list the last twenty years or so of experience. I would send out two resumes, one under an alias, another under my real name. Sometimes the alias had the full experience, sometimes it would have just the last twenty years. I would receive callbacks on the twenty-year resume, but not on the full resume with 38 years of experience. Age discrimination does exist and it starts at your resume and those that review it. Open up a GitHub account and start posting your projects, even hobbyist projects of yours, for those that are reviewing you as an applicant to see that you're familiar with open-source and GitHub as well. A couple nights a week, pick a small, self-educational, project and work it to its conclusion. Presently, I'm focused on Python 3 as it seems to be a rather popular language with the added side benefit of being a total blast in which to program. Be sure to work with SQL as well. I'd suggest PostgreSQL and SQLite 3. Start now, without delay, as you'll need the projects to be in GitHub later. Sometimes it's hard to come up with a project of interest. When I'm confronted with that, I'll go to my Kaggle.com account and look around for some data science competitions upon which to work. The benefit of Kaggle.com is that you can the source code of others, which is helpful in learning new ways to solve various problems. On a personal note, get rid of the grey beard and, if appropriate, lose some weight. It's no secret that interviewers tend to skew towards those similar to them and radiating an aura of self-respect and energy. When you interview, you're selling your present knowledge and energy, as well as your past experience. Apply, apply, apply, and when you're tired of applying, do a self-educational side project, post it to GitHub, and then apply, apply, apply, until your fingers ache from the typing. This is my fifteenth or sixteenth development/DBA job in a thirty-five year career. Two of my jobs were over seven years each, several of three years, a few of two years, and some as little as three weeks. Persistence pays off. In summary, apply, apply, apply...
