What processes and areas of public sector? Those would be useful to software companies selling into goverment. So don’t undersell yourself.
Careful that a lot of software is outsourced to India and other locations. In terms of skill sets - don’t replicate those available in low cost locations. It may be better doing a maths/statistics degree part time - that opens up data science, computational analytics for banks, energy companies etc but also opens up to quantum computing.
