Agreed.

Also, be aware that many non-expert attempts to develop compression algorithms turn out to be flawed. However, it sounds like you've developed a compression pre-processor specifically targeting JSON-like structures, which seems like a much more plausible accomplishment than a non-expert developing a brand new general-purpose compression algorithm that can beat LZW.

All that said, if I were considering hiring you I would be much more interested in your ability to rigorously analyze the strengths and limitations of your algorithm (rather than the algorithm itself). Plus, without that rigorous analysis it makes it much more difficult for me to judge the quality of your algorithm.
