Software for Navy RDCs - they basically double data entry info during recruit training on a paper in the day, then re enter it into their systems at night in personal time. made a fully offline capable little SPA to track the data and sync it later. saved 100s of hours each cycle. was challenging (pwa talking to soap..) but felt good

then it got pulled, shelved and never saw the light of day but this was after our time as contractors and i never heard why. but it's probably my most meaningful development aside some niche detection and warning sensor products
