I build useful apps and tools for real people.

How I go from an empty Expo project to a Play-Store-ready Android app. Navigation, native APIs, offline storage, building APKs and handling the release checklist — everything in one practical, project-based file.

The JavaScript I actually use daily, written for someone starting from variables and ending comfortable with async patterns, prototypes and the event loop. 62 pages of syntax, gotchas and small runnable examples.

Everything from ER diagrams to normalization and transactions in one file. Written in plain language with worked examples for every SQL concept, covering my full Sem 4 syllabus plus the extras that showed up in university papers.
