Work Experience

Frontend Developer

Twwios Technologies Pvt. Ltd. (Last Minutes Deal)

Sep 2026 - Present

Built the frontends of three business web apps: ShareWork (a fixed-price services marketplace), NoShow OS (appointment booking) and Corporate Lead Vault OS (lead management). Reworked all 14 pages of the Salon & Spa OS frontend. Integrated the UIs with Express/MongoDB REST APIs through Axios and fetch clients that attach JWT bearer tokens and handle expired sessions (401) centrally. Built reusable components (modal, table, toast) and loading/empty/error states. Developed dashboard workflows: a booking calendar with 30-minute slot selection, staff attendance with Excel export (ExcelJS), lead tracking with status and source filters, and a marketplace project flow covering agreement, simulated escrow, delivery and approval. Debugged Express/Mongoose backend issues while connecting the frontends to the APIs, including normalizing inconsistent route and model file-name casing. Worked with MongoDB data models throughout the integration. Collaborating with backend developers in shared GitHub repositories. Currently developing the frontends for FitTrack Community and Flat Town.
