I build mobile apps that launch clean and keep working.
Fourteen years of both halves — across the US, Canada, the Gulf and India.
Rizvan Hawaldar, mobile and solution engineer. I've built for Justdial, Baker Hughes, Loop Health, Mphasis, NCR Voyix and Alshaya — mobile first, with the backend and ML inference work that keeps those apps fed.

Teams I've built for
Selected work
Four things worth opening.
A Dune
A remote job platform that pulls openings from every source into one searchable place. Built end to end — search, aggregation pipeline, and the front end people actually use.
adune.app ↗Healthcare · Play StoreLoop Health app
Insurance and care in one React Native app: claims, policy details, and real-time doctor consultations. Heavy focus on state correctness and keeping the app responsive on low-end Android.
View on Play Store ↗Logistics · Android4Tigo fleet platform
Native Android for truck fleet operators — live tracking, trip management and route work built around Maps, designed for drivers using it one-handed in a moving vehicle.
About the product ↗Tooling · open sourceAI visualization framework
Components for inspecting what a model is actually doing — inference traces and dataset shape rendered as something a team can read in a review, not a wall of logs.
See the repos ↗Track record
Fourteen years, eight teams, one habit: ship it properly.
- Full-stack delivery for product teams: mobile apps, APIs and the integrations between them.
- React Native, native Android and iOS work across insurance, finance and retail products.
- Performance and reliability work on apps already in the store — the unglamorous fixes that keep ratings up.
