About
Vikrant Jain
I'm a mobile application engineer focused on turning complex product ideas into reliable, intuitive mobile experiences.
5.5+ years building production iOS and Android applications. Flutter is the primary stack, with enough native, API and architecture depth to own a product past the first release.
The work spans AI assistants, real-time communication, maps and mobility, payments, and video surfaces. The constant is the same: understand the constraint, design the architecture, integrate the services, and ship something people can actually use.
Approach
How I Think About Software
01
Product First
Technology should solve a real user problem. Architecture follows the job the product has to do.
02
Architecture Matters
Clean boundaries make products easier to evolve when requirements change — which they will.
03
Performance Is a Feature
Fast interactions and a stable frame budget are part of the product, not a polish pass at the end.
04
Ship, Learn, Improve
Production feedback is more valuable than theoretical perfection. Instrument, observe, iterate.
Process
From Idea to Production
01
Understand
Understand users, business requirements and constraints before choosing a stack.
02
Design
Define architecture, flows and the technical approach that can survive the first year of changes.
03
Build
Develop, integrate, test and iterate against real devices and real APIs.
04
Ship
Deploy, monitor crash and performance signals, then improve what production actually shows.
