01 · About
Engineering judgment shaped by ownership.
I’m an Android engineer who likes owning the difficult middle: the space between a clean architecture diagram and a product that behaves reliably on a real user’s phone.
My work spans media and offline systems, legacy modernization, product performance, release delivery, and mentoring. Building MetroYar end to end sharpened my product instincts; production work on Parande, Vidzy, Didimoon, and enterprise applications deepened my approach to scale, stability, and cross-functional collaboration.
I use AI-assisted workflows where they improve analysis and delivery, while keeping engineering decisions reviewable, testable, and owned by the team.

Problem
Metro information can be fragmented, connectivity is not guaranteed underground, and a trip often requires more context than a static map.
Product
MetroYar combines offline station-to-station routing, nearby discovery, maps, timetable context, favorites, and sharing in one focused Android experience.
Engineering
Jetpack Compose and Clean Architecture keep product iteration structured while an offline-first flow protects the core journey from network availability.
Outcome
An independently released product with 47K Bazaar installs and 14K Myket downloads, maintained through iterative store releases.
Offline-first core journey
Offline routing
Choose origin and destination stations and calculate a route without depending on a live connection.
Nearby & mapped stations
Find nearby stations or explore their location in the wider city context.
Metro essentials
Access the latest metro map, timetable information, favorites, and route sharing.
Iterative releases
Version 1.5.0 adds weather and air-quality information alongside interface refinements.
High-level architecture
A simple boundary around the journey that must always work.
This diagram intentionally stays at system level and avoids claiming implementation libraries that are not publicly verified.
