Hi, I'm Andika. I engineer resilient, reactive mobile applications and real-time streaming interfaces that bridge the gap between hardware tracking protocols and client experiences.
Engineering Specialties
Expertise in native Android and cross-platform Flutter engines. Proficient in managing complex UI state machines cleanly using RxJava, Coroutines, and asynchronous Flows.
Specialized in event-driven streaming web apps using RxJS, orchestrating live asset intervals, processing asynchronous events, and telemetry feeds dynamically.
Deep background configuring cellular/satellite hardware trackers, managing direct server target routes, intervals, and engineering rock-solid backend APIs.
Production Telematics & Mobility Architectures
From high-frequency land fleet management platforms to dedicated open-sea asset telematics and native logistics pipelines.
Architecting a seamless cross-platform mobile app and a custom, reactive web-extension ecosystem to handle IoT telematics.
Engineered a public-facing monitoring page utilizing RxJS observables and the Google Maps API. Subscribes to live telemetry streams to update asset positions fluidly in real-time without jarring page refreshes.
Built a complete web manager panel giving administrators absolute control over data access. Includes user permission toggles for token generation alongside a dual-layered audit ledger logging precisely how many times links are generated versus how many times they are accessed.
Maintained an enterprise fleet interface using RxDart streams and Provider state management to seamlessly render asset tracking parameters, analytical charts (fuel/temperature), and historical location playback over the Google Maps SDK.
Integrated localized Point of Interest (POI) matching, driving a simplified dashboard object counter (In-Zone / In-Route) alongside a dedicated menu displaying active asset distributions across defined POI boundaries.
The entire lifecycle relies on highly optimized JSON payloads processed through RESTful services, ensuring low network overhead when mobile devices ingest multi-asset coordinate arrays over cell networks.
A specialized telematics engine dedicated to maritime asset tracking, designed to monitor sea-based vessels such as ships and marine hardware platforms. Built in Flutter utilizing an exact default Material 3 layout system, the mobile app runs over a distinct backend built using VB.Net (REST API). It directly integrates third-party Weather APIs to populate live marine metrics—including wave height, wind speed, and sea-states—as rich additional detail when an operator selects an asset.
A robust, native Transportation Management System (TMS) architected for end-to-end cargo transit visibility. Engineered from the ground up in native Kotlin using RxJava to process high-frequency reactive state updates throughout transit routines, the client platform equips drivers with interactive delivery timelines, secure signature fields, and camera-bound photo workflows for unalterable Proof of Delivery.
An enterprise mobile recovery platform built inside native Kotlin designed for field agents to execute installment collection workflows safely. Features a runtime-driven dynamic form engine that custom-builds fields from volatile backend configurations. Modernized the app's security completely by transitioning from standard JWT configurations to corporate Single Sign-On (SSO) standards using OAuth2/OIDC webview delegation.
Analyzing metrics and architecture details for the next production system entry.
