Byron D.

Senior Software Engineer | Windows, Android & Hardware Integration

Whether you need to revive a legacy system without breaking its core logic or build it from scratch, and it has to be stable under tough conditions, I provide the technical reliability your project requires. Clients come to me when they need software that “just works” in demanding scenarios: industrial control, fleet/corporate tracking, self-service kiosks, field sales tools, or data-heavy enterprise sync. I prioritize solutions that reduce operational headaches, improve user experience, and scale without constant fixes. I write code designed to be maintained by others. My goal is for your team to be able to take over the project in the future without having to decipher complex logic or deal with accumulated technical debt. If you have a system causing operational friction or a project that requires a stable foundation from day one, feel free to reach out. We can discuss your current architecture and determine the most efficient path to stabilize or scale your solution. ===What I can do for you=== * Modernize old Android or desktop applications: migrate code to modern languages and architectures, improve performance, add offline support, handle complex local storage with safe migrations, and make synchronization with backends more robust and fault-tolerant. * Build responsive, hardware-connected apps: implement asynchronous communication, custom UI components for touch or specialized interfaces, background services (location, monitoring, telemetry), power-efficient processing, and permissions handling across Android versions. * Create reliable integration middleware or connectors: design asynchronous layers for heavy data transfers between local databases, APIs, or accounting/enterprise systems, with strong validation, logging, error recovery, and minimal downtime. * Ensure apps stay responsive and safe: use multi-threading, coroutines/Flow/reactive patterns, state machines, and safeguards to prevent crashes, race conditions, or hardware issues—even during intensive I/O, real-time updates, or long-running operations. === Technical Toolkit === * Languages: Kotlin, C#, Java * Android: Jetpack Compose, Coroutines, Flow, Room, Koin/Hilt, WorkManager. * Desktop: JavaFX, Swing, WPF, Avalonia. * Architecture & Patterns: SOLID, MVVM, Reactive Programming, Concurrency, Asynchronous I/O. * Integrations: Serial Communication (CNC/HID), SOAP/REST, SQLite, SQL Server, ERP Connectors.
