About

Possible rewritten summary: As the Mobile Lead at NuShala, I design and build Android & iOS apps that leverage animation, location, and maps to create engaging and immersive user experiences. I have been developing iOS apps since 2017, using both Swift and Objective-C, Flutter, Dart, and I am passionate about exploring new technologies and solving complex problems. I have worked on multiple projects that involved advanced computation techniques, such as multi-threading, GPU acceleration, and smart data structures, to optimize the performance and functionality of the apps. I also value security and data integrity, and implement best practices such as HTTPS, secure password hashing, and encryption. I enjoy collaborating with other developers, designers, and stakeholders, and contributing to the success and growth of the company.

Work experience

SDE3 at Wiom, Apr 2024 - Present · 2 yrs 5 mos, Lead design, development, and maintenance of the Wiom Flutter mobile app serving users of a high-speed, affordable WiFi service. Architect and ship new features, integrate RESTful APIs, and enhance end-to-end app performance. Identify performance bottlenecks through profiling and optimize critical user flows for a smoother, more responsive experience. Reduce app crashes and ANRs by analyzing stability reports, triaging root causes, and driving fixes across releases. Modularize API calls into smaller requests to reliably serve users on low-bandwidth networks. Build WiFi router provisioning and device-onboarding flows inside the Flutter app — handling captive portal detection, local network discovery, user-agent customization, and single-file Flutter Web deployment for on-device hosting. Minimize APK size to improve installs, retention, and device compatibility. Collaborate with designers, product managers, and backend engineers to deliver cohesive, high-quality user journeys. Own release cycles and Play Store deployments, ensuring smooth, on-schedule rollouts. Integrate AI-assisted development workflows (Cursor, GitHub Copilot, ChatGPT, Claude) into day-to-day engineering, accelerating feature delivery, reducing boilerplate, and improving code review quality. Prototype LLM-powered product features using OpenAI and Anthropic APIs — from prompt engineering and response parsing to in-app integration on Flutter clients. Conduct code reviews, provide constructive feedback, and mentor junior developers on mobile best practices and effective use of AI coding assistants.
