Mohammad Usama

Product-focused Flutter engineer with 2+ years of experience shipping healthcare mobile applications used by clinical teams in high-stakes emergency environments. Delivered 575+ PRs across two production apps, spanning real-time communication, AI-assisted clinical workflows, E2E encryption, biometric auth, and CI/CD automation. Collaborates cross-functionally with backend, product, and design teams from API contract design to pixel-perfect Figma implementation and actively leverages AI-assisted development tooling (Claude Code, Gemini, Figma MCP) to accelerate delivery without compromising quality.

Software Engineer at Sofstica Solution (2025-11 – Present)

• Revamped the RRT Copilot, the app's core AI feature by rebuilding state management for real-time response streaming, implementing complex clinical data UI, and adding graceful timeout/fallback handling when the AI backend is unavailable; directly improving speed and accuracy of emergency medical interventions.
• Designed and shipped a Text-to-Speech (TTS) announcement system for emergency calls using flutter tts, enabling hands-free, zero-delay alerts for critical patient events and reducing on-scene response time.
• Automated SBARI medical handoff documentation by parsing structured clinical data into AI-generated summaries, reducing manual documentation time for clinicians by an estimated 30%.
• Established a CI/CD pipeline for QA and Staging environments using GitHub Actions and Xcode Cloud, cutting release cycle time by 50% and enabling automated bot-driven deployment tracking.
• Actively collaborate with backend team on API contract design to optimize data payloads and reduce over-fetching; partner with product and design teams on feature scoping and Figma design validation before development begins.
• Conduct thorough PR reviews and drive code quality standards across the mobile team; leverage AI-assisted tooling (Claude Code, Gemini CLI, Figma MCP server) to deliver pixel-perfect Flutter UIs at record speed.

Junior Software Engineer at Sofstica Solution (2024-06 – 2025-11)

• Built the Rapid Response System (RRS) from the ground up a Flutter-based emergency coordination platform providing predictive alerts, real-time team communication, and critical patient notifications for hospital staff.
• Implemented End-to-End (E2E) chat encryption using the PointyCastle library (RSA key pairs + AES), securing sensitive patient data across all clinician communications and achieving HIPAA-compliant messaging.
• Engineered real-time group and individual chat with Socket.io and WebSockets, including message replay, media sharing (images/videos), forward/reply threading, and message-seen indicators increasing team communication efficiency during emergency responses by 40%.
• Integrated on-demand EHR data synchronization via Dio with background sync logic, ensuring 100% data consistency between the mobile app and hospital Electronic Health Records systems.
• Delivered biometric authentication (FaceID / TouchID) using local auth and flutter secure storage, reducing clinician login time by 85% and login errors by 90%.
• Shipped multi-language support (Arabic/English) with a custom flutter localization workflow, expanding accessibility for global medical staff across localized patient status interfaces.
• Implemented VoIP-triggered push notifications and DND-bypass alerts for critical patient events, enabling faster on-scene response when standard notification channels are suppressed.

Flutter Fellow at Bytewise Limited (2023-03 – 2023-06)

• Delivered production-ready Flutter features implementing network requests (Dio), Google OAuth, and clean architecture principles within a competitive 3-month fellowship program.
• Recognized as a top performer among 700+ interns for exceptional output and on-time delivery under tight deadlines.
