Team Leadership & Development

• Coached team members to improve skills, foster innovation, and maximize contributions.

• Created a cohesive, empowered, and results-driven team environment aligned with project objectives.

Technical Decision-Making

• Designed and evaluated scalable, high-performance software architectures.

• Translated functional requirements into detailed software specs aligned with client expectations.

Stakeholder Collaboration

• Acted as the primary liaison between clients, functional stakeholders, and technical teams.

• Managed dependencies and facilitated cross-team collaboration to resolve technical and organizational blockers.

Quality Assurance & Delivery

• Reviewed deliverables to ensure high quality and adherence to standards.

• Proactively addressed issues, prioritized blockers, and maintained delivery momentum.

This role demanded a unique blend of technical depth, strategic insight, and leadership, enabling the team to deliver innovative, high-quality solutions in a complex, fast-paced environment.

• Redesigned and rearchitected an application for LED driver programming and configuration, transforming it into a modern, scalable, and strategic solution. Initially developed in C++ and Qt, the application served as a web server exposing a JSON-RPC API and interfaced with LED drivers via dedicated hardware to identify connected devices, determine protocols, and translate user input into device-specific commands.

Recognizing the limitations of C++ for a web server with database integration, I rearchitected the application using C# and .NET Core, enabling cross-platform compatibility (Windows, macOS, and future mobile support). Key Responsibilities and Achievements:

• Product Strategy and Technical Leadership:

• Led the transformation by aligning technical solutions with business goals through close collaboration with stakeholders.

• Translated business requirements into actionable technical specifications and prioritized features for maximum impact.

• Architectural Redesign:

• Analyzed undocumented legacy C++ code to understand protocols, dependencies, and subtle intricacies.

• Designed a future-proof architecture tailored for scalability, maintainability, and efficient cross-platform deployment.

• Developed a new database schema supporting the revamped application and the broader tooling ecosystem.

• Implementation and Execution:

• Oversaw project planning and execution, ensuring smooth delivery and long-term maintainability.

using ASP.NET Core.

• Enhanced the application's ecosystem with improved database integration and backend compatibility

• Applied expertise in C#, C++, and database design to deliver a robust and efficient solution.

This project demonstrated my ability to lead end-to-end product transformations, combining technical expertise, strategic planning, and collaborative stakeholder engagement to deliver innovative, scalable, and business-aligned software solutions.

• Led the integration and enhancement of embedded solutions for OEM customers, transforming bespoke software into a scalable, general-purpose product while maintaining high standards of quality and performance. Key Responsibilities and Achievements:

• Product Evolution and Scalability:

• Enhanced the product from a custom solution requiring OEM-specific modifications to a versatile, scalable platform, improving maintainability and customer satisfaction.

• Collaborated closely with customers to integrate solutions, customize libraries, and address specific requirements while ensuring seamless deployment.

• Feature Development and Process Optimization:

• Implemented new features to meet system and customer requirements, adhering to rigorous standards.

• Developed and improved Android system libraries, services, and HIDL interfaces, ensuring compliance with Google certification standards.

• Worked on internal tools using C# to streamline processes and improve operational efficiency.

• Technical Expertise in Embedded Systems:

• Fixed and optimized bugs in existing libraries, adapting them to meet OEM needs.

• Leveraged extensive knowledge in embedded systems, including C, C++, C#, Java, Android, and BLE, to deliver robust and reliable solutions.

This role demonstrated my ability to lead technical initiatives, balance customer-specific demands with product evolution, and deliver scalable, high-performance solutions. By combining technical expertise with a strong focus on customer needs, I successfully aligned product development with business goals and long-term scalability.
