Architected and built a shared platform ecosystem (authentication, billing, UI foundations, analytics, AI, and translation services), standardizing best practices across teams and reducing duplication to accelerate product feature delivery.

Directed multiple cross-functional engineering squads (backend/frontend) to ensure consistent execution, smooth delivery, and alignment with product portfolio goals from discovery to production.

Contributed directly to company-wide strategic initiatives and owned critical architectural decisions, reporting to the CEO, to balance development speed, system reliability, and long-term maintainability.

Defined and executed the long-term technology roadmap, aligning architectural designs, scalability targets, and deployment strategies directly with overarching business priorities and product growth objectives.

Mentored and upskilled senior engineers and architects, elevating standards for code quality, design patterns, review processes, and documentation, significantly improving maintainability and onboarding efficiency.

Developed and launched a multilingual subtitle capability supporting 10 languages, significantly increasing content reach, ensuring accessibility compliance, and boosting international user engagement.

Spearheaded the launch of 'Sale Rocket,' an AI-driven tool that transformed raw sales conversations into measurable KPIs and actionable insights, enabling teams to improve coaching, accelerate gap closure, and standardize execution.

Achieved significant cost optimization by operationalizing transcription and Large Language Model (LLM) pipelines, fine-tuning models for target accuracy, and controlling inference spend within business-aligned quality thresholds.

Developed custom area/volume measurement tools and 3D annotation workflows for the Observance construction management platform, streamlining estimating, progress validation, and issue tracking.

Engineered an FR-based attendance reporting module for Observance, providing project managers with near real-time workforce insights and optimizing resource allocation.

Architected and built an end-to-end accident reporting and ambulance dispatch platform for a leading hospital, including cross-platform mobile apps and a web admin console, improving incident intake and response coordination.

Implemented a robust REST API with a custom AWS backend for real-time ambulance/case tracking and live-stream feeds, ensuring reliable data exchange and system performance.

Led performance optimization for an FR-based attendance monitoring system, drastically reducing initial page load from ~90s to <300ms and report generation from ~10 minutes to <1 minute for 1M+ logs through caching, sharding, and Node.js backend optimizations.

Improved responsiveness and user experience of the Flutter employee enrollment app through targeted performance tuning and workflow refinements.

Developed core monitoring modules for a healthcare platform, significantly improving clinicians' ability to track patient vitals and identify critical health trends.

Implemented real-time ECG streaming utilizing WebSockets, ensuring minimal latency, high reliability, and seamless UI updates for critical patient data.

Managed high-concurrency subscriptions for multiple patients and vital signals (ECG, SpO2, respiratory rate), optimizing event handling and client-side rendering to significantly reduce lag and enhance user experience.

Built automated insight reports from patient metrics, surfacing anomalies and trends to healthcare staff, which reduced manual analysis efforts and improved proactive care.
