Established an independent consultancy focused on transitioning traditional software workflows to AI-First architectures. Operating under the brand "Efkan Works" to design, build, and deploy cloud-native mobile solutions.

• Production-Grade App Development: Architecting and deploying cross-platform mobile apps (e.g., Hush) to App Store & Google Play. Expert implementation of RevenueCat for hybrid monetization models and robust CI/CD pipelines.

• Engineered an "Offline-First" AI architecture: Developed a React Native (CLI) baby monitor app utilizing on-device machine learning (TensorFlow Lite) for zero-latency, privacy-compliant smart cry detection without cloud audio processing.

• Architected a serverless multi-parent pairing system: Built an anonymous, cross-device pairing architecture using Firebase (Anonymous Auth, Firestore, Cloud Functions), enabling sub-second FCM push notifications without requiring mandatory user accounts.

• Led full-cycle product development: Managed the entire lifecycle from UI/UX design (implementing a dark-mode, melatonin-safe color system) to RevenueCat subscription integration and automated CI/CD deployment via Fastlane.

• Developing agentic workflows utilizing Claude Code and Antigravity to automate coding tasks and improve developer velocity.

As a Team Lead Engineer, I oversaw the development of several key applications, including a mobile e-commerce app, a support platform, a survey application, and the Monster Ambassador Program application.

Furthermore, I contributed to the development of a front-end control center application for Monster Notebook customers, enabling them to access hardware features.

Additionally, I spearheaded the development of an AI Chatbot application, although its product was subsequently suspended due to the rapid advancements in AI technology.

Led a scrum team that is responsible for developing the Skulp app.

Worked on the project Metance.com (formerly a.k.a Vault)

• Developed new features and maintained existing modules for a content management product.

• Improved UI rendering performance by 35% in certain components. Also implemented virtualized lists and optimized React component lifecycles.

Engaged in diverse software development projects, tailored to meet the specific requirements of various domains, including finance and e-commerce.
