I conceptualized and developed an AI-powered coding tutor designed to revolutionize learning.

My role was holistic, starting with market research to ensure product-market fit. I crafted the product design, focusing on intuitive UI/UX, resulting in wireframes, mockups, and user journeys that embody clarity and engagement.

As the project’s architect, I drafted the scope, devised strategic roadmaps for both immediate and long-term goals, and distilled the project backlog into actionable user stories. My technical background shone as I documented requirements and engineered a robust system design encompassing a relational database, integrated APIs (including OpenAI’s GPT-4), and a web platform. The AI algorithm, my proprietary design, combines generative data from GPT-4 with a curated learning path, creating personalized educational experiences.

My hands-on development approach, coupled with thorough alpha and beta testing involving real users, ensured a user-centric product ready for market introduction.

I developed a personal productivity tool that uses voice input and GenAI to streamline daily email management. The agent reads emails aloud, summarizes key points, and generates suggested replies using LLMs and voice-to-text processing. Built as a lightweight prototype for solo use, the tool integrates with Gmail and OpenAI APIs, offering hands-free interaction for improved focus and faster task handling.

I managed a team of 10 software developers, 2D and 3D artists, game designers, testers, and marketers for 10 months to release Disco Dave, a mobile game produced under the AmusedSloth brand.

Disco Dave was featured by Apple and received the “Best Kids and Family Game” award at Casual Connect, Tel Aviv, 2016. I created the entire game roadmap, decided on the major milestones, and coordinated the production activities, from the prototype, alpha, and beta testing sessions to the main release and then subsequent update releases. I established KPIs and defined art and game development processes using a hybrid of Kanban and Scrum. I also created project documentation templates, which helped reduce the studio’s production timeline from 2.5 years to just 10 months. The game was the studio’s first that broke even, reducing the loss that the studio had had with the previous titles.

The game was developed in Unity 3D and released worldwide on iOS, Android, Windows Phone, and Fire OS, as well as in local stores in China and Japan.

I managed a team of 10 software developers, 2D and 3D artists, game designers, testers, and marketers to release Super Pet Hero, a mobile game produced under the AmusedSloth brand.

Super Pet Hero is a mobile game that received the “Best Mobile Game” award at Casual Connect in 2017, Berlin. I created the entire game roadmap, decided on the major milestones, and coordinated the production activities, from the prototype, alpha, and beta testing sessions to the main release and the subsequent update releases. I established KPIs and defined art and game development processes as a mix of Kanban and Scrum. I also created project documentation templates, which helped reduce the studio’s production timeline from 2.5 years to 1 year.

The game was developed in Unity 3D and released worldwide on iOS, Android, and Windows Phone, as well as local stores in China.

The company was managing complex construction workflows (projects, payments, reporting) through multiple disconnected Excel files. This created data duplication and inconsistencies across teams, time-consuming manual reporting, and limited visibility into real-time project status and finances.

Mapped end-to-end workflows and identified inefficiencies in Excel-based operations. Translated findings into clear business requirements and defined a simple, user-friendly MVP focused on essential functionality. Designed a centralized platform for project tracking, payments, and real-time reporting, including OCR-based invoice processing and AI automations to reduce manual input. Created a phased roadmap with priorities, timelines, and cost/resource estimates, enabling structured execution and scalable development while ensuring alignment with stakeholder needs.

Replaced fragmented Excel workflows with a clear system design, improving visibility and reducing manual work. Enabled faster reporting, better decisions, and laid the foundation for a scalable, easy-to-adopt platform.
