How does Mania bridge design and engineering?

This assistant is an in-progress AI experiment. At this stage, it’s meant to demonstrate the idea, not a complete working implementation.

Pollfish

Market Research / SaaS platform

Pollfish is a global market research platform used to design surveys, target audiences, and analyze results at scale. I lead the design of the whole survey’s experience. The challenge is building a flexible system for complex logic and large-scale data, while keeping the experience intuitive.

Questionnaire Builder

The Questionnaire Builder is the core of Pollfish’s survey creation workflow, allowing users to design, structure, and manage surveys with support for complex logic and advanced configuration.

I lead the design of the experience, structuring how questions, logic, and settings are created and managed within the builder. The focus is on making complex functionality easier to use, without limiting flexibility for advanced research needs.

AI Builder

The AI Builder brings natural-language survey creation directly into Pollfish’s core workflow. Users can generate, refine, and restructure questionnaires using AI, including support for complex research methods and advanced survey logic.

I led the UX strategy and interaction design to ensure AI enhanced, rather than disrupted, complex survey logic and professional research standards.

Multiple Audiences

Designing a system that allows researchers to run surveys across multiple audiences, each with different targeting, quotas, and constraints.

I led the design of the experience, structuring how audiences are created, compared, and managed within a single project. The focus was on maintaining flexibility while ensuring feasibility and clarity at scale

Construction collaboration platform

Project Alpha (confidential codename) is a construction collaboration platform that helps teams manage tasks, properties, and contractors. I’m designing the product from an early stage, structuring core workflows and how key entities interact. The focus is on bringing clarity to fragmented processes while maintaining flexibility.

CtrlEat

Nutrition - Aware Food Delivery

Designing an MVP for a food discovery app that tailors recommendations based on users’ dietary preferences. I worked as the sole designer, structuring how preferences are captured and translated into meaningful suggestions. The focus was on turning diverse user needs into a clear and usable system.

Minddy

Habit Building App

Designing a habit and wellbeing app exploring how users build routines and track progress over time. As part of my thesis, I defined the core experience, structuring how habits are created, tracked, and supported through guided sessions and reminders- translating behavior-driven concepts into a clear and usable system.
