I deliver end-to-end product work across design and engineering: user research, UX/UI design, interaction & visual design, prototyping, usability testing, and production handoff. I also build full-stack proofs-of-concept for IoT and embedded systems, implement secure authentication flows (biometric, OTP, TOTP) and design blockchain-backed transaction flows where needed. Projects are scoped to combine product thinking with engineering feasibility.

My approach is collaborative and measurable:

• Discover: Stakeholder alignment, problem framing and user research.
• Prototype: Wireframes → interactive prototypes (Figma / HTML) to validate flows.
• Validate: Usability tests, analytics tracking & iteration.
• Deliver: Developer-ready assets, documentation, handoff & post-launch checks.

Pricing depends on scope and deliverables. I offer:

• Small product work / audit — fixed fee.
• Feature / redesign work — milestone-based or fixed scope.
• Long-term collaborations — monthly retainer.

I’ll propose the best model after an initial discovery call and a brief scoping conversation.

Timelines vary by complexity:

• Micro tasks (audit, small UI updates): 1–3 weeks.
• Feature designs & prototype validation: 4–8 weeks.
• End-to-end product design with research & testing: 2–4+ months.

Every proposal includes a timeline with milestones and review points.

Deliverables are tailored to the engagement and commonly include:

• Research summaries & personas
• Wireframes, interactive prototypes (Figma/HTML) and design specs
• Accessibility checklist & usability test reports
• Developer handoff assets (components, tokens, documentation)
• Optional: Proof-of-concept code for IoT/embedded or blockchain flows

Security is integral to my work. Depending on the project I follow secure-by-design principles, threat modeling, and best-practice authentication (e.g., AES/SHA, TOTP, secure biometric flows). I also advise on data minimization, encryption (in transit & at rest) and safe cloud configuration. For sensitive work we can sign an NDA prior to any data exchange.

Yes. I build interactive prototypes and simple embedded proofs-of-concept (e.g., Arduino / ESP8266/ESP32, RFID, load-cells, sensors) and integrate them with cloud backends for demos. For production hardware I collaborate with manufacturing/embedded partners and provide the system architecture and firmware handoff.

Send a short brief via the Contact page(project goals, timeline, budget range). I’ll review and propose a 15–30 minute discovery call to align expectations and scope. After that you’ll receive a written proposal with milestones and costs.
