Most useful when a team needs product thinking, systems judgment, and polished execution working together.

Best for

Startups and fast-moving product teams

I work best when a team needs product judgment, frontend polish, and full-stack execution in the same person.

Currently building

AI-native products and scalable web platforms

I'm especially interested in workflows where automation, good UX, and operational clarity all matter.

What I care about

Clear systems, calm UX, and real shipped outcomes

I like taking technically messy ideas and turning them into software that feels obvious to use.

What I'm especially interested in

AI-native workflows, thoughtful developer tooling, and products that simplify messy real-world problems without losing craft.

Featured projects

Selected work across AI, fintech, SaaS, and mobile experiences.

A few projects that best reflect how I build product-focused software.

Flagship project

2024.03 - 2025.08

Aivoes

Invoice capture, OCR workflows, and accountant dashboards for finance teams.

Why it mattered: Finance teams needed a faster way to upload, categorize, and review invoices across mobile and desktop workflows.

Key decision: Pair a simple mobile capture flow with a more powerful accountant dashboard so each user gets the right level of complexity.

Reduced manual processing work by turning scattered invoice handling into a searchable multi-client workflow.

Realtime AI translation

2025.10 - 2025.12

TIA

An on-device translation product built for lower-latency, cross-platform communication with a mobile-first user experience.

Role: Cross-platform product development, translation integrations, and Android app delivery.

Outcome: Turned realtime translation into a more usable product flow by balancing latency, clarity, and mobile-first UX.

Key decision: Keep the translation experience as close to the device as possible to reduce latency and make realtime use feel believable.

Consumer security platform

2023.10 - 2024.03

VirtualShield

Marketing, glossary, and product experience work for a privacy-focused VPN platform.

Role: Frontend implementation, responsive UI work, and UX collaboration with design.

Outcome: Improved the product's public-facing experience with polished pages and scalable content flows.

Key decision: Use clearer content structure and calmer UI patterns so the product feels trustworthy instead of overwhelming.

About me

I enjoy turning complex ideas into simple, reliable products.

I'm Donald, a full-stack developer working across AI tools, fintech, dashboards, design systems, and web or mobile apps. My best work sits where product thinking, system design, and thoughtful execution overlap.

I like working with teams that care about usability as much as architecture, especially when technically ambitious products need to feel calm and intuitive for real users.

Current interests

I'm especially interested in AI-native workflows, thoughtful developer tooling, and products that make messy real-world systems feel simpler and more trustworthy.
