UX/UI Designer & Front-End Developer. I design interfaces and build them, from Figma to Production.
I'm a UX/UI Designer and Front-End Developer with 3+ years of experience designing and building digital products end-to-end. I work across the full process — user research, wireframes, and high-fidelity prototypes in Figma through to production-ready interfaces in React, WordPress, and WooCommerce.
What makes my work different is the combination. Most designers can't build. Most developers don't design. I do both, which means fewer handoff gaps, faster iterations, and products that actually match the intent behind the design.
I work directly with clients from day one: discovery sessions to understand your business and users, clear budget and timeline proposals, multiple design directions to choose from, and consistent communication until final delivery. No surprises, no intermediaries.
My background in QA testing at Practia Global — working on products for Credicoop and SanCor Seguros — sharpened my eye for usability, edge cases, and product quality that most designers miss.
Services I offer:
— UX/UI design: user flows, wireframes, design systems, and interactive prototypes
— Front-end development: React, HTML, CSS, JavaScript, Bootstrap
— WordPress and WooCommerce implementation
— Landing pages and responsive websites
— Full project management from kickoff to deployment
I've worked with startups, small businesses, and independent clients across different industries. Every project gets the same attention to detail regardless of size.

Work Terms
I work on both fixed-price and hourly projects depending on scope and complexity.
For fixed-price projects, I provide a detailed proposal with scope, deliverables, timeline, and total cost before starting. Payment is split into milestones: typically 50% upfront and 50% on final delivery, or divided into phases for larger projects.
For hourly engagements, I track time transparently and provide updates at regular intervals so there are no surprises on the invoice.
Every project starts with a discovery call or message exchange to define objectives, expectations, and constraints clearly. I don't start work without a mutual understanding of what's being built and what success looks like.
I'm available for async communication across time zones and typically respond within 24 hours. For ongoing projects, I provide regular progress updates and am open to scheduled check-ins via video call.
Revisions are included within the agreed scope. Out-of-scope requests are quoted separately and agreed upon before execution.
I take quality seriously: before any delivery, I test across devices and browsers, validate usability, and make sure the final product matches what was designed.
