I love making sense of complex ideas and turning them into real software

I design and build full digital products that combine UX strategy, full-stack development, real-time capabilities, and AI integration, all in one seamless, expert-led process.

I build complex digital products from scratch or by evolving existing ones.

I bring clarity and structure to complex ideas, and turn them into usable, scalable, intelligent software

Internal tools and backoffice platforms

Solving Complexity Through UX, Engineering and AI

I turn product complexity into clarity, through UX, engineering and AI.

The digital products I work on aren't simple. They involve moving parts: real-time interaction, multi-role workflows, evolving logic, and sometimes, AI-powered features.

To make sense of that complexity and build something that actually works, I combine three core disciplines in one integrated process:

UX Design

Software Engineering

AI Integration

AI Integration approach

By combining these disciplines into a single, cohesive process, I reduce friction, cut overhead, and deliver high-impact solutions in a more cost-effective and time-efficient way — without sacrificing depth or quality.

These are not disconnected skills — they're the way I design clarity into complex software. Whether you're starting from scratch or evolving an existing system, I bring structure, focus, and execution to every stage.

How I Build Complex Products

From idea to product, one expert, one cohesive process

Here's how I typically approach complex digital products:

Throughout the process, I combine UX, engineering and AI to create cohesive, scalable and intelligent digital products, with clarity at every step.

1

Discovery & Product Framing

Discovery and Product Framing process

I align with your business goals, explore user needs, and define a shared understanding of what we're building, from scope to constraints.

2

UX Architecture & Interaction Design

UX Architecture and Interaction Design process

I map user flows, structure information, and design interactions using design thinking principles — validating early through lightweight prototyping and feedback loops.

3

Interface + Frontend Implementation

Interface and Frontend Implementation process

I translate high-fidelity design into modular, production-ready code — unifying design and development for better consistency, fewer errors, and faster iteration.

4

Full-Stack & Real-Time Development

Full-Stack and Real-Time Development process

I build scalable backends and dynamic frontends with real-time logic where needed — integrating product logic with UX to ensure everything works as a whole.

5

AI Integration

AI Integration process

When the product demands it, I design and implement AI-powered features: from multi-agent workflows and RAG pipelines to decision support, automation, and intelligent task handling. I ensure that every AI component aligns with user experience, business goals, and system architecture.

6

Evolution, Refinement & Support

Evolution, Refinement and Support process

Once launched, I help refine, scale and evolve the product — continuously improving based on feedback, performance, and new opportunities.

This integrated approach ensures that every step builds on the previous one, creating a cohesive product that's both technically sound and user-centered.

Selected Projects (coming soon)

I’m currently building a public portfolio with selected case studies that show how I approach product complexity through UX, full-stack architecture and AI. In the meantime, feel free to reach out — I’d be happy to walk you through relevant work.Where UX, AI, and Web Engineering Converge

Trusted by teams that build serious products

I’ve collaborated with companies and organizations across sectors — including education, logistics, compliance, public sector, and technology.

What clients say

Real feedback from teams and leaders I've worked with

"Working with Lucas is truly a pleasure. Even when unexpected issues or urgent situations arise, his technical expertise and professionalism shine through. His experience in maintenance and technical support is clear: instead of lengthy explanations, it's just a matter of agreeing on when to get things done. Without a doubt, he’s someone you can fully rely on."

Valentín Muro

CTO, Cenital

"Lucas was instrumental in building Eunoia Care, contributing as a UX designer, developer, and engineer while also guiding key decisions. His mix of technical expertise and user-centered thinking helped us create an app that is intuitive, reliable, and truly aligned with our mission."

Martín Bianchi

CEO, EunoiaCare

"Lucas was essential in our AI automation project, combining UX, engineering, and AI integration to cut processes from days to minutes. His strategic guidance, technical expertise, and user-centered vision made him an outstanding and trusted partner."

COO, CertiFlow

I build intelligent digital products

Where UX, AI, and engineering converge

Lucas Semelin

I design and build web-based software solutions with a strong focus on user experience and applied artificial intelligence.

With over 20 years of experience in software development and 8+ years in UX and product strategy, I bring a combination of technical expertise, strategic thinking, and holistic product vision. I specialize in creating robust, scalable systems that are usable, intelligent, and designed to evolve from day one.

I work independently with startups, companies, and organizations facing complex technological challenges — helping them modernize operations, automate workflows, or launch entirely new digital products.

My work is rooted in:

  • UX/UI design and product architecture
  • Full-stack development using Laravel & Vue.js ecosystems
  • AI integration: agent workflows, LLMs, RAG pipelines, and decision automation
  • Long-term evolution, technical maintenance, and continuous improvement

I've led the design and implementation of SaaS platforms, enterprise software, public sector tools, and AI-augmented systems used by tens of thousands of users.

In every project, I operate as a Digital Product Architect — aligning business goals with user experience and technical execution in one cohesive process.

I'm based in Argentina and work remotely with clients across the world — leading high-impact projects from concept to launch and beyond.
