Hi, I'm Alexandru Ionescu
I build web apps that help businesses work better
15 years of corporate training taught me how teams actually work. Now I turn that understanding into tools people love using.
What clients & users say
“We switched from paper-based exercises to Dilemix mid-program. Engagement went through the roof — participants were actually talking to each other instead of staring at handouts. We haven't gone back since.”
Erik van der Berg
Senior Training Consultant, Global L&D Consultancy
“Alexandru built our workshop app in 6 weeks. We've run it at over 150 events now and haven't had a single crash. Participants always ask how they can use it again at home.”
Stefania Marian
Founder, Scent Studio
“I was skeptical about replacing our in-person simulation materials with a digital tool. After the first session, our facilitators refused to go back to paper. Prep time alone saved us half a day per workshop.”
Thomas Richter
Corporate Trainer, Leadership Training Firm
“We run Dilemix sessions with 60-80 people at a time across three languages. The platform handles it without breaking a sweat. Our clients think we built it ourselves — that's how well the white-labeling works.”
Maria Santos
Learning & Development Lead, International Training Company
Services
What I can help with
I focus on web applications that serve a real purpose — tools that people use every day, not projects that look good in a pitch deck and collect dust.
Interactive Web Applications
Real-time, multiplayer, and data-driven apps built with modern frameworks. The kind of tools that users actually want to come back to.
Custom Business Tools
Client-facing platforms and internal tools designed around how your business actually operates — not how a template thinks it should.
Landing Pages & Marketing Sites
Fast, responsive, and built to convert. Clean code, proper SEO, and performance that makes a difference.
Training & E-Learning Apps
Built by someone who's facilitated hundreds of training sessions. I know what trainers need because I've been one for 15 years.
AI-Powered Apps
Smart assistants, content generation, and AI-driven workflows built directly into your app. Not bolted-on gimmicks — real AI that solves real problems.
API Integrations & Automation
Connecting your tools together — Supabase, payment providers, AI APIs, CRMs, and more. Workflows that run themselves so your team doesn't have to.

About
I've been in your shoes. That's why my apps actually work.
Before I started building apps, I spent 15+ years delivering corporate training programs and coaching. I've worked inside companies, facilitated workshops with leadership teams, and designed learning experiences that actually change behavior.
That background is the reason my apps work — I understand how people learn, how teams operate, and what makes someone actually want to use a tool. My product Dilemix is a multiplayer behavioral simulation platform used by training companies worldwide. I designed it, built it, and ship updates every week.
When you work with me, you get someone who actually listens, understands your problem, and builds the right thing — not just the first thing that comes to mind.
