Fusion Second is a software development and product design studio in Beirut and Athens. We design and engineer custom web platforms, mobile apps, and enterprise business systems for tech startups betting their runway on the build, and for established organizations replacing what they can't afford to get wrong twice.
Senior engineers and designers across Beirut and Athens. Shipping since 2012 for travel, publishing, healthcare, fintech, e-commerce, film and culture, engineering, and consumer brands across Lebanon, the EU, the United States, and the Gulf.
No account managers, no offshore second team, no handoff after the proposal is signed. The people who scope your project are the people who build it. Eight in ten of our clients come back, and half of them have been with us for more than a decade.
Custom web platforms, websites, dashboards, and e-commerce. We design and engineer responsive, fast, accessible websites and web applications on architecture chosen for your traffic and your team.
Native and cross-platform iOS and Android development. Consumer apps, marketplaces, and field tools built in React Native or native code, from first wireframe to App Store and Google Play release.
Custom AI applications, model fine-tuning and machine-learning integration, built around a defined task and the data behind it. Our experience delivering AI-enabled products also means we'll tell you when AI isn't the right tool.
Senior technical leadership without a full-time hire: technical strategy, architecture review, delivery planning, technical-risk review and engineering-team guidance for founders and companies without an in-house CTO.
Technical SEO and Generative Engine Optimization: the site architecture, structured data, Core Web Vitals and content structure that help search engines and AI answer engines understand, surface and cite your brand.
Software audits, second opinions, and recovery work on builds that went wrong. Scoping, vendor assessment, and due diligence for teams deciding what to build or whether to rebuild.
CERTYTECH AI LIMITED
Maritime Credit Risk Assessment Platform
2025 – ongoing
B2B online platform, AI-powered, big data and machine learning
A shipping invoice holds 280 fields. Most credit teams read 4.
CERTY: we turned a single invoice into a live credit score
We built a pipeline extracting 280+ structured fields from shipping documents at 99% accuracy in under 40 seconds, then a scoring engine combining them with live AIS vessel data to generate continuously updated risk scores. We also designed and built the interface, voyage replay, portfolio dashboards, and marketing site.
Twister SAS
Travel Application
2017 – 2025
Enterprise architecture, B2C mobile application, proprietary algorithms, AI intelligence layer
We shipped machine learning in 2017. Nobody called it AI yet.
Twistr: we built the algorithm that strips a fare back to its real price
We engineered the full stack: data infrastructure processing millions of flights, a custom algorithm removing personalization factors that inflate ticket prices, and a React Native app presenting the result as one number. We also built a door-to-door advisory layer covering safety, baggage, meals, and ground transport.
Machine learning in production in 2017. The platform supported two seed rounds and grew to half a million users.
DeliciouSnacks LLC
E-commerce Platform
2014 – ongoing
Order management, user accounts, subscription management, and SEO/GEO-focused content.
The reason people buy was printed on the back of the bag.
Zesty Z: we rebuilt the storefront around a single nutrition claim
We rebuilt the Shopify storefront around fiber: a dedicated education hub, a recipe engine driving organic search, and product pages built around nutritional macros. We added custom Liquid sections, conversion tracking, and subscription functionality.
A full technical SEO overhaul covering architecture, metadata, and Core Web Vitals.
WALLETI LTD
Cryptocurrency Exchange Application
2024 – 2026
B2C fintech application, enterprise architecture, blockchain application
Hundreds of millions of people have cash and no bank account.
Walleti: we built a crypto on-ramp that never touches a bank
We built the full product: native iOS and Android apps, a crypto wallet, a redemption flow turning scratched card codes into ten supported coins in under 60 seconds, and a swap layer covering 160 assets. We integrated regulated custody and settlement partners, enabling the client to operate as a technology provider without holding funds, backed by a scalable enterprise architecture.
Released on both app stores in Q4 2025.
Arab Fund for Arts and Culture
Grant Management System & Custom Page Builder
2012 – ongoing
Nonprofit online platform, custom page builder
Most CMS work ends when the client wants a layout you didn't anticipate.
AFAC: we built a page builder, not a website
We built the Arab Fund for Arts and Culture a custom website-building system with hundreds of modular blocks their team can freely combine and publish without code or developer intervention. Every page, including those we never anticipated, runs through the same system.
We also integrated Formstack directly into the platform, bringing open calls and submissions into the website experience.
Two offices, one in-house team, working with clients across the Middle East and Europe.
