Cover image for Color Before the Lines: reverse

Color Before the Lines: reverse coloring for iPad and iPhone. My own product, from concept to the App Store. The watercolor is already on the page; you add the lines, with a finger or Apple Pencil. I designed and built it in Swift: the calm, no-rules flow, the onboarding, the collection and the drawing canvas. Key product decisions: I prototyped three ways to generate backgrounds in code, then shipped hand-painted watercolors because they looked clearly better. I kept the tools to three, so nothing gets in the way of drawing. And it's one universal app, where the iPhone layout is designed for a fingertip, not shrunk from the iPad. Drawings stay on the device and analytics are anonymous.

Cover image for Virtual Assistant is a web

Virtual Assistant is a web application that allows users to intuitively and effectively complete an online application for assistance from the Westminster City Council. It is an app that uses a simple and intuitive UI to walk the applicant through the application process by providing step-by-step guidance. At the end of the application process, the applicant will be able to submit all the signed documents to the Local Government Pension Scheme Office for processing. Technical Implementation The software is written using Javascript and PHP. The Front-end part is made using Angular framework and the Back-end part is made using a custom made internal PHP framework. The Local Government Pension Scheme Office receives the signed documents via email in PDF format thus saving precious time that was spent assisting the applicants that used to go directly to the office to ask for guidance in filling the paper application form.

Shopify Developer | Rental, Booking & Custom Apps

Cover image for Ocelot is an open-source code

Ocelot is an open-source code intelligence platform I designed to help developers and teams understand complex codebases through AI-powered search and natural language queries. The system combines semantic retrieval, syntax-aware analysis, and dependency graphs to build a structured representation of a software project rather than treating source code as plain text. Ocelot analyzes classes, methods, dependencies, and relationships across the codebase, allowing users to ask questions about architecture, business logic, implementation details, and dependencies in natural language. Key capabilities include: Hybrid semantic and syntax-aware code search RAG-based question answering over source code Dependency graph generation Method and class-level indexing Incremental indexing for changed files Structured metadata extraction Support for backend and frontend codebases Java, Angular and TypeScript analysis Architecture and business-logic exploration through natural language I designed the architecture, indexing pipeline, retrieval strategy, dependency analysis, and AI interaction layer with a focus on making large codebases easier to navigate and understand.

Cover image for RentBase is a Shopify app

RentBase is a Shopify app I designed and developed to help merchants manage rental and booking workflows directly inside their store. The app handles complex rental logic such as availability, rental duration, daily and hourly pricing, scheduling rules, buffers, return dates, booking limits, product-specific settings, and checkout integration. I built the product end-to-end, including the merchant admin experience, storefront booking flow, Shopify integrations, backend logic, and ongoing production support. A major focus of the project was flexibility: merchants can configure rental behavior globally or per product without changing their existing Shopify store structure. Key features include: Rental and booking management Availability and date selection Daily and hourly pricing Custom rental packages Buffer times before and after rentals Same-day rentals Product-level and global configuration Multi-item rental cart flows Shopify checkout integration Theme integration and storefront customization Merchant-facing admin dashboard RentBase is currently used by real Shopify merchants, and I continue to develop new features, improve the UX, and solve real-world rental and booking requirements based on merchant feedback.

Cover image for I got tired of manually

I got tired of manually scraping platforms for automation gigs. It was taking me 20 hours a week just to find a couple of decent leads. So I built a custom n8n + Claude architecture to do it for me. I call it Vedetta. Instead of relying on basic keyword filters, I set up a Node.js backend that feeds raw data directly into a custom scoring model. Claude actually reads the job description and assigns an intent score from 1-10 (filtering out the low-budget clients right away). If a lead scores above a 7, n8n automatically drafts a tailored cold message and pings my Telegram. I get a notification on my phone. If the draft is solid, I hit approve and it gets sent. Zero hours spent sourcing. I only spend time talking to pre-qualified leads now. I just uploaded the full breakdown and dashboard UI in my portfolio here on Contra. If anyone's struggling with manual lead gen and wants to see how the n8n logic works under the hood, let me know in the comments.

The Technical Co‑founder You Can Hire

Cover image for Tilebit — Components and inspiration

Tilebit — Components and inspiration for Webflow, Figma, and Framer Tilebit is a platform of components and design inspiration for Webflow, Figma, and Framer, built for designer and YouTuber Arnau Ros (80k+ subscribers). The goal was to turn his experience and community into a real product, not just a showcase website. Arnau had the vision and the audience but no engineering background. I helped him plan the platform and choose the right tools for content, payments, access, and dynamic data, then built the integrations to make it all work inside Webflow. Key work: A structured content system on Webflow CMS to organize and update components and inspiration across platforms. Custom front-end JavaScript to fetch backend data and turn the CMS into a dynamic, interactive experience. Paddle integration for subscriptions, payments, and international tax handling. A custom Xano backend for dynamic data processing and API integrations. The result is a production-ready subscription platform that let Arnau monetize his content and grow Tilebit on solid technical foundations.

Cover image for I started out as a

I started out as a full-stack web developer (Angular, back in the day), working alongside several startups early on. That's where I learned the job is bigger than writing code: founders need someone who helps shape the product, not just build it. For about four years I moved into the Webflow world. And even there I wasn't just building websites: I used Wized and Xano to ship real web apps, and wrote JavaScript to add the interactivity those tools couldn't reach. That's also where I kept running into their limits. So now I'm back to development, working the way I do best: a technical partner who helps founders structure their product and prioritize what to build, then builds it with them. Scalable web apps from the ground up, and migrations off Lovable, Bolt, and other no-code tools when they start hitting walls with scale, security, costs, or lock-in. If that's where you are right now, let's connect. I'd genuinely love to hear what you're building.

Cover image for Unobravo — Online psychology platform
Unobravo

Unobravo — Online psychology platform Unobravo is Italy's leading online therapy platform, connecting patients with the right therapist. When I joined, the entire operation ran on Excel spreadsheets: matching, scheduling, and session tracking all done by hand. They needed to build their first real digital product. My role went beyond front-end development. I helped turn a manual process into a dual-sided product, contributing to how the work was structured, finding and coordinating designers and back-end developers, and shaping the dashboards that supported the company's early growth. Key work: A guided matching survey that pairs each patient with the most suitable therapist, replacing the manual Excel process. A psychologist dashboard for patient management, real-time chat, scheduling, reviews, and earnings. A patient dashboard for therapist profiles, chat, session purchasing, and billing. A shared calendar system linking therapist availability to patient booking, responsive from day one. The platform replaced Unobravo's spreadsheet operation and became the foundation for its growth: 400,000+ patients, 9,000+ therapists, 7 million sessions delivered, and a $17M Series A from Insight Partners.

Cover image for Cupis — Private offers platform

Cupis — Private offers platform for companies and employees Cupis is a closed benefits platform in Spain that connects companies, their verified employees, and brands. Companies offer perks to their teams, while brands reach a verified audience through private, non-public offers. The founders had a clear vision but no engineering team. I turned their idea into a production-ready web app with two sides: an admin dashboard for the Cupis team and a user area for verified employees. Key work: Private signup that validates employees by email domain against a company whitelist, without ever revealing which companies are clients. A curated coupon catalogue with shared or unique codes, including CSV imports of 50,000+ codes per offer, optimized to stay fast for both admins and employees. An operations dashboard to manage companies, access, coupons, visibility rules, and per-coupon analytics in one place. Self-service company access requests with admin approval. Built with Next.js, Supabase, Vercel, and Resend. The result is a production-ready platform that lets the team run the whole business independently, while employees get a simple way to access the offers available through their company.
