$400K+ earned on Upwork | 150+ jobs | 90+ five-star reviews | 4,500+ hours I'm Melissa Hong, founder of OMG Code, and I help businesses, entrepreneurs, and organizations turn ideas into working technology. My expertise spans Wix Velo, web development, mobile app development, APIs, AI integrations, automations, and custom software solutions. Whether you need to build something from scratch, integrate a third-party service, fix a complicated technical issue, or improve an existing application, I enjoy finding the solution. I'm a Top Rated Plus freelancer with a 100% Job Success Rate, a Wix Community Leader, and a Velo Certified Official Wix Legend Partner. Over the years, I've worked on everything from websites and e-commerce platforms to custom web applications, iOS and Android apps, backend systems, APIs, databases, automations, and AI-powered solutions. What I can help you with: • Wix & Velo development • Custom websites and web applications • iOS & Android mobile apps • API development and third-party integrations • AI integrations and prompt engineering • Backend development and serverless applications • Automations and business workflows • E-commerce and custom functionality • Database and application architecture • Troubleshooting and complex technical problems • Existing application improvements and maintenance One of the things I enjoy most about development is taking an idea that initially seems complicated and breaking it down into something that can actually be built. My path into technology wasn't traditional. I originally pursued medicine before making a career change into software development. That leap eventually led me to freelancing, building OMG Code, and working with clients around the world. I've also had the opportunity to speak for organizations including Wix, Upwork, Women Who Code, and Coding Dojo, and contribute as an instructor and blogger for Udacity. But the part of my career I'm most grateful for is the people I've met along the way. Many of my clients have returned for additional projects, referred me to others, and trusted me with increasingly complex ideas. If you have an idea you'd like to build, a technical problem you need solved, or a project that has become more complicated than expected, let's talk. I'd love to hear what you're working on and help you figure out the best way forward. :)

I turn messy data and manual, repetitive work into clean, automated systems and internal tools that save your team hours every week. You tell me the task, the file, and the result you want, and I hand it back working, documented, and easy to run yourself. I'm an independent consultant and developer with a Management Information Systems degree (Ateneo de Manila) and 10 years in product management, technical pre-sales, and software delivery across fintech and IT, including GCash / Globe Fintech (Mynt). Most recently I served as Project Director of iCASH, I-Remit's mobile e-wallet, leading it from concept to production launch. I've shipped real products end to end, so I focus on your goal, not just the task. WHAT I DO BEST - Excel & Google Sheets automation: dashboards, formulas (VLOOKUP/XLOOKUP, INDEX-MATCH, SUMIFS), pivot tables, and auto-calculating templates - Data cleaning, merging & de-duplication: turn messy multi-file data into one reliable, consistently formatted master sheet - Google Apps Script automation: auto-emails, scheduled triggers, PDF generation, and sheet-to-sheet sync - Custom Python scripts: process and convert data, organize files, collect data into clean CSVs, and automate manual work - Custom web & mobile apps for internal processes: dashboards and tools built in React/Next.js, Node.js, and PostgreSQL - Live crypto & stock trackers: watchlists, portfolio profit/loss, and trading journals (I am an active trader myself) - PDF / image to clean Excel or Word: typed and checked by hand, not just auto-converted - Website add-ons: contact forms, maps, chat buttons, and fast, mobile-friendly landing pages WHY CLIENTS WORK WITH ME - Business and technical background, so I translate a real-world need into a working solution - Clear communication and fast replies. I confirm anything unclear before I guess - Detail-oriented. Every entry, formula, and result is double-checked before delivery - Reliable and on time, always with a short how-it-works note so your team can run it without me ITIL Foundation certified. Available 30+ hours a week and responsive across time zones. Send me a message with what you need, and I'll reply with a clear plan and timeline.
