I am a professional mobile app developer specializing in building high-quality custom applications tailored to client requirements. I can develop complete apps with advanced features, including a full admin panel and seamless user experience. I provide end-to-end support — from development to Play Store publishing and monetization strategies — ensuring clients understand every step of the process. You will receive full ownership of the app along with complete guidance and long-term support. My focus is on delivering reliable, scalable, and premium-quality solutions that exceed client expectations.

I build complete, production applications. Not prototypes, not templates. Most recently I architected and shipped Bailar, a dance-class marketplace running on iOS, Android, and web. Solo, in five months. It has native modules, Stripe payments, real-time booking with capacity caps and waitlists, push notifications, English/Spanish localization, over-the-air update infrastructure, and more than 1,300 database migrations behind it. It is live in the App Store and on Google Play. I mention the scale because it tells you the thing that actually matters when you hire a developer: I have shipped the boring, hard parts. App Store review. Payment edge cases. Migration rollbacks. Auth lifecycle. The work that separates a demo from a product. Before this I spent five years in enterprise consulting at RSM, so I can also read a business process, tell you which half of it should be software, and talk to your stakeholders without a translator. How I work, and why it is different from most listings you will read here: 1. FLAT PRICE, NOT AN HOURLY METER. You get a fixed number and a fixed scope before I start. No surprise invoices, and no incentive for me to work slowly. 2. YOU OWN EVERYTHING FROM DAY ONE. Your GitHub, your Supabase project, your Stripe account, your Apple and Google developer accounts. I work inside your accounts, not mine. If we stop working together tomorrow you lose nothing and you are not hostage to me. 3. THE HANDOFF. Every build ships with an AI-agent maintenance environment configured for your specific codebase: documentation, guardrails, and tooling so your team or a low-cost contractor can keep changing the product after I am gone. Most agencies sell a retainer because the code is only legible to them. I would rather sell you the next build than rent you access to the last one. Typical engagements: - Fixed-scope web builds, 1,500 to 3,000 - Cross-platform mobile apps for iOS, Android and web, 3,500 to 8,500 - AI assistants grounded in your own data such as menus, manuals, policies or catalogs, 1,800 to 5,000 - Internal ops dashboards and back-office portals, 2,500 to 6,500 Stack: TypeScript, React, React Native and Expo, Next.js, Supabase and Postgres, Stripe, Node, and the Anthropic and OpenAI APIs. If you have a scope, send it and I will give you a flat number and a delivery date. If you have a problem and no scope yet, tell me the problem. The first conversation is free and I will tell you honestly if software is the wrong answer.

I’m a Senior Product Designer with 6+ years of experience designing high-traffic, data-heavy mobile products across fintech, betting, and trading platforms. I specialize in mobile UX for complex, regulated environments where speed, accuracy, and clarity directly impact revenue and user trust. My focus is on simplifying complex user flows, reducing critical user errors, and increasing engagement through data-informed UX decisions. Recent work includes: • Improving engagement by 20% and reducing critical user errors by 26% on a large-scale sports betting platform • Increasing 30+ day user retention from 14% to 26% for a cryptocurrency trading product • Designing and scaling mobile UX solutions for a US-based startup as an ongoing freelance partner I work closely with product managers, engineers, and founders to translate business goals into clear, testable UX solutions — from discovery and flow design to high-fidelity UI and developer handoff. If you’re building a mobile product with complex flows, real-time data, or high-stakes interactions, I can help you design experiences that perform reliably at scale. Portfolio: msarslandesign.com

I rebuild Google Ads accounts for ecommerce brands where tracking is broken, bidding targets the wrong signal, and ROAS has stalled. 🏆 𝟮𝟬𝟮𝟱 𝗔𝗴𝗲𝗻𝗰𝘆 𝗼𝗳 𝘁𝗵𝗲 𝗬𝗲𝗮𝗿 for Ecommerce Development in Greece - Netstudio, where I lead Google Ads 🎯 𝗚𝗼𝗼𝗴𝗹𝗲 𝗔𝗱𝗪𝗼𝗿𝗱𝘀 𝗤𝘂𝗮𝗹𝗶𝗳𝗶𝗲𝗱 𝗜𝗻𝗱𝗶𝘃𝗶𝗱𝘂𝗮𝗹 + 𝗚𝗼𝗼𝗴𝗹𝗲 𝗣𝗿𝗲𝗺𝗶𝗲𝗿 𝗣𝗮𝗿𝘁𝗻𝗲𝗿 + 𝗜𝗦𝗢 𝟮𝟳𝟬𝟬𝟭 certified 📊 Dozens of Google Ads accounts built and managed end-to-end since 𝟮𝟬𝟬𝟴 📈 Client NPS 𝟲𝟳 - average client retention 𝟭𝟬-𝟭𝟱 𝘆𝗲𝗮𝗿𝘀 💼 𝟱𝟱-person senior EU team behind every Google Ads engagement: dev, CRO, and analytics at one desk "Google Ads structure rebuilt for our trade portal from scratch - B2B and B2C bidding separated at campaign and conversion-action level from day one. We finally have clean data showing which Google Ads channel drives distributors versus retail consumers." - Enterprise FMCG client, Greece (paraphrased) Most Google Ads accounts I inherit fail the same three diagnostics: broken conversion tracking, bidding to the wrong signal, and a landing page that destroys Quality Score. I rebuild Google Ads accounts from the campaign structure up - search campaigns, Google Shopping, and Performance Max each given a separate role, with first-party conversion tracking that survives iOS, GDPR consent, and cookie loss. Google Ads results come from the system - not from smart match types applied to a broken foundation. I fix the foundation before I touch the bid strategy. 𝗙𝗹𝗮𝗴𝘀𝗵𝗶𝗽 Google Ads 𝗘𝗻𝗴𝗮𝗴𝗲𝗺𝗲𝗻𝘁𝘀: 🌟 𝗠𝘂𝗹𝘁𝗶-𝘀𝘁𝗼𝗿𝗲 𝗳𝗮𝘀𝗵𝗶𝗼𝗻 (𝗚𝗿𝗲𝗲𝗰𝗲): Google Ads scaled across 𝟭𝟱 storefronts under one consolidated MCC post-replatform. ROAS held during 𝟯𝘅 spend lift. 🌟 𝗘𝗻𝘁𝗲𝗿𝗽𝗿𝗶𝘀𝗲 𝗷𝗲𝘄𝗲𝗹𝗿𝘆 (𝗔𝘂𝘀𝘁𝗿𝗮𝗹𝗶𝗮): Google Ads and Google Shopping rebuild on 𝟱𝟬𝟬𝗞+ SKU catalogue. Custom labels for margin-tier bidding. Server-side conversion tracking. 🌟 𝗕𝟮𝗕 𝗱𝗮𝗶𝗿𝘆 𝗙𝗠𝗖𝗚 (𝗚𝗿𝗲𝗲𝗰𝗲): Google Ads and landing page architecture for authenticated trade-portal lead capture. B2B and B2C bidding separated from day one. 🌟 𝗖𝗮𝗿 𝗿𝗲𝗻𝘁𝗮𝗹 (𝗖𝗼𝗿𝗳𝘂): Google Ads multilingual campaigns in 𝟱 languages. Fleet grew from 𝟭𝟬 to 𝟯𝟬𝟬 vehicles. 𝟭,𝟴𝟬𝟬+ annual bookings. 🌟 𝗠𝘂𝗹𝘁𝗶-𝗹𝗮𝗻𝗴𝘂𝗮𝗴𝗲 𝗽𝘂𝗯𝗹𝗶𝘀𝗵𝗶𝗻𝗴 (𝟮𝟲 𝘀𝗶𝘁𝗲𝘀): Google Ads mirrored across 𝟮𝟲 storefronts with country and language attribution wired to GA4. 𝗪𝗵𝗮𝘁 𝗜 𝗗𝗲𝗹𝗶𝘃𝗲𝗿: 🔹 Google Ads Account 𝗥𝗲𝗯𝘂𝗶𝗹𝗱𝘀 Google Ads campaign structure aligned to margin tier and business objective. Google Shopping, Search, Performance Max, and Demand Gen each get a defined role - not stacked. A clean Google Ads account architecture earns algorithm trust from week one. Google Shopping feed engineering included as standard on ecommerce Google Ads rebuilds. 🔹 Google Ads Conversion Tracking Server-side GA4 + Google Ads conversion tagging that survives cookie loss, consent banners, and iOS restrictions. ROAS you can trust - not guessed from broken attribution. Same engineers who build the ecommerce storefront wire the Google Ads tracking. 🔹 Google Shopping 𝗙𝗲𝗲𝗱 𝗘𝗻𝗴𝗶𝗻𝗲𝗲𝗿𝗶𝗻𝗴 Title structure, attribute coverage, Google Merchant Center health, custom labels for margin-tier bid segmentation. A clean Google Shopping product feed is 𝟯𝟬% of the Google Ads result - and most ecommerce stores have broken feeds. 🔹 Google Ads Audit + 𝗗𝗶𝗮𝗴𝗻𝗼𝘀𝘁𝗶𝗰𝘀 Every Google Ads engagement starts with a written audit covering account structure, conversion signal quality, Google Shopping feed coverage, and landing page Quality Score. No spend moved before the foundation is verified. 🔹 𝗟𝗮𝗻𝗱𝗶𝗻𝗴 𝗣𝗮𝗴𝗲 𝗖𝗥𝗢 for Google Ads Page speed, message match, and form architecture aligned to Google Ads campaign intent. Quality Score climbs, Google Ads CPCs drop, ecommerce conversion rate improves. 𝗪𝗵𝗼 𝗜 𝗪𝗼𝗿𝗸 𝗪𝗶𝘁𝗵: 💼 I run Google Ads for ecommerce brands with monthly ad spend between 5K and 100K, where the storefront is core to revenue and paid acquisition is the growth engine. If you spend under 2K/month or need a quick keyword list, I am not the right call - I work on accounts where the architecture matters and the margin is large enough to optimise. 𝗠𝘆 𝗣𝗿𝗼𝗰𝗲𝘀𝘀: 🔄 𝟭. Week 1 Google Ads Audit - account structure, conversion tracking, Google Shopping feed, landing pages, attribution. Written diagnosis with a go / no-go. 🔄 𝟮. Week 2 Fixes - tracking and feed repaired before structural changes. No bid moves until signal is clean. 🔄 𝟯. Weeks 3-8 Google Ads Rebuild - new campaign architecture, test framework, weekly performance reviews. 🔄 𝟰. Ongoing Google Ads Management - monthly optimisation, quarterly creative and feed refresh. Ready to fix your Google Ads ROAS? Send the account spend, current ROAS, and main product categories. If Google Ads is not the right channel for your business, I will say so on the first call.
