CHANGELOG FROM MY JOURNEY
Each role has shaped my skills and perspective as a developer. Here’s the journey of my professional experience.
Independent
Jan 2026 - PresentIndependent
Jan 2026 - PresentCarvix – Fuel Tracking Mobile Application(carvix.app · App Store)
- Engineered an end-to-end mobile application from concept to launch using React Native and Supabase, enabling users to log and monitor fuel expenditures either via camera receipt scanning (AI/OCR) or manual input; released on the App Store in May 2026.
- Architected a real-time dashboard displaying spending trends, average consumption, and profit/loss metrics. Integrated AI for receipt parsing and user feedback, Google Maps for real-time nearby station fuel pricing, and RevenueCat for in-app subscription lifecycle management.
- Achieved a 4.8/5 App Store rating (16 ratings), onboarding ~400 registered users with 150–200 monthly active users (MAU).
Freelance Web Projects
- Co-developed two tourist transfer booking web platforms for an Antalya-based tourism company, enabling visitors to choose vehicles, view routes, calculate transparent pricing, and schedule trips. Headed client communications and project management while actively contributing to frontend development.
- Configured and launched an e-commerce platform (carsimavm.com) from scratch on Ikas infrastructure and managed its operational setup.
Content Creation & Algorithmic Problem Solving
- Created software engineering and AI content on Instagram (@buildwithmami) detailing the development journey of Carvix, growing a community of 12K+ followers and generating over 2 million video views (700K+ on the Carvix build series).
- Sharpened algorithmic problem-solving by completing coding problems across LeetCode, HackerRank, and Codewars, publishing curated solutions on an open-source web platform (algorithm-with-mami).
Ayasofyazılım
Jan 2025 - Dec 2025Ayasofyazılım
Jan 2025 - Dec 2025UpWithCrowd – Equity Crowdfunding Platform
- Built the frontend of an equity crowdfunding platform from scratch within the team's monorepo architecture, collaborating closely with backend engineers and mastering the regulatory workflows of the crowdfunding sector.
- Deepened production expertise in Next.js and React while establishing reusable UI component architectures.
Unirefund – Global Tax-Free Shopping Platform(unirefund.com)
- Co-developed the React Native POS application used by retail merchants to generate tax-free invoices; integrated automated data fetching, OCR camera receipt scanning, and NFC ID/passport reading.
- Conducted intensive performance optimizations on resource-constrained POS hardware: reduced app startup time from 5–10s to 1–2s, and cut custom numpad input response time from 1.5–2s down to ~0.3s (e.g. migrating from TouchableOpacity to Pressable and fine-tuning render cycles).
- Developed major modules of the Next.js web application allowing travelers to access and manage tax-free refund claims via passport or ID verification.
- Engineered a rigorous 4-step identity verification flow to prevent fraud: MRZ ID/passport OCR scanning, NFC chip data extraction, FaceMatch between camera feed and document photograph, and interactive liveness checks (head turn and proximity prompts) to thwart photo-to-camera spoofing attempts.
- Created the official Unirefund landing page with Next.js and Strapi CMS, and contributed to the platform's mobile client.
- Authored foundational UI integration tests for form-intensive screens using Playwright.
