shipping consistentlyI have been actively developing software since 2022, focusing on building modern web applications and specialized software interfaces. Through Software Forge, I enjoy collaborating with teams to solve technical problems and build high-quality products.
Production Electron-based CNC control application. Built UI features and device configuration flows for Raspberry Pi (ARM64), improved hardware state sync via G-code serial communication, handled ESP firmware versioning, and packaged Linux ARM64 (.deb) releases.
Web application where users compare car insurance prices, get quotes, explore insurance products, and make purchases. Developed as part of a team.
Real-time cafe/restaurant order management (POS) with live sync between cashier and customer-facing displays via Socket.io over a custom Node.js server. Built multi-cart, split-bill, cash/card payments, and Excel-export reporting on Supabase (PostgreSQL) with RLS. Packaged as a cross-platform desktop app via Electron with automated GitHub Actions releases. Integrated the Trendyol Marketplace API to surface incoming marketplace orders as real-time in-app notifications. Paired with a serverless analyzer that mines the POS sales data and sends weekly/monthly Gemini-generated profit strategies to Telegram on a Vercel Cron schedule.
AI-native mobile habit tracker on the App Store. Integrated LLMs for personalized, context-aware behavioral insights — managed the full product lifecycle from core architecture to ASO.
Barcode-scanning beverage info app on the App Store. Scan any drink to view ingredients, sugar, minerals, and safety details from an open food-data API. Implemented an auto-renewing subscription paywall and guest mode.
iOS accountability & habit app on the App Store. Users back their goals with a virtual "lives" system — start with 3 lives, lose one per failed goal, earn them back via daily check-ins (5 streak = +1) or in-app purchase. Built solo end-to-end with a local-first architecture (no backend/login, all data on-device via Zustand + AsyncStorage), a client-side evaluation engine that auto-computes success/failure on launch, RevenueCat consumable IAP, and Guideline 3.2.2-compliant virtual currency.
Embedded Shopify SaaS built to replace Shopify's sunsetting Stocky app. Multi-tenant purchase-order (PO) management with automatic inventory sync to Shopify via the Admin GraphQL API — using idempotent, concurrency-safe mutations. Includes tiered subscription billing (Shopify Billing API), CSV migration from Stocky, low-stock alerts, and server-side barcode label PDF generation. In production on Vercel + Neon.
Modern, SEO-focused website showcasing dietitian services, built with a strong emphasis on performance and accessibility.
