At SignNow, I developed core features for an electronic signature service, including signing invite processing and document editing through the API. I also maintained legacy code and handled urgent issues reported by customers.
On a freelance CRM for chip-tuning services, I built the REST API and Filament 3 admin panel. I developed payments with Stripe, PayPal, and BitPay, and implemented real-time order chat using Laravel Reverb.
I also maintained and extended a car auction platform, adding PayPal payments and subscription plans with vouchers. I improved the sell-car flow and integrated external vehicle data APIs for lookup and valuation.
For a Telegram bot platform, I developed multi-step bot conversations and built the user cabinet and parts of the admin panel.
I'm interested in learning JavaScript as my next area of growth.
