Who am I?

Hi, I am Alihan SARAÇ /ʌlɪhʌn sʌrʌ"tʃ"/ 👋

Born and raised in the hometown of 🐈's, İstanbul in Türkiye. I'm a curious candidate for computer engineer who loves coding and computers. In order to master computer science philosophies. I am currently improving myself in the fields of electronics, databases, web software, mobile software, desktop software, internet of things, robotics, embedded software and I am learning more and more every day. learning different disciplines by getting to know more people, so I support both university and non-university communities as an administrator or active member.

Coding and sharing my own packages/applications is one of my greatest pleasures as I enjoy developing in JavaScript, C, Linux and open source ecosystem. On full time job i use JAVA 🙃

My Experiences

List all projects

• Full stack developer @Provence Pazarlama Danışmanlık

  • February 2025 - now
  • I rebuilt eczanesitesi.com, a PHP-based news site for pharmacists, to improve UX, speed, and SEO, and to make it easier to maintain with modern technologies. The project was redeveloped using Next.js and Java. I modernized the user interface, added performance-friendly animations and flows, simplified the admin panel, and automated image editing tasks previously done manually by moderators. As a result, site performance improved by 60%, and more than 20,000 data entries were migrated flawlessly between systems.
  • I designed and developed from scratch the platforms dermokozmetikokulu.com, otcokulu.com, and aromaterapiokulu.com, which provide training in dermocosmetics, OTC, and aromatherapy. These sites include blogs, role-based and subscription-based content access, and full content, user, and access management panels. I managed the entire development, deployment, and maintenance lifecycle, using React, MUI, Java, Hibernate, and Spring Boot. I ensured the three platforms shared a common interface skeleton while maintaining unique themes, content, and workflows. I integrated Iyzico for one-time and subscription payments, Paraşüt for e-invoicing, and automated reminders and special-case email workflows. I also established backup, monitoring, and alert infrastructures, making security vulnerabilities trackable, and improved both SEO and user analytics.

• Full stack developer @ Dermoino / Pharmaino

  • June 2023 - now
  • Dermoino is the digital medical assistant for pharmacies. Patients solve the test about their skin problems by scanning the pharmacy's QR code, and then their answers are analyzed, ingredient and product recommendations are made to the pharmacist, and an anamnesis note is prepared. Pharmacists can analyze patients arrival times, skin type density in their region, pharmacists patient care and product sales statistics, and site managers can do these across the pharmacy, region or country.
  • I developed website and desktop application using Vue 3, Tauri, SASS and Bootstrap. In addition to creating and updating products, pharmacies and sales person, listing and deleting operations with advanced filters, real-time data flow, detailed charting of analyses, tracking of read receipts of tests, creation and printing of QR advertising banners for pharmacies, excel import/export, localization, responsive email template(welcome, forgot password, etc.) features are among the things i do.
  • I took care to make efficient improvements in terms of UI/UX and resource usage on the pages that patients can access using QR codes.
  • I developed REST API with Node.js, MongoDB, Docker, AWS S3, bash script(backup, migration), mail client.All improvements have been made for the features mentioned above. The API is set to log every transaction and take regular database backups and is run on a VPS.
