Tech Lead - FotoStrana (06.2009 - 09.2018)
fotostrana.ru is a Russian social network with 1.5M DAU and 5M MAU.
Started here as an intern and made it to technical lead, proposing, designing and developing core features of the product, high load social services, and internal tools for developers. Since I worked here almost from a start-up company, I managed to build many things from scratch.
As a software engineer:
- Developed several developer and infrastructure tools: profiling php, mysql, memcached requests, application servers monitoring. Which helped other developers a lot.
- Had experience being a Release Engineer and developed release management and code deployment tools with release rollback (deploying PHP code from SVN to 100+ application servers in seconds, later migrated to Git).
- Designed and developed mailing system capable of sending over 10M emails daily with monitoring delivery rates, CTR, links checking.
- Developed tool for product managers to send promotion emails to our users filtered by different criteria.
- Developed PHP backend for notifications system, including API for in-house developers and external applications.
- Designed and developed standalone social apps for major social networks (Facebook, vk.com, odnoklassniki, mail.ru).
It was quite challenging because the backend was based on a single codebase and only the JS API differs, so it was very easy to maintain this apps.
- Did lots of refactoring and optimizations in different modules
- Developed features like:
- Importing photos and posts to user’s newsfeed from Facebook and vk.com.
- Signup with Facebook or vk.com account.
- User privacy system.
- Friends birthdays calendar with reminders.
As a tech lead:
- Managed and developed service “Daily photo contest”, which is on the main page of fotostrana.ru. It generates significant part of company’s revenue and huge amount of traffic.
- Interviewed and hired software developer candidates to my team
- Organized a training course for new developers. Trained and couched newbie developers, some of them are seniors now.
- Spoken at several conferences about software development (BitByte, #HPC, DEV {highload}) with a presentation about Fotostrana architecture.
Tech stack: PHP, JavaScript, MySQL, Memcached, Redis, MongoDB
