# Ruslan Khasanshin hu553in · senior software engineer — product & platform ## About I build products end to end and the platform foundations behind them — distributed systems, developer tooling, observability, and product UI. Over eight years, I’ve shipped software across insurance, travel, contact-center SaaS, creator tooling, and nonprofit infrastructure. I’m most useful when the requirements are incomplete, the system is unfinished, and someone has to turn that ambiguity into something reliable in production. I tend to go deep on products I care about: tracing edge cases, tightening the model, reducing operational ambiguity, and polishing things long after the happy path works. ## Work ### Resume [pdf](/resume.pdf) ### QIC digital hub senior backend engineer · since 2025 · [qic.digital](https://qic.digital) Joined while QIC’s new Go-based motor-insurance backend was still an incomplete pre-production rewrite. Helped take it through a phased production launch, built the observability foundation used across 25 services, and co-owned the backend launch of QIC Travel as part of a small backend team. ### Noveo senior java developer · 2021–2025 · [noveogroup.com](https://noveogroup.com) Built and operated five Java/Kotlin microservices for a cloud contact-center CRM. Reduced response time for a frequently called API from approximately 800 ms to 150 ms, added approximately 800–1,000 automated tests, and acted as tech lead for five engineers during the final 18 months. ### 7bits full-stack software engineer · 2017–2021 · [7bits.it](https://7bits.it) Built external and internal products with Java/Kotlin/Spring and React/TypeScript across the full development cycle. Led one project and taught introductory programming courses. ## Volunteer ### Nonprofit information platform volunteer lead software engineer · since 2024 I lead engineering for a production, location-aware nonprofit platform. I own the Django/DRF backend, deployment, and observability, contribute across the Next.js frontend, and work directly with users and a non-technical volunteer team to turn loosely defined needs into complete product changes. The work includes a timezone-aware scheduling engine, PostGIS-backed search, hierarchy-aware delegated administration, multilingual search, and a multi-stage performance program that reduced a key p99 from about 15 seconds to 500 ms. ## Skills - **product**: TypeScript, JavaScript, React, Next.js - **backend**: Node.js, Bun, Go, Java/Kotlin, Python, Django, gRPC/Protobuf - **data**: PostgreSQL, PostGIS, ClickHouse, Redis, Kafka - **platform**: OpenTelemetry, Prometheus, Grafana, Docker, Kubernetes - **ops**: GitLab CI, GitHub Actions, Ansible ## Projects ### voomy (independent product) A pre-launch bilingual creator platform for video, subscriptions, paid access, discovery, community, and moderation.

[medium en](https://medium.com/qicdigitalhub/technical-debt-isnt-just-legacy-how-we-re-reducing-divergence-across-go-services-6225e55b15c1) · [habr ru](https://habr.com/ru/articles/1056628) ### Designing a Real-World High-Scale Content Filtering System A conference talk on architecture, caching, horizontal scaling, observability, and failure handling. [youtube ru](https://www.youtube.com/watch?v=Xkidzosg02E) ## Interests 1. AI launches watched live, like season finales. 2. Open source that changes how I work. 3. Self-hosting, VPNs, and the hobbyist end of hacking. 4. Vibe coding sharp little utilities — most die young, and that’s fine. 5. Product design, especially the tiny details nobody asked me to polish. 6. [Borya the Welsh Corgi](/borya.jpg), voomy’s third founder. 7. A full-black Toyota Yaris and any excuse for a long drive. 8. Fashion — deeply loved, lazily practiced. 9. An unreasonable amount of movies, series, and no-name Twitch streamers — with my wife, always. ## Connect - GitHub: [hu553in](https://github.com/hu553in) - LinkedIn: [ruslan-khasanshin](https://www.linkedin.com/in/ruslan-khasanshin) - Telegram: [rkhasanshin](https://t.me/rkhasanshin) - Email: [r.m.khasanshin@gmail.com](mailto:r.m.khasanshin@gmail.com) ## Miscellany ### LinkedIn cover image (design tool) Use my template to make your own LinkedIn cover image.
