My professional journey in frontend development
├─│
📁Full-Stack Developer
@ Happy Delivery / Happy Go • Remote
[March 2026 – Present]
Delivery & logistics platform built as a Go microservice monorepo with Next.js CRM frontends and a Flutter mobile app for card/SIM warehouse and courier meeting workflows.
$ cat achievements.txt
❯Reworked the authentication system (NextAuth + Keycloak replacing Traefik forward-auth), migrated the CRM’s map infrastructure off Yandex Maps v3, and overhauled the DevOps toolchain (Makefile, Ansible, Portainer)
❯Deployed and localized a corporate LMS (Frappe Learning), built referral landing pages (Bitrix24) and a landing page with complex Framer Motion animations, and set up Husky/ESLint/Prettier as the team’s commit workflow
❯Architected and built a new CRM system for card/SIM warehouse lifecycle management (transfers, audits, partner integrations) from scratch, full ownership from architecture to production
❯Led the migration of the main CRM from REST to Connect-RPC (protobuf-es v2): migrated 10+ feature areas (users, partners, products, statuses, scenarios, zones/sub-zones, worktime, order and schedule-change verification queues); established the reusable pattern of server/browser Connect clients, JS_STRING int64 handling, and a cached-options registry; deleted the legacy REST handlers in the Go gateway; found and fixed several latent production bugs along the way
❯Built a delivery-zones map feature (geo-service + CRM): a new public gRPC endpoint computing each zone’s map position as the PostGIS centroid of its sub-zone polygons; rendered zones as a native MapLibre WebGL circle layer replacing laggy DOM markers; added server-side polygon overlap validation (ST_Intersects/ST_Touches); diagnosed and fixed a production 500 caused by mixed-SRID PostGIS geometry
❯Built region management (name + ISO code) end-to-end: geo-service model/repository/5 gRPC methods, plus the CRM menu, table, and form dialog
❯Wired Dadata’s region parsing into a region-id lookup end-to-end: a DB migration and proto field on orders, plus a delivery-worker update to set the region during address parsing
❯Reworked the card-binding meeting flow across the full stack (proto → backend service → backend gateway → CRM verification form → Flutter mobile app)
❯Cleaned up technical debt in the Go backend: renamed Get→List methods where they returned a list of entities, extracted repeated literals into pkg/constants, and consolidated repositories onto a single existing List method instead of duplicated logic
❯Analyzed the CRM’s highest-traffic gRPC endpoints and identified which ones had low enough data-change frequency to cache; designed and implemented backend-side caching, complemented with TanStack Query caching on the frontend, cutting redundant round-trips to the backend
