Why it matters
Booking a master still often lives in DMs and WhatsApp: “free tomorrow?”, “in an hour?”, “oops, forgot to remind”. Clients get tired of typing. Masters get tired of answering. Slots vanish into chat silence.
This wasn’t a draft or a “book now” button. It needed a full marketplace: filtered catalog, map, client path, master SaaS cabinet, roles, platform admin, payments, notifications and production. Client — Victoria D. Budget — 230,000 ₽ (≈ $2,940). Timeline — 3 weeks.
How it works
Client opens slotty.of.by (web or Telegram Mini App) → catalog → filters / map → master → service → open slot → confirm. Booking code, Telegram + email reminders — no calls.
Masters run profile, portfolio, address, services, promos, schedule, requests and clients; Free or Pro plan.
Platform admin moderates masters, bookings, billing, bePaid payments, broadcasts and audit — the platform is operable now.
What’s inside
A large build, not a landing with a form. Frontend: React + TypeScript + Vite + Tailwind. Backend: Express API, PostgreSQL (88 migrations), JWT sessions. Production: two Railway services (web + api), domain slotty.of.by — we advised where to buy the domain, set up hosting, pointed DNS and shipped live. Plus Telegram Bot / Mini App, Google Auth, email (Resend), maps (Leaflet / OSM, optional Yandex), bePaid (BYN), Sentry, SEO prerender.
Client marketplace: 6 categories (manicure, barbers, brows/lashes, massage, fitness, tattoo). Catalog isn’t a flat card list — full search: all / popular / promos / new, text search, map with geo sort.
Filters: sort (recommended, popular, soonest, distance, rating, price ↑↓, reviews); date (today / tomorrow / week / weekend / exact day); time of day + hour slider; studio or at-home; duration; BYN price; rating from 4.5 / 4.7 / 4.9; review count; verified only; promos only; online booking only. Booking: date → slot → comment → reference photos → success with code SL-…. Client profile: appointments, favorites, notifications, settings, post-visit review.
Master cabinet is a separate SaaS: today / requests / schedule / services (catalog, prices, bundles, promos) / profile & portfolio / clients / reputation / billing / notifications (dozens of event types). 8-step onboarding: categories → profile → map address → services → trust → preview → plan. Plans: Free (limits) / Pro / 7-day trial — bePaid or manual transfer.
Platform admin: overview, requests (category changes, deletions, sponsorship, reports), support, system status, users, masters, services, bookings (incl. problem cancellations), billing & promo codes, bePaid payments, broadcasts, audit. Roles: client / master / platform_admin. Auth: email, Google, Telegram — phone or desktop.
Hard pieces that usually blow timelines: concurrent booking & slots, pending expiry, auto-complete, booking disputes; Free/Pro entitlements; notification job queue; multi-identity auth; server catalog with 20+ filter params and Pro boost in recommendations.
