I architect and build multi-tenant SaaS platforms for algorithmic crypto trading – not single bots, but the infrastructure that runs your customers' bots.
Who this is for:
– Teams launching a copy-trading service
– Trading SaaS startups (subscription-based access to strategies)
– Quant funds needing internal multi-user platforms
– DeFi projects with backend trading components
What I deliver in the base package:
Architecture audit and development plan. Not a $200 hello-world bot, but a technical document with: service decomposition, technology choices, per-tenant isolation strategy, security model for client API keys, scaling assumptions, risk analysis, time and budget estimate. Delivered as PDF and Notion doc.
Full implementation modules (add-ons):
– API Gateway and Orchestrator services
– Market Data service with WebSocket fan-out
– Per-user isolated worker processes
– CEX adapters: Binance, Bybit, OKX, Gate.io
– DEX adapters: Hyperliquid, dYdX, on-chain via RPC
– Client API key encryption at rest (split master-key model)
– Per-tenant network channel selection (proxy or dedicated IP)
– Frontend dashboard: React, Vite, Tailwind, realtime WebSocket
– Admin plane: structured logs viewer with cross-service correlation
– Production deployment: Linux, systemd, Caddy, monitoring
How I work:
1. We discuss scope on chat (in English).
2. NDA before sharing sensitive details – standard practice.
3. Architecture audit delivered first as a standalone deliverable.
4. Full implementation broken into milestones with fixed pricing.
5. Each milestone validated and paid before next one starts.
Portfolio reference:
Production multi-tenant trading platform. TypeScript end-to-end (pnpm monorepo). Four services: API Gateway, Orchestrator, Market Data, Worker. Per-user process isolation with isolated network channels. Client API keys encrypted at rest with split master-key. CEX integrations (Binance, Bybit, Gate.io) plus DEX (Asterdex). Realtime via native WebSocket + Redis pub/sub.
Stack:
TypeScript end-to-end. Backend: Node.js, Fastify, PostgreSQL, Redis. Frontend: React, Vite, Tailwind. Infra: Linux VPS, systemd, Caddy. Testing: Vitest with real DB integration.
Timeline:
Architecture audit: 2-4 days
Full implementation: 1-6 weeks depending on scope
Payment: USDT, USDC, ETH, DAI, or other stablecoins via LaborX escrow. NDA work welcome.
