I will integrate crypto exchange and market data api into your app
Full Stack Developer AI Apps and APIs
I build and ship production apps — live web apps, a Shopify app, real backends and APIs.
I'm strongest where AI-generated code breaks: the last 30% where auth fails, deploys won't work, and half-buil...
About this Gig
Most API gigs say they integrate any API. Exchange and market data APIs are not any API.
Rate limits, HMAC request signing, WebSocket reconnects, candle gaps, and timestamp drift break in production, not in testing.
WHAT I DO
Exchange REST + WebSocket integration (Binance, OKX, Bybit, Coinbase, Kraken)
Live price feeds, OHLCV candles, order book and trade streams
TradingView webhook to your backend to exchange order
Trading bot API layer: auth, signing, order placement, error handling
Stock and forex market data APIs
Reconnect logic, rate limit queueing, failover
PROOF
I built and run a live market data app: real-time crypto, stock, and forex prices; TradingView charts; price alerts; email; and web push. Portfolio link is on my profile.
Its crypto feed moved across three exchanges in production: Binance, which dropped after a US geo-block (HTTP 451); then Kraken; then OKX with a live websocket trade stream. Most gigs have never had to deal with that.
Message me before ordering with your exchange and what you need. If it is out of scope, I will tell you honestly.

FAQ
Which exchanges do you work with?
Binance, OKX, Bybit, Coinbase and Kraken are the ones I use most, but I can work with any exchange or data provider that has public documentation. Message me with your exchange before ordering and I will confirm it is doable.
Do you need my API keys?
For price and market data, no keys are needed. For placing orders. I need a key with trading enabled and withdrawal disabled. You can revoke it the moment delivery is done. I never need your exchange account password.
Can you build my whole trading bot?
The strategy logic stays yours. I build the layer that talks to the exchange: authentication, request signing, order placement, WebSocket streams, error handling, and reconnects. That is the part that usually breaks.
I built my app with Lovable, Bolt or v0. Can you add a real feed to it?
Yes. A lot of my work is adding a real backend and live data to AI-generated apps. Send me the repo or the live link and tell me which exchange you want, and I will tell you what it needs.
What if it breaks after delivery?
I test against the live API, not mock data, so what I deliver is what runs in production. If something inside the delivered scope breaks, I fix it. If the exchange itself changes its API later, that is a new job, and I will quote it fairly.
