Developer with Bitquery and Tradingview experience needed

We are currently in the midst of integrating tradingview (crypto) charts into our site. We have set up a UDF server which fetches live trading data from Bitquery and provides the chart with OHLC data. The data provided from our udf server is sometimes incorrect, and also the loading time is quite long. Looking for someone who already has a solid amount of experience with these technologies to get this service past the finish line.
