take i2c and analog sensor together

[Raylpast]

i make a project to take a raw ppg's data with infrared led that take from max30105 sensor and green's led data from heart rate pulse sensor. I take data simultaneously with frequency sampling 100 Hz in different esp32 microcontroller. When i take data for 1 minute, i get 2900 data from max30105 and 5790 data from heart rate pulse sensor. This different sample data from max30105 and pulse sensor making the data difficult to process. Can you help me how to fix this?
This is my analog program
#include <WiFi.h>
#include <WiFiClientSecure.h>
#include <PubSubClient.h>

const char* ssid = "xxxx";
const char* password = "vvvv";

const char* mqtt_server = "a20555bc.s1.eu.hivemq.cloud";
const int mqtt_port = 8883;
const char* mqtt_user = "pulupulu";
const char* mqtt_pass = "12345";

WiFiClientSecure wifiClient;
PubSubClient client(wifiClient);

// Buffer untuk 10 data
int buffer[10];
int bufferIndex = 0;

void setup_wifi() {
WiFi.begin(ssid, password);
while (WiFi.status() != WL_CONNECTED) {
delay(500);
Serial.print(".");
}
Serial.println("\nWiFi connected");
}

void reconnect() {
while (!client.connected()) {
Serial.print("Attempting MQTT connection...");
if (client.connect("ESP32_Analog", mqtt_user, mqtt_pass)) {
Serial.println("connected");
} else {
Serial.print("failed, rc=");
Serial.print(client.state());
Serial.println(" retrying in 5 seconds...");
delay(5000);
}
}
}

void setup() {
Serial.begin(115200);
setup_wifi();

wifiClient.setInsecure(); // Tanpa SSL sertifikat manual
client.setServer(mqtt_server, mqtt_port);
}

void loop() {
if (!client.connected()) {
reconnect();
}
client.loop();

// Baca sensor analog
int value = analogRead(32);
buffer[bufferIndex] = value;
bufferIndex++;

// Jika sudah 10 data, kirim sekaligus
if (bufferIndex >= 10) {
String payload = "[";
for (int i = 0; i < 10; i++) {
payload += String(buffer);
if (i < 9) payload += ","; // Tambah koma kecuali terakhir
}
payload += "]";

// Kirim ke HiveMQ
client.publish("sensor/analog", payload.c_str());

bufferIndex = 0; // Reset buffer
