  • Project mention: Building in Public: Leveraging Tublian's AI Copilot for My Open Source Contributions | | 2024-02-12

    Contributing to Apache Airflow's open-source project immersed me in collaborative coding. Experienced maintainers rigorously reviewed my contributions, providing constructive feedback. This ongoing dialogue refined the codebase and honed my understanding of best practices.

  • airbyte

    The leading data integration platform for ETL / ELT data pipelines from APIs, databases & files to data warehouses, data lakes & data lakehouses. Both self-hosted and Cloud-hosted.

  • Project mention: Launch HN: Bracket (YC W22) – Two-Way Sync Between Salesforce and Postgres | | 2023-12-12

    I'l also give a shout-out to Airbyte (, with which I've had some limited success with integrating Salesforce to a local database. The particular pull for Airbyte is that we can self-host the open source version, rather than pay Fivetran a significant sum to do this for us.

    It's an immature tool, so I don't yet know that I can claim we've spent _less_ than Fivetran on the additional engineering and ops time, but it feels like it has potential to do so once stabilized.

  • WorkOS

    The modern identity platform for B2B SaaS. The APIs are flexible and easy-to-use, supporting authentication, user identity, and complex enterprise features like SSO and SCIM provisioning.

  • Project mention: Read files from s3 using Pandas/s3fs or AWS Data Wrangler? | /r/dataengineering | 2023-12-06

    I had no problem with awswrangler ( and it supports reading and writing partitions which was really helpful and a few other optimizations that made it a great tool

  • ethereum-etl

    Python scripts for ETL (extract, transform and load) jobs for Ethereum blocks, transactions, ERC20 / ERC721 tokens, transfers, receipts, logs, contracts, internal transactions. Data is available in Google BigQuery

  • Project mention: Blockchain transactions decoding: making wallet activity understandable | | 2023-10-27

    Event is a log entity which EVM smart contracts can emit during transaction execution. Events are very good at signalling that an some action has taken place on-chain. Applications can subscribe and listen to events to trigger some off-chain logic or they can index, transform and store events in some off-chain storage (look at The Graph protocol or Ethereum ETL).

  • mara-pipelines

    A lightweight opinionated ETL framework, halfway between plain scripts and Apache Airflow

  • InfluxDB

    Power Real-Time Data Analytics at Scale. Get real-time insights from all types of time series data with InfluxDB. Ingest, query, and analyze billions of data points in real-time with unbounded cardinality.
