Hire the Best Technical Writers

Most data pipelines don’t fail because of code. They fail because they weren't built for scale. With 5+ years of experience engineering data systems at companies like Danone and Zurich, I help businesses transform fragile prototypes into resilient, production-grade infrastructure. I don’t just move data; I build the "Source of Truth" that leadership and AI systems actually trust. ➔ Productionizing AI Pipelines: Hardening Python prototypes into scalable RAG and LLM infrastructures (Azure). ➔ Infrastructure-as-Code: Building automated, modular ETL/ELT pipelines that don't require daily manual fixes. ➔ The "One-Source" Dashboard: Integrating messy data from APIs, SaaS (Shopify, HubSpot), and databases into clean Snowflake/BigQuery layers. ➔ Performance Recovery: Optimizing slow SQL queries and high-cost cloud warehouses to save you thousands in monthly spend. ➔ Technical Writing for Data & AI Teams: Creating product documentation, implementation guides, architecture documentation, data dictionaries, knowledge bases, and thought leadership content that makes complex systems easier to understand and adopt. 🛠 Tech Stack Languages: Python (FastAPI, Pandas, PySpark), SQL Data Engineering: ETL/ELT Pipelines, Data Warehousing, Data Modeling, Data Quality, Data Governance Cloud & Warehousing: Snowflake, BigQuery, Databricks, Azure Data Factory, Azure Data Lake, AWS (S3, Athena, Glue) Orchestration & Transformation: Apache Airflow, dbt Analytics & BI: Tableau, Power BI Development & Collaboration: Git, GitHub, VS Code Data Ops: API Integrations, Data Validation, Workflow Automation Technical Writing: Product Documentation, API Documentation, User Guides, Knowledge Bases, Data Dictionaries, Technical Blog Content ✅ Why Me? 5+ Years Experience: I've seen what breaks at the enterprise level and how to prevent it in your startup. Hands-On Builder & Technical Writer: I can both build the system and explain it clearly to engineers, stakeholders, and customers. Speed over Perfection: I focus on shipping high-impact systems that drive revenue, not just technical documentation. Transparent Communication: You get regular updates and a partner who challenges requirements to find better solutions. Ready to clean up your data debt?

Seven years in product, four of them owning the full lifecycle for one of Indonesia's largest multi-finance companies. The work spans product development, growth, and discovery across financial services, client engagements, and projects I built for myself. Each context is different but the approach is consistent. I start with how the business actually operates before touching the roadmap. That is where the real problem usually lives. I came into product from a content and marketing background, and that still shapes how I think about features: something users have to understand, choose, and come back to, not just something that gets shipped. Based in Jakarta, and open to product roles or consulting where the gap between how a business runs and how its digital product works is the actual problem to solve.

Hi I’m Eulis 👋🏻 a QA Manual Tester and Technical Writer with 3+ years of experience working on web and mobile applications (Android & iOS). In my QA role, I focus on understanding requirements, creating test cases, running manual tests, and reporting bugs clearly so developers can fix issues efficiently. I’ve worked with both new features and regression testing, making sure the product works as expected before release. As a Technical Writer, I create clear and practical documentation such as user guides, user manuals, release notes, and API documentation. I enjoy turning complex systems into documentation that’s easy to understand for both technical and non-technical users. I usually work with tools like Notion, Google Docs, Google Sheets, and common project tracking tools to keep everything organized and transparent. I’m detail-oriented, easy to work with, and communicate clearly throughout the project.
