I am a tech-agnostic data engineer who enjoys solving complex data problems, finding patterns in messy datasets, and making sure the work actually supports the business. My focus is always on clean architecture, performance, and making data useful - not just moving it around.Here is what I have worked with: - Programming & Scripting: Python (Flask, FastAPI, Django, Selenium, PySpark), SQL - Data Engineering & Integration: Talend, Mage.ai, Apache Airflow, Airbyte, Databricks, Kafka, Debezium - Databases & Data Warehousing: Data Modeling, PostgreSQL, MySQL, Snowflake, Greenplum, MongoDB, Firebase, ClickHouse - Cloud & DevOps: AWS (Lambda, API Gateway, S3, RDS, SQS and more), Docker, Kubernetes, Azure DevOps, Terraform, CloudFormation - Security & Compliance: Secure and compliant pipeline design (HIPAA, GDPR, SOC 2), data governance, privacy-first architectures - Testing & Automation: Postman, Cypress.io, Swagger, Automated Data Workflows - Data Visualization: Power BI, Metabase, Google Data Studio, Grafana - Collaboration & Leadership: Cross-functional team mentoring, process optimization, data-driven decision-making

I automate finance and operations workflows that are still being handled through spreadsheets, inboxes, and manual CRM updates. Using n8n, OpenAI, APIs, and webhooks, I build observable workflows for reconciliation, document intake, invoicing, lead routing, approvals, retries, and alerts. The difficult part of automation is rarely connecting two applications. It is preventing duplicate records, handling missing data, controlling retries, maintaining an audit trail, and ensuring the right person is notified when a workflow cannot complete safely. Selected automation work: • Built a LangChain financial reconciliation workflow connecting data across more than 10 enterprise systems • Developed a GPT-4 scoring pipeline that processed more than 52,000 users without manual review • Built a real-time OpenAI API pipeline using Node.js and AWS Lambda to transform streamed XML chunks into structured JSON • Delivered a secure searchable database and controlled-access interface for operational spreadsheet data • Built an AI-powered document workflow that converts uploaded study materials into structured notes, summaries, quizzes, flashcards, and PDFs I can help with: • n8n workflow design, implementation, and troubleshooting • CRM lead intake, enrichment, scoring, routing, and follow-up • Finance reconciliation, invoice processing, and approval workflows • OpenAI-powered document classification and structured extraction • API, webhook, email, database, and spreadsheet integrations • Make and Zapier automation • Duplicate prevention, idempotency, retries, and stopping conditions • Human-review and approval checkpoints • Workflow logging, alerts, and audit trails • Python, Node.js, and AWS Lambda integration services • Technical documentation and team handover I use AI only where interpretation or generation is genuinely required. Deterministic tasks such as validation, calculations, routing rules, record matching, and status updates remain rule-based whenever that produces a more reliable and cost-efficient system. With 10+ years of software engineering experience, I can build both the workflow and the custom infrastructure required around it, including APIs, databases, authentication, background processing, monitoring, and deployment. Send me the process you currently perform manually, the systems involved, and the exceptions your team encounters. I will identify what should be automated, where human approval should remain, and the most dependable implementation approach.
