I’m a senior developer (ex‑Baidu, 13+ years) focused on modern automation & AI — the kind that actually saves businesses time and money. What I do best: Take messy, manual processes (forms, spreadsheets, CRMs, Slack, APIs, AI) and turn them into reliable, low‑cost automated workflows — using n8n, make, Python, and Google Apps Script when you want to avoid paid subscriptions. Recent real‑world examples: · B2B lead automation (production mode): Tally → n8n → DeepSeek enrichment/scoring → Google Sheets → Slack Assign/Junk/Nurture → HubSpot Contact + human‑approved email DRAFT → Calendly sync → daily/weekly digests. Full observability with OpenTelemetry, Jaeger, and Langfuse (correlation_id end‑to‑end). Not a mock demo — gated test→production rollout. · Typeform → Airtable → Google Sheets (branch mapping, deduplication, error logging). Moved logic to Google Apps Script so the client avoided an Airtable upgrade. Late changes free → 5‑star feedback & a return project. · Discord e‑commerce bot (Stripe sandbox, webhooks, automatic card delivery, CSV exports). Full buy‑to‑delivery loop. · Custom RSS scraper + AI analysis + Telegram/Discord alerts (n8n, Python, local LLM, RAG). Scores and filters opportunities against resume criteria. Tech I use daily: n8n, make, Python (FastAPI, pandas, openpyxl), Google Apps Script, Docker, CI/CD, REST APIs, webhooks, HubSpot, Slack, AI (DeepSeek, OpenAI, Ollama), and monitoring (OpenTelemetry + Jaeger + Langfuse). Why me? · I don’t just “connect APIs” — I design for error handling, retries, logging, and what happens if something breaks at 2am. · I respect your budget: free/low‑cost first, scale only when needed. · 13 years of corporate engineering (Baidu) means clean delivery, documentation, and systems you can hand off. Let’s talk about your repetitive task — I’ll show you a faster, cheaper way to automate it.
