I set up Odoo, configure it around how a business actually runs, build the custom modules standard Odoo doesn't cover, and stay on for support after go-live. Odoo 16 through 19, odoo.sh and self-hosted Most companies I work with are somewhere in the same place: they either just bought Odoo and don't know how to make it fit, or they've been running it for a year and half the processes still live in spreadsheets. That's the work I take What I do Implementation and deployment - odoo.sh, Docker, or your own server. Staging/production branches, backups, upgrades, CI. I don't hand over a system that only works on my machine. Configuration - Sales, CRM, Purchase, Inventory, Manufacturing, Accounting, Projects, Website/eCommerce. Multi-company and multi-currency setups, user roles and record rules, approval flows. Configure first, code only where configuration genuinely can't do it. Custom module development - Python, XML, QWeb, OWL. New models and business logic, automated workflows, custom PDF reports and print templates, portal pages for clients or suppliers, dashboards. Migrations and data โ€” moving from spreadsheets or another ERP into Odoo, version upgrades (16-17-18-19), data cleaning and import with real validation, not just a CSV dump. Integrations - payment and shipping providers, marketplaces, external APIs, Telegram bots for approvals and notifications, and any third-party system over REST or JSON-RPC. Support and maintenance - bug fixes, performance work on slow databases, small feature requests, ongoing retainer if that's what you need. How I work I own the technical side so you don't have to manage it. I'll tell you when a request is a bad idea and what to do instead, and I'll tell you when something is out of scope rather than quietly padding the invoice. Clear scope, direct communication, no hand-holding required. Recent work Multi-company Odoo 19 setup for a cosmetics manufacturer - separate legal entities, shared product catalogue, and a restricted client portal so partner brands see only their own orders and production status. Odoo 19 on odoo.sh for a private clinic - eight custom modules covering appointments, treatment records, staff scheduling and consent documents, plus full localisation into a second language. ERP migration for a German e-commerce company - product, stock and order history into Odoo without stopping the shop. Insurance broker module (Odoo 18) - policy and renewal tracking, custom QWeb print templates, Telegram bot for agent notifications. Also available for Full-stack and backend work outside Odoo: web apps and APIs, SaaS products, Claude/LLM integration, Telegram bot backends, AWS deployment. Recent example โ€” an AI CRM analytics platform: sales teams connect HubSpot, Salesforce or Pipedrive, data syncs every 15 minutes through a Redis job queue, and the team asks questions about their pipeline in plain English. Built on Node/TypeScript with a multi-tenant Postgres backend. Stack Odoo: Odoo 16โ€“19, odoo.sh, custom modules (Python/XML), QWeb, OWL, ORM, JSON-RPC/XML-RPC, Odoo Studio, OCA modules, data migration & version upgrades Backend: Python, Node.js, TypeScript, FastAPI, Django, Express/NestJS, Laravel (PHP), C#, Java, Celery, BullMQ, WebSockets, REST, GraphQL, gRPC Frontend: React, Next.js, TypeScript, Angular, Vue, Tailwind CSS, Vite, shadcn/ui, HTML/CSS Databases: PostgreSQL, MySQL, Supabase, Redis, MongoDB, Elasticsearch, query optimization & indexing Infrastructure / DevOps: Docker, Docker Compose, Nginx, Linux (Ubuntu/Debian), AWS (EC2, S3, RDS), Google Cloud, Railway, Kubernetes, Terraform, GitHub Actions, CI/CD, Cloudflare, Sentry, Prometheus/Grafana AI & automation: Claude API, Anthropic MCP, OpenAI API, LangChain, RAG & vector search (pgvector), n8n, Zapier, Claude Code, prompt engineering, ML model integration Integrations: Stripe, PayPal, HubSpot, Salesforce, Pipedrive, Shopify, WooCommerce, Telegram Bot API, Google OAuth / Calendar / Drive, Twilio, webhooks Tools: Git, GitHub, Jira, Postman, pytest, Playwright, Figma
