What I can help you with

Senior technical work across backend development, Odoo, eCommerce systems, automation and applied AI. Each service reflects years of hands-on work in real business environments.

Backend Development & Architecture

Design and development of maintainable backend systems, APIs, business logic, integrations and data flows.

Well-designed backend systems are the foundation of reliable business software. The focus is not only on making things work, but on making them maintainable, testable and adaptable as the business grows.

What this covers

  • REST APIs
  • Node.js
  • Java / Spring Boot
  • PostgreSQL
  • Elasticsearch
  • Clean Architecture
  • Domain-Driven Design
  • Performance Optimization
  • Batch Processing

Odoo Implementation, Customization & Integration

I help companies implement, adapt and integrate Odoo with their real business processes.

Odoo works well as a base, but many companies need it adapted to the way they actually operate. Standard workflows rarely fit perfectly — and forcing your business to match the software is rarely the right approach.

What this covers

  • Odoo Setup & Configuration
  • Custom Modules
  • Workflow Customization
  • Sales, Purchasing & Inventory
  • Invoicing Flows
  • eCommerce Integration
  • ERP & Marketplace Connections
  • External API Integrations
  • Administrative Automation
  • Implementation Review

eCommerce Systems & Integrations

Product catalog automation, ERP and marketplace integrations, search optimization and data synchronization for commerce at scale.

eCommerce operations involve a complex web of systems — ERPs, warehouses, marketplaces, search engines and front-end platforms. Making these work together reliably is a core technical challenge that directly impacts revenue.

What this covers

  • Product Catalog Automation
  • ERP & Marketplace Integrations
  • Search Optimization
  • Elasticsearch
  • Product Data Enrichment
  • Import / Export Processes
  • Pricing & Stock Synchronization

Business Process Automation & Applied AI

Applied AI should solve real operational problems, not exist as a buzzword.

The most valuable automations eliminate manual, error-prone tasks that drain team time and create operational risk. AI adds a new layer — enabling tasks that were previously impractical to automate, such as extracting meaning from documents, enriching data at scale or routing information intelligently.

What this covers

  • AI-Assisted Product Descriptions
  • Product Categorization & Attribute Extraction
  • PDF, Invoice & Document Data Extraction
  • Internal Assistants on Business Data
  • RAG over Company Documentation
  • Email Classification & Response Drafting
  • Odoo + AI Workflows
  • AI Integrations into Existing Applications

Technical Consulting & Refactoring

Architecture reviews, refactoring plans, legacy system modernization and technical decision support.

Growing systems accumulate technical debt. At some point, the cost of that debt — in slower delivery, higher risk and harder maintenance — becomes higher than the cost of addressing it. Refactoring and architecture improvements pay off when done with a clear plan and business priorities in mind.

What this covers

  • Architecture Review
  • Refactoring Plans
  • Legacy System Modernization
  • Performance Bottleneck Analysis
  • Technical Decision Support
  • MVP Technical Planning

Blockchain & Web3 Development

Building reliable blockchain integrations and Web3 systems with a focus on real business utility.

  • Smart contract development (EVM / Solidity)
  • Web3 backend APIs and indexers
  • On-chain / off-chain data synchronization
  • Wallet and token integrations
  • DeFi protocol integrations
  • NFT systems and metadata pipelines
  • Blockchain data indexing (The Graph, custom)
  • Legacy system blockchain integration

How we can work together

Pricing reflects senior-level work and is structured to fit different kinds of engagements. Most projects work better as a fixed quote or a monthly retainer than as raw hourly billing — but every engagement starts with a free call to understand the real scope.

Hourly

From €75/h

For short tasks, support, consulting calls or ad-hoc technical work. Billed by tracked time, invoiced monthly.

Fixed project

Quoted per scope

Closed-scope work with a clear deliverable — an integration, an Odoo module, a refactor plan, an MVP. Quoted after a discovery call so both sides know what is being built.

Monthly retainer

From €2,000/month

30 hours reserved per month as your part-time technical partner. Best for companies with continuous evolution needs that do not justify a full-time hire. ~11% discount vs hourly.

Discovery call

Free · 30 min

Initial call to understand your context, scope and constraints. No commitment — at the end of the call we both know if there is a good fit.

Rates above are starting points for engagements based in the EU. Complex, time-critical or specialized work (blockchain, performance audits) may be quoted higher. VAT not included.
