What I do

Consulting services

Senior technical consulting, boutique model: few clients, full ownership, and engagements you can scale from a one-off project to an ongoing retainer.

Solutions architecture

Systems that scale without a rewrite every six months.

Architecture design and modernization: monoliths to microservices, well-designed APIs and Docker containers for reproducible, no-surprises deploys.

Deliverables

  • Current architecture diagnosis
  • Target architecture design
  • Phased migration plan
  • Containerization and deploy
Ideal for: Teams whose systems outgrew their architecture.

Real AI automation

Agents that execute, not just reply.

Agent orchestration (CrewAI), local LLMs (Ollama), RAG and MCP to automate business flows 24/7 with guaranteed data privacy.

Deliverables

  • Agent ecosystem design
  • Local private inference
  • RAG + MCP integration
  • Docker deploy with observability
Ideal for: Companies that want to automate real operations—not install a chatbot.

High availability & performance

It must not fall when it matters most.

Backend optimization, redundancy, balancing and observability to sustain high volume under rigorous corporate standards.

Deliverables

  • Performance audit
  • Redundancy and scaling strategy
  • Observability and alerts
  • Ops runbook
Ideal for: Critical systems where downtime has real business cost.

End-to-end full-stack development

From backend to pixel.

Complete platforms (Python/Node + React/Django/Flask), commerce, payments and funnels, with end-to-end product ownership.

Deliverables

  • End-to-end product
  • Backend and APIs
  • Frontend and UX
  • Business automations
Ideal for: Founders and companies that need senior product building, without relying on half a junior agency.
How I work with companies
01

Diagnosis

I understand the technical and business challenge, review the current architecture and define a measurable goal on the very first call. Deliverable: risk/opportunity map.

02

Design

Target architecture with explicit trade-offs (cost, privacy, time-to-market, ops). Deliverable: diagram + phased plan.

03

Implementation

I build with end-to-end ownership, evidence and observability, without taking down your ops. Deliverable: deployable system.

04

24/7 operation

I leave the system measurable and operable — runbooks, health checks, traces — and, if your team prefers, I stay on as an ongoing retainer for continuous evolution. Deliverable: autonomous ops with clear signals.
