Productized consulting · Platform decisions

De-risk the next platform decision.

Time-bounded packages for the moments when architecture, security, delivery, observability, or applied AI need an independent senior perspective and a practical route forward.

  • Senior architecture leadership
  • Evidence-aware, outcome-led work
  • Cloud-native, vendor-neutral approach
  • Europe-based, working internationally
Ways to start

A useful boundary for the uncertainty in front of you.

Choose a package when a clear first result matters more than a large programme plan. Each one can stand alone or become the first phase of deeper architecture and engineering support.

Package 013–4 weeks

Cloud-Native Platform Security Assessment

Security risk in a shared platform rarely comes from one missing product. It appears in the gaps between architecture, delivery, identity, tenancy, detection, evidence, and accountable operation. This assessment turns those gaps into a decision-ready view of risk and the next practical moves.

  • Executive security posture brief and platform boundary map
  • Platform threat model covering supply chain, authority, tenancy, detection, and dependencies
  • Control and maturity view informed by Kubernetes, cloud-native, NIST, CIS, and relevant organizational criteria

Package 022–3 weeks

Architecture Decision & Target-State Sprint

Important architecture decisions become expensive when the real constraints stay implicit. This sprint creates a shared decision context, compares viable options, makes trade-offs visible, and leaves delivery teams with a target state they can use.

  • Decision brief with goals, constraints, stakeholders, and evaluation criteria
  • Option analysis with explicit trade-offs and quality-attribute assessment
  • Target-state and transition architecture views

Platform Product & Delivery Blueprint

Internal platforms create leverage when they make the safe path the understandable path. This blueprint connects developer journeys, platform capabilities, delivery workflows, policy, reliability, and ownership into an incremental product direction.

  • Platform consumer and user-journey map
  • Capability model, product boundaries, and reference architecture
  • Paved-road and self-service workflow design

Package 042–3 weeks

Observability & OpenTelemetry Blueprint

Observability becomes expensive and noisy when instrumentation, collection, storage, alerting, and ownership evolve separately. This blueprint connects the signals to the operational questions they should answer and the teams responsible for acting on them.

  • Observability maturity and telemetry-flow assessment
  • OpenTelemetry collection, routing, and backend architecture
  • Signal quality, metadata, sampling, and retention standards

Applied AI Opportunity & Architecture Sprint

AI initiatives create durable value when the task, context, tools, permissions, evaluation, and human ownership are designed together. This sprint helps engineering leaders choose a practical workflow and leave with an architecture that can be tested and responsibly adopted.

  • Use-case and workflow assessment with a measurable success baseline
  • Agent, context, retrieval, and tool architecture
  • Permission, data-boundary, security, and human-approval model

Consulting covers discovery, target architecture, technical design, delivery guardrails, and implementation support—keeping strategic intent connected to what runs in production.

Mihály Petrényi, Enterprise Solution Architect and Technology Consultant
Independent senior counsel

One accountable partner from direction to delivery.

I’m Mihály Petrényi. I work directly with technology leaders and engineering teams, bringing architecture-level perspective close enough to implementation to remain useful.

About my approach
When the work grows

Let the first package earn the next phase.

A focused assessment or sprint can lead into target-state design, delivery guardrails, implementation guidance, or ongoing architecture support when the context calls for it.

Explore capabilities
Operating approach

A practical route from ambiguity to action.

01

Understand

Establish context, constraints, risks, and the decisions that matter.

02

Design

Create a coherent target architecture with explicit trade-offs.

03

Validate

Test assumptions through review, prototypes, and operational scenarios.

04

Enable delivery

Translate decisions into guardrails and support teams through execution.

Active engineering project

FleetPilot

FleetPilot is a self-hosted, Kubernetes-native control plane that turns enterprise inventory into OpenTelemetry Collector configuration through the Open Agent Management Protocol.

The project explores how collector registration, configuration, secret boundaries, and telemetry fleet operations can become safer and easier to operate at scale.
