System Integration for Small, Medium, and Enterprise Environments


Professional experience includes connecting systems for small and medium-sized companies as well as enterprise organizations, with a focus on simplicity, reliability, and transparency.

For scenarios involving one or a few integration points — CRM, ERP, eShop, Billing, Accounting, partner APIs, cloud services, or internal tools — integrations are designed and implemented to be:

  • easy to understand,
  • easy to maintain,
  • and fully owned by the company

In addition, experience includes work on larger integration landscapes involving multiple domains, teams, and systems typical of enterprise environments.

No vendor lock-in. No black boxes. No unnecessary platforms.

Enterprise integration experience includes work on large-scale, multi-domain system landscapes typical of telecom and regulated enterprise environments. This covers the design and governance of integration architectures across CRM, billing, order management, mediation, and identity systems, as well as API and event-driven integration patterns applied across multiple teams and operating companies. Experience spans architecture definition, integration standards, data models, and controlled system evolution in complex, long-running enterprise platforms.

Typical use cases

  • Connect eShop with CRM / ERP
  • Synchronize customers, products, orders, invoices
  • Integrate billing, payments, accounting
  • Connect partners or third-party APIs
  • Integrate cloud services (storage, messaging, analytics, authentication)
  • Replace manual exports/imports with automated flows
  • Simplify or stabilize existing fragile integrations

If systems can exchange data via APIs — they can be integrated.

How I work

  1. Short assessment. A typical engagement includes:
    • review of existing systems, requirements, and constraints;
    • definition of a clear and realistic integration approach.
  2. Fixed-scope delivery model. Especially for small scopes (1–3 integration points). Defined scope, timeline, and effort parameters — reducing uncertainty in similar engagements.
  3. Implementation with open code
    • Clean, well-structured integration logic
    • Source code is fully transferred to you
    • No proprietary frameworks or hidden dependencies. You are not locked into a vendor or long-term contract.
  4. Optional post-delivery activities. Professional experience also includes the organization of monitoring and support setups for integrated systems. This typically involves:
    • defining monitoring and alerting requirements;
    • designing operational handover processes;
    • preparing documentation for operations, support, and troubleshooting;
    • supporting the transition of integrations into production environments.

Ongoing operation and support are typically handled by the client’s internal teams or designated experts, based on the provided documentation and handover materials.

Integration approach

Depending on the business context and organizational scale, the most appropriate integration approach is applied:

  • Tailor-made APIs. APIs designed around your real business processes, not abstract models.
  • Industry standards where they add value, particularly in enterprise and multi-vendor environments. For example, TM Forum Open APIs when working with telecom or telecom-related systems, where standardization improves interoperability.
  • Pragmatic integration patterns. When full standard compliance would add unnecessary complexity or overhead, lean and practical integration designs are applied that still ensure reliability, scalability, and clarity.
  • Cloud platform APIs. Direct integrations with services from Google, Amazon, and Microsoft Azure — such as storage, messaging, identity, monitoring, and automation services.

The underlying objective in such integrations is to achieve stable solutions that address current needs without limiting future changes.

Why this approach works across different organizational sizes

  • Fixed-scope delivery for clearly defined integration efforts
  • Fast delivery for small integration needs
  • Open-source delivery — you own the integration
  • No vendor lock-in or proprietary platforms
  • Enterprise-level experience, applied pragmatically


Typical fit in scenarios where organizations, ranging from small teams to enterprise departments:

  • Need one or a few integrations, not a multi-year program
  • Prefer predictable scope and effort over open-ended consulting
  • Care about owning the code and architecture
  • Prefer simple, robust solutions over heavy integration platforms
  • Want the freedom to continue with your own team or another vendor later
