Clearer operating decisions
Turn scattered requirements and information into a shared view of priorities, responsibilities and the next useful release.
Greenwall services
Custom software, integrations and automation for business.
Greenwall helps owners and operations teams build business applications, connect systems and automate repeated work. We work remotely across Bulgaria and Europe, with client-site work in Sofia by arrangement.
The context
A focused partner for business systems that need clarity and continuity.
The work can begin with a process, fragmented data, an integration problem or a product idea. We connect business discovery with software design, implementation, testing, deployment and production visibility, so decisions are not separated from delivery.
Greenwall is founder-led today. Engagements are led directly by Nik Nenkov, with additional specialists assembled to an agreed scope when the work calls for them. Building stable whole-team delivery capacity is a deliberate direction for the company, not a claim of a permanent bench today.
Greenwall is registered in Sevlievo and has no public office. Work is available at client sites in Sofia, through hybrid collaboration in Bulgaria and remotely across Europe when the context and working model fit.

Relevant experience
Experience behind the offer
The services draw on founder Nik Nenkov’s more than eight years of software experience, including employment and independent projects. Greenwall was incorporated in 2024; earlier work is founder experience, not company history or a list of Greenwall clients.
Operational and back-office systems
A staged cross-border operations platform connects ERP records, warehouse views and role-based administration. The case study separates its working foundation, pilot capabilities and planned modules.

Delivery partners
You need senior hands-on capacity or a carefully assembled group for a defined scope.
Questions
Questions before a first conversation
Does Greenwall work only on new software?
No. An engagement can improve an existing product, untangle an integration, automate a process, consolidate data or define a responsible modernisation path.
Can Greenwall provide a complete software team?
Greenwall is founder-led today. For an agreed scope, Nik can lead the work and assemble appropriate specialists. A permanent multi-person delivery bench is a future company direction and is not presented as current capacity.
How does remote collaboration work?
The work is organised around clear decisions, written context, visible increments and regular conversations with the people who own the business outcome.
