Nik Nenkov
Business Technology Consultant | Full-Stack Developer
I’m Nikolay Nenkov, also known professionally as Nik Nenkov (Николай Ненков). Through Greenwall Business Systems, I build and improve business software, API integrations and Java/Spring applications. Based in Sevlievo, Bulgaria; available for client-site work in Sofia, hybrid collaboration in Bulgaria and remote work across Europe.
Perspective
The useful work happens between the business question and the technical answer.
I work at the intersection of business management, software development and practical technology. My experience includes Java/Spring services, React and TypeScript interfaces, SCSS, integrations, delivery leadership and turning operational needs into usable solutions.
I bring hands-on software delivery, former student-tutor experience and practical business technology judgement to work with owners, managers, operations, product, marketing, sales and engineering teams.
I am most useful where the situation is not yet perfectly defined — where business context, technical judgement and a clear path forward need to come together.
Understand the system. Clarify the decision. Build what helps.
Selected practice
A portfolio of capabilities, not a list of job titles.
My work connects design‑level thinking with hands‑on delivery across business software and operational digitalisation.
Software delivery
Designing and improving maintainable applications, distributed services and observable delivery flows.
- Distributed systems
- Test automation
- Cloud delivery
Technical partnership
Helping owners and teams diagnose existing solutions, coordinate work and choose the next responsible step.
- Stakeholder alignment
- Roadmaps
- Team mentoring
Ways to work together
Three clear ways to move a difficult system forward.
Choose the smallest engagement that can produce a useful decision and a credible delivery path.
- 01
Operational Systems Assessment
A paid, time-boxed discovery producing a process and data map, visible risks and priorities, an architecture and delivery roadmap, and pragmatic next steps.
- 02
Build & Delivery Leadership
Senior technical direction with hands-on implementation of critical paths, aligning owners, operations, product, suppliers and engineering from decision to release.
- 03
Fractional Technical Partner
Ongoing technical leadership for roadmap, supplier and team coordination, architecture choices and continuous delivery improvement.
Working principles
A grounded way to approach complex work.
- 01
Context before tooling
The right technical choice starts with how the business works and what must improve.
- 02
Clarity before scale
A system becomes easier to grow when its purpose, ownership and boundaries are understandable.
- 03
Delivery with continuity
Useful software should remain maintainable after the first release and the first team change.
