About
I’m Attila Sikora — a senior software engineer. I’ve been building business systems for 13+ years, and today I build AI-powered solutions for Hungarian SMBs.
My career has revolved around enterprise systems: manufacturing (ERP–MES), warehouse automation, banking and telecom software — currently working as a senior software engineer at a global market-research technology company, on system integrations. Along the way I launched three products of my own on the Hungarian market, built from scratch and run in production by me.
I don’t know NAV integration from a textbook: I built an Online Számla integration microservice in an enterprise setting, and today I help businesses with the eNyugta switch and invoicing APIs (Billingo, Számlázz.hu). My focus is AI agents and business-process automation — where they bring measurable value, not just look good in a demo.
If there’s a recurring, time-draining task in your business, or an idea you’d like turned into software — let’s talk.
Where I come from
Industries where I’ve built production systems:
Market-research technology
Integrating internal and external systems, data-model mapping and traffic orchestration, on cloud infrastructure (AWS).
Warehouse automation
Central control of automated warehouses (MFS/WMS): stacker cranes, conveyors, self-driving forklifts.
Manufacturing (ERP–MES)
Nearly 9 years: order-to-invoice workflows, NAV Online Számla integration, message-queue-based systems.
Banking & telecom
Bank cashier application and network configuration-management systems.
Services
How I can help — from the first idea to a system running in production.
Custom software & MVP development
Fast, transparent development of web apps and MVPs — from a testable first version to a product that scales.
NAV integrations
Connecting eNyugta, e-cash-register and invoicing APIs (Billingo, Számlázz.hu) with reliable, regulation-aware solutions.
Process automation for SMBs
Replacing repetitive manual work: data sync, reports, notifications. Less spreadsheet juggling, fewer mistakes.
Consulting & technical audit
Stuck on a project or a decision? I review the system and give you a clear, actionable recommendation.
AI in practice
A few examples of what well-targeted AI automation can do in an SMB’s everyday work:
Document processing
Data from invoices, contracts and emails extracted and organized automatically — you review instead of retyping.
Customer communication
Incoming email triage, reply drafts and follow-ups in your own tone of voice.
Reports & summaries
A weekly business brief generated from your own company data, in plain language — the way Pénzlátó does it.
Internal copilot
A company-specific knowledge assistant for your team: price lists, processes, policies — with instant answers.
No AI team or big project needed: we start with a small, well-targeted automation, and measurable results decide what comes next.
My own products
Not case studies — these are live, working products that I built and operate.

Why work with me?
A developer who understands the Hungarian SMB reality — not just the code.
Direct communication
No account managers, no telephone game — you talk to the person who writes the code.
I ship fast
Three live products and 13+ years of enterprise engineering prove it: the path from idea to a working solution is short.
I know the local terrain
NAV regulation, invoicing APIs, SMB reality — no need to explain it from zero.
AI where it actually helps
No hype: I add AI only when it saves measurable time or money.
