Common Challenges
Problems We Help Buyers Solve
Teams evaluating e-commerce development typically hit these blockers before finding a reliable partner.
Generic agencies miss vertical nuance
Healthcare, fintech, and edtech need domain-aware architecture — not template CRUD apps.
Compliance bolted on late
Retrofitting HIPAA, PCI, or FERPA after build is expensive and risky.
Integration sprawl
Industry tools (EHR, LMS, payment gateways) need careful API orchestration.
Release fear in regulated markets
One bad deploy can mean audit findings or customer trust loss.

“What a 70-engineer team could not deliver, a small senior team at GreeLogix shipped. The app went from stuck to live across mobile, web, and backend.”
