Custom web systems
Admin panels, customer portals and internal tools that replace spreadsheets and manual processes.
Custom software
Every solution starts as a rough stone
Zextify designs, builds and maintains custom software. Web systems, APIs, integrations and automations — cut to fit your actual business problem, not a generic template.
- Continuous delivery
- You own the code
- Talk straight to the developers
Services
What Zextify builds
Fixed scope or an embedded squad. Either way, you talk directly to the people writing the code.
APIs and integrations
Documented REST APIs and integrations across the systems you already run — ERP, CRM, payment gateways, marketplaces.
WhatsApp automation
Support, notifications and automated flows on top of the Official WhatsApp Business API (Meta Cloud API).
Cloud and DevOps
Cloud infrastructure, deployment pipelines, observability and lower running costs.
Legacy modernization
Old systems nobody wants to touch: we map them, cover them with tests and migrate piece by piece, without stopping operations.
Discovery and architecture
Before any code: understanding the problem, sizing the effort and designing an architecture that survives growth.
How we work
From conversation to running software
A short process with clear decision points. No thirty-page proposals.
- 01
Understand
One conversation to map the problem, the constraints and what already exists. Free, no strings attached.
- 02
Size it
Scope, timeline and investment in writing, broken into deliverables — you approve before a single line of code.
- 03
Build
Short cycles with working deliverables. You follow progress in a real environment, not in a slide deck.
- 04
Sustain
After go-live: monitoring, fixes and continuous evolution as the business changes.
Technologies
The stack behind the deliveries
Mature tools, chosen for durability rather than hype. The final call always accounts for the team that will maintain the system afterwards.
