Services / SaaS, ERP & Fintech
SaaS, ERP & Fintech
Multi-tenant business software with secure, scalable foundations — from ERP/POS systems to real-time trading platforms.
What’s included
- Multi-tenant architecture design — data isolation, tenant provisioning, per-tenant customization
- Real-time data sync (WebSockets, queues, background jobs)
- Payment gateway integrations and subscription billing logic
- ERP/POS modules: inventory, orders, reporting, multi-location support
- Security-first architecture: auth, role-based access, audit trails
- DevOps: Docker-based deployments, CI basics, staging environments
Relevant work
ERP OrbitSync (multi-tenant ERP/POS, 10+ live deployments), VelocePlus (UK–Moldova parcel delivery with real-time tracking), and a MetaTrader-style Trading Terminal with live market data. See more on the Portfolio page.

SaaS, ERP and fintech development for operational software
These products share the same underlying challenge: business rules have to remain reliable as users, transactions, tenants, integrations, and data volume grow. I focus on the architecture that keeps those systems maintainable—clear tenancy boundaries, role-based permissions, predictable background jobs, auditability, API integrations, and deployment practices that support ongoing development.
Choose the product path that matches the requirement
- SaaS product development — subscription products, multi-tenant foundations, dashboards, onboarding, billing, and product APIs.
- Custom ERP and POS development — inventory, orders, reporting, multi-location operations, permissions, and business-specific workflows.
- Trading platform development — real-time market data, WebSockets, broker/exchange integrations, alerts, and trading workflows.
- Fintech and payment integrations — gateways, subscriptions, webhooks, transaction workflows, and external financial services.
Start with the smallest architecture that can support the product
Not every SaaS product needs complex microservices, and not every ERP needs every module on day one. The better approach is to identify the first useful workflow, define the data and tenancy model correctly, and build a foundation that can accept additional modules without forcing a rewrite. The same principle applies to fintech: simplify product scope where possible, but do not cut corners around transaction state, audit logs, permissions, or reconciliation.
The ERP OrbitSync case study provides production context for multi-tenant ERP/POS work. For planning, read SaaS vs. custom ERP if you are deciding whether to build at all, or the fintech trading platform cost guide if the product includes real-time market or financial workflows.
What to prepare before development
Document the primary user roles, organizations or tenants, core transactions, reporting needs, required integrations, and what must be available in the first release. For an existing product, include the current architecture, framework versions, production constraints, and the specific operational problems you want to fix. That information is enough to begin an architecture and scope discussion.
