01
Marketplace backends
Inventory lifecycle, pricing tiers, order management, availability logic, and vendor feeds for high-volume platforms.
Backend engineering studio
We build backend systems for B2B SaaS and marketplaces.
Inventory, pricing logic, APIs, internal tools, and real-time features. Modular Laravel architecture built for maintainability, scale, and clear business rules.
Remote studio based in Ukraine · Serving US and international businesses
What we build
Backend-first. From domain modeling to production.
We design and build the systems behind your product — business logic, APIs, infrastructure. Not boilerplate. Not templates. Real architecture that handles real complexity.
02
B2B SaaS platforms
Multi-tenant architecture, role-based access, subscription billing, audit logs, and complex workflow automation.
03
Internal tools
Operations dashboards, admin panels, CRM integrations, reporting systems, and internal workflow platforms.
04
API & integrations
REST APIs, webhook systems, third-party integrations, background job pipelines, and real-time WebSocket features.
Secondary service line
For non-technical businesses: websites with inquiry systems.
Some companies do not need a SaaS backend yet. They need one professional place where customers can understand the business, request information, and send structured inquiries.
This service line is kept separate from the core backend studio positioning, but follows the same system-first approach: website → form → email delivery → optional dashboard.
Official websites for local, service, supplier, and small B2B companies.
Quote and inquiry forms with structured fields, spam protection, and email delivery.
Lead dashboards can be added later when email-only handling is no longer enough.
Simple first step for businesses that are not ready for custom backend development yet.
System experience
Backend patterns for products with real business logic.
Naelium focuses on the backend areas that usually become expensive to fix later: inventory state, pricing rules, permissions, integrations, background jobs, and operational dashboards.
Marketplace systems
Inventory & availability logic
Architecture for products where listings, stock, availability, suppliers, and fulfillment state must stay consistent across multiple workflows.
Inventory lifecycle — statuses, reservations, expiration, supplier feeds, and reconciliation
Pricing rules — markup logic, fee calculation, tiered pricing, and overrides
Order flow — availability check, checkout preparation, fulfillment, and delivery state
Stack focus: Laravel · PostgreSQL/MySQL · Redis · Queues · Docker
B2B SaaS
Multi-role operational platforms
Backend foundations for SaaS products where teams need permissions, workflows, audit history, data exports, and reliable internal tools.
Access control — roles, permissions, scopes, ownership rules, and audit trails
Workflow logic — state machines, approval flows, notes, assignments, and notifications
Operations UI — admin panels, dashboards, exports, filters, and reporting views
Stack focus: Laravel · Livewire/Vue · Redis · Horizon · REST APIs
Real-time & integrations
APIs, queues, and live updates
Systems where external services, background jobs, and real-time interfaces need to work without turning the backend into a fragile script pile.
API design — clean REST endpoints, validation, resources, versioning, and error contracts
Async processing — queues, retries, failed-job handling, imports, exports, and scheduled sync
Real-time features — WebSocket updates, live dashboards, notifications, and event streams
Stack focus: Redis · Horizon · Reverb/WebSockets · Docker · Linux
How we work
Architecture first. No surprises in scope.
Every project starts with a discovery phase. We understand the domain before writing a single line of code.
01 / Discovery
Understand
We review your product, domain logic, technical context, and goals. 30-minute call or written brief.
02 / Scope
Define
Clear Statement of Work: what's included, what's excluded, timeline, price, and payment terms. No ambiguity.
03 / Architecture
Design
Domain modeling and system design before development starts. You review and approve the approach.
04 / Build
Develop
Modular development with progress updates. Staging environment available throughout the project.
05 / Review
Verify
You test on staging before anything goes to production. Agreed revisions are included in scope.
06 / Handover
Launch
Full code, documentation, deployment support, and a 2-week post-launch window for critical fixes.
Tech stack
Senior-level expertise. Production-grade defaults.
We work within a focused, battle-tested stack. No framework chasing — deep expertise in the tools that handle real production loads.

FAQ
Answers before we talk.
What timezone do you work in?
We're based in Ukraine (UTC+3). We're available for morning US calls between 9am–12pm ET. Async communication works well for most of the project cycle.
Do you work with US companies?
Yes. Naelium works remotely with US and international companies. Payments can be handled via Wise Business in USD, with invoices issued before each project phase.
Do you sign NDAs?
Yes. We sign a standard NDA before any project details are shared. Confidentiality is the default — not the exception.
How do you handle scope changes?
Changes outside the agreed Statement of Work are documented as Change Requests with separate pricing and timeline adjustments. No surprise invoices.
What's your typical project size?
Scoped backend projects usually start from $5,000. Larger systems are estimated after discovery. Naelium works fixed-price for well-defined scope and time & material for ongoing development. 30–50% deposit before work begins.
How do discovery calls work?
Discovery can start with a written brief or a 30-minute Google Meet. Naelium asks about the product, technical context, domain logic, and goals. No pitch deck — just direct technical conversation.
Start a project
Send the technical context first.
Naelium works best when there is real backend complexity: domain logic, data workflows, pricing rules, inventory, APIs, integrations, or real-time behavior.
