Engineering discipline.Enterprise scale.
We partner with CTOs and product teams building complex software — multi-tenant SaaS, system integrations, mobile platforms. Senior engineers, direct accountability, zero overhead.
What we've built
Projects that moved the needle.
.NET monolith → microservices
Migrated a 10-year enterprise system to event-driven microservices over 5 months — without interrupting live operations for a single day.
CRM + AI sales automation
Custom CRM with AI-driven WhatsApp outreach — automated lead qualification, follow-up sequences, and real-time performance dashboards.
Multi-market subscription platform
Per-region pricing engine, white-label tenant support, role-based access control, and full Stripe billing with webhook automation.
Technology stack
The right tools. For the right job.
We choose technology based on the problem — not trends. Every tool below is battle-tested across real production systems.

How we work together
Three ways to engage.
Staff Augmentation
Your team. Our engineers.
1–5 senior engineers embedded in your existing team. Your processes, your tools, your sprint cadence — we plug in and contribute from day one.
Ideal for: Already have a team, need senior capacity fast
Dedicated Squad
Your product. Our team.
A full self-managed squad — tech lead, developers, QA — assigned exclusively to your product for 3–12+ months. Full ownership, full velocity.
Ideal for: Building from 0 to 1, or scaling an existing product
Project Build
Your brief. Our delivery.
Fixed scope, fixed timeline, milestone-based payments. We define the architecture, deliver working software, and hand over full ownership.
Ideal for: Clear scope, defined outcome, budget certainty
Engineering standards
What you get. By default.
Every engagement. Every project.
Non-negotiable standards.
2-week sprints
Every sprint ends with a working demo. You get Jira board access and join sprint reviews — always knowing what ships next.
Mandatory code review
Every PR requires 2 senior approvals + all automated tests passing before merge. No shortcuts, no exceptions.
Staging environments
Every feature branch gets a live staging deployment. You test before it touches production. No surprises at launch.
≥ 80% test coverage
Unit, integration, and E2E tests enforced via CI pipeline. Coverage reports attached to every build, tracked over time.
Weekly sync
30-min video call every week. Daily async updates via Slack or Teams. You're never left guessing what's happening.
Security-first
OWASP checklist, dependency scanning, secrets via Azure Key Vault or HashiCorp Vault — enforced on every project, not as an afterthought.
Why LionCore
We work like an in-house team.
Senior-only engineering
Minimum 5 years per engineer. Team backgrounds include Cognizant, Pentalog, and international fintech — not junior developers learning on your budget.
Founders directly in the room
You always talk to decision-makers. No account managers, no communication layers — direct access, fast decisions, full accountability.
EU-grade, startup-agile
Romanian engineering talent with enterprise track records. Western European quality standards at Central European rates.
