Secure Systems. CI/CD by Design. Architecture that Endures.
Software engineering at Zero One Logic means more than delivery—it means discipline. We don’t just build applications. We design systems with longevity, security, and operational fit from day one. Whether in finance, telecom, or the public sector, we bring engineering rigor to every layer—from interface to orchestration.
What We Engineer
We focus on software systems that must remain robust under pressure and compliant by default:
- Regulated and Audit-Ready Applications
Designed with built-in logging, traceability, and security controls. - CI/CD-native Architectures
Engineered for automated pipelines and continuous validation from test to production. - Highly Available Microservices
Architected for graceful failover, redundancy, and scalable performance. - Multi-tenant Systems with Fine-Grained Access
Supporting internal segmentation, RBAC, and integration with external IAMs. - Cloud-agnostic Software
Kubernetes-native but cloud-neutral—flexible to your runtime, portable across providers.
Our Engineering Principles
Software is engineered to serve—safely, efficiently, and reliably. Across domains, we bring the same architectural mindset:
- Reproducibility
Every environment, from dev to prod, built and validated through code (IaC/GitOps). - Testability
Unit, integration, and regression testing embedded early and throughout the lifecycle. - Observability
Structured logs, health checks, metrics and tracing—not bolted on, but foundational. - Security-First Thinking
CI/CD pipelines with inline scanning, least-privilege execution, and shift-left enforcement. - Documentation as a Deliverable
From interfaces to build pipelines—every engineered artifact is discoverable and reproducible.
Engineering in Practice: Tools That Deliver
Our engineering principles come to life through a carefully chosen, production-proven technology stack. Everything we build is designed to operate in modern, automated, and security-aware environments—from the first commit to production deployment. This isn’t a list of tools—it’s a blueprint for scalable, resilient software in complex industries.
Languages & Frameworks
Python, Go, C/C++, Node.js, Bash, TypeScript, Vue.js, React, Angular
Interfaces & Protocols
REST, gRPC, OpenAPI-first schemas, OAuth2/OIDC-secured endpoints
Architecture & Automation
CI/CD-native by design, GitOps-ready with ArgoCD and Tekton

Infrastructure & Cloud-Native Delivery
Kubernetes, OpenShift, Docker, Podman, Helm, Operators
Infrastructure as Code with Terraform, Ansible, Puppet
Security & Compliance
FIPS, PCI DSS, HIPAA, SELinux, rootless containers, signed pipelines
Security and auditability built into every stage of the lifecycle
Observability
Prometheus, Grafana, ELK stack, Jaeger, Loki—embedded for insight and incident response
Big Data & ML Integration
Kafka, Spark, Hadoop
Advanced frameworks like TensorFlow and Hugging Face applied selectively in analytics-heavy environments
Testing & Validation
Automated testing pipelines with Playwright, Cypress, Jest, pytest
How We Work
Our software engineers integrate tightly with platform, infrastructure, and security teams. Whether embedded within your org or operating from our side, we work with:
- Architecture-First Approach
We engage early to shape application boundaries, state models, and deployment topology. - Secure-by-Design Development
All engineering is aligned to regulatory frameworks—PCI DSS, ISO 27001, FIPS, GDPR, HIPAA. - Lifecycle-Aware Delivery
Code and infrastructure evolve together—versioned, automated, and continuously validated. - Collaborative Execution
We act as partners, not vendors. Architecture reviews, threat modeling, and post-mortems are part of the process.

Where This Expertise Applies
Our engineering work supports clients where correctness and reliability are not optional:
- Financial Infrastructure
Trading, reconciliation, and compliance platforms with strict audit trails and resilience. - Telecom Control Systems
Multi-site orchestration, configuration validation, and regulatory isolation. - Energy & Utilities
Safety-critical workflows and time-series data pipelines for operational integrity. - Public Sector & Defense
Secure systems for classified environments, internal services, and multi-tenant management.
Example: We led the engineering transformation of a Swiss bank’s Linux estate into a fully automated, secure-by-design platform.
