core / frame build
Robust technical development for ambitious digital projects. We specialize in secure architectures, high-speed performance, and clean, maintainable code structures.
Who We Are
core / frame / build — Bilbao, Spain
Philosophy
We believe in engineering systems that endure. Every architecture decision is made with longevity, security, and performance as non-negotiable pillars. Our code is not just functional — it is maintainable, testable, and built to scale.
Approach
From secure backend architectures to pixel-perfect frontends, we deliver end-to-end digital systems. Our workflow is transparent, iterative, and rooted in measurable outcomes. No shortcuts, no technical debt accumulation.

Our Expertise
Enterprise-grade solutions engineered for performance, security, and scale.
Phase 1: Threat Modeling & Analysis
We conduct a comprehensive security audit of your existing infrastructure, mapping attack surfaces, identifying privilege escalation vectors, and cataloging third-party dependency vulnerabilities. Deliverables include a threat matrix, risk heat-map, and prioritized remediation roadmap aligned with OWASP Top 10 and NIST frameworks.
Phase 2: Architecture Implementation
Engineered zero-trust network topologies with role-based access control, encrypted communication channels (mTLS), and automated secret rotation via Vault integrations. Infrastructure-as-code templates provision hardened environments across AWS, GCP, or on-premise clusters with immutable build pipelines.
Phase 3: Validation & Hardening Delivery
Penetration testing across all entry points with documented CVE remediation. Final delivery includes security posture scorecards, incident response runbooks, automated compliance monitoring dashboards, and a 90-day continuous monitoring window with weekly vulnerability scan reports.
Phase 1: Performance Profiling & Baseline
Full-stack performance analysis using Lighthouse, WebPageTest, and custom profiling instrumentation. We measure Time-to-Interactive, First Contentful Paint, server response latency, database query execution plans, and edge cache hit ratios. Output: a detailed performance budget and bottleneck heat-map.
Phase 2: Optimization Execution
Implementation of server-side rendering pipelines, edge-cached static generation, code-splitting with dynamic imports, image optimization via WebP/AVIF pipelines, and database query restructuring with materialized views. Redis-backed session management and CDN configuration for global low-latency delivery.
Phase 3: Load Testing & Deployment
Stress testing with k6 and Artillery simulating 10x expected traffic peaks. Auto-scaling policies configured and validated. Final deployment with blue-green strategy, real-time monitoring via Grafana dashboards, and SLA guarantees documented in the performance contract.
Phase 1: System Architecture & Technical Specification
Collaborative sprint-zero defining data models, API contracts (OpenAPI 3.1), authentication flows, and component hierarchies. We produce wireframes, database ERDs, sequence diagrams, and a prioritized feature backlog with story-point estimation. Technology stack selection based on performance requirements and team capacity.
Phase 2: Iterative Build & Integration
Two-week agile sprints delivering shippable increments. Backend: RESTful/GraphQL APIs with automated test suites (unit, integration, e2e). Frontend: component-driven development with Storybook documentation. CI/CD pipelines enforced with linting, type-checking, and 90%+ code coverage gates.
Phase 3: Production Launch & Monitoring
Containerized deployment via Docker/Kubernetes with zero-downtime rolling updates. Logging aggregation (ELK stack), error tracking (Sentry), and uptime monitoring configured. Handover includes technical documentation, API reference, contributor guidelines, and a 60-day post-launch support window.
Phase 1: Infrastructure Assessment & Planning
Audit of current deployment workflows, server configurations, and scaling bottlenecks. We analyze cost efficiency, identify single points of failure, and design a target-state infrastructure blueprint with multi-AZ redundancy, auto-scaling policies, and disaster recovery topologies with defined RPO/RTO objectives.
Phase 2: Pipeline Construction & Migration
Terraform/Pulumi infrastructure-as-code provisioning with drift detection. GitHub Actions/GitLab CI pipelines with multi-stage builds, container scanning, and secret management. Blue-green and canary deployment strategies automated with rollback triggers. Database migration scripts with zero-downtime schema evolution.
Phase 3: Operational Readiness & Handover
Runbook documentation for common incident scenarios. Alerting configured via PagerDuty/OpsGenie with escalation policies. Cost monitoring dashboards and reserved instance recommendations. Team training session on infrastructure management with recorded walkthrough documentation.
Phase 1: Contract Design & Schema Definition
API-first design philosophy with OpenAPI 3.1 specifications, GraphQL schema definitions, or gRPC protobuf contracts. We define authentication strategies (OAuth 2.0, API keys, JWT), rate limiting policies, versioning schemes, and error response standards. Interactive documentation portals generated for stakeholder review.
Phase 2: Implementation & Integration
Backend endpoint implementation with input validation, serialization layers, and comprehensive error handling. Third-party integrations (payment gateways, CRM systems, analytics platforms) built with retry logic and circuit breaker patterns. Webhook infrastructure with delivery guarantees and payload verification.
Phase 3: Testing & Documentation Delivery
Contract testing with Pact, load testing for throughput validation, and fuzz testing for edge-case discovery. Complete developer portal with interactive API explorer, code samples in 5+ languages, Postman collections, and SDK generation for primary client platforms. 30-day integration support included.
Phase 1: Schema Analysis & Query Profiling
Deep analysis of existing database schemas,索引策略, and query execution plans. We identify N+1 queries, missing composite indexes, table scan bottlenecks, and connection pool exhaustion. Output includes a normalized schema review, slow query log analysis, and a data architecture optimization proposal.
Phase 2: Restructuring & Migration Execution
Schema migration with version-controlled DDL scripts and automated rollback procedures. Query rewriting for optimized execution paths, materialized view creation for complex aggregations, and partition strategies for large datasets. Connection pooling optimization and read replica configuration for query distribution.
Phase 3: Performance Validation & Monitoring
Benchmarking against baseline metrics with documented improvement percentages. Automated slow query detection with alerting thresholds. Database health dashboards with connection pool metrics, replication lag monitoring, and storage growth projections. Runbook for emergency scaling procedures.
Phase 1: Commerce Architecture & Product Modeling
End-to-end commerce strategy including product catalog taxonomy, pricing rule engines, inventory management schemas, and multi-currency/multi-language support design. Payment gateway integration architecture (Stripe, Mollie, Bizum) with PCI DSS compliance requirements mapped. Checkout flow optimization based on conversion funnel analysis.
