Software development and integration services
Full-spectrum software development, system integrations and AI services.
Pascual Solutions is a studio specializing in demanding software projects: custom development, system integrations, Shopware 6 e-commerce and AI automation. We cover the full lifecycle — from discovery and technical spec through launch, monitoring and long-term maintenance.
Custom software development
Web apps, SaaS products and internal tools built on proven technologies. Focus on performance, security and code maintainability — the codebase stays yours, documented and covered with tests.
What you get
- An application with full source code in your repository
- Technical documentation and an operations runbook
- Automated tests and a CI/CD pipeline on GitHub Actions / GitLab CI
- Monitoring, alerting and a backup strategy
- An SLA for maintenance after launch
Tech stack
- TypeScript
- Next.js
- Node.js
- Python
- PostgreSQL
- Redis
- Docker
- Kubernetes
Custom web applications
Bespoke applications when no SaaS can model your process. Next.js + TypeScript on the front, Node.js or Python on the back, PostgreSQL as the primary store. Server-side rendering, authentication, role-based access and audit logging baked in from day one.
SaaS products
Multi-tenant architecture, billing (Stripe / Paddle), subscription management, role and permission systems, an admin panel for support. Scales from pilot customer to thousands of paid users without rewriting the foundations.
Internal tools and admin panels
Dashboards for operations, warehouse, customer support and finance. CRUD interfaces over your existing database, reports, exports, roles and 2FA. We replace the Excel chaos and the manual steps.
API development
Production-ready REST, GraphQL, gRPC and webhook APIs: OpenAPI documentation, versioning, rate-limiting, authentication (JWT, OAuth2, API key), idempotency and monitoring. Ready to integrate with partners and mobile apps.
Microservices and scalable architecture
When the monolith no longer carries the load — domain-driven decomposition, message bus (RabbitMQ, Kafka, NATS), observability (OpenTelemetry, Grafana), Docker containerization and deploys on Kubernetes or Nomad.
E-commerce on Shopware 6
Shopware 6 is our default e-commerce platform for B2C, B2B and multi-brand projects. We launch new stores, migrate from Magento or WooCommerce, build custom plugins, and integrate with ERPs and banks.
What you get
- A stable Shopware install with staging and production environments
- A CI/CD pipeline for plugin deploys with no downtime
- Live integrations with ERP, banks and couriers
- A performance budget and recurring audit reports
- Monthly support and feature delivery
Tech stack
- Shopware 6
- PHP 8
- Symfony
- Twig
- Vue.js
- Varnish
- Redis
- MariaDB
Shopware 6 implementation
Greenfield implementations: edition selection (Community / Rise / Evolve), data model, categories, attributes, variants, sales channels and payment strategy. Theme setup, checkout flow, SEO and conversion measurement.
Custom plugin development
Plugins that respect the Shopware ecosystem: hooks on the event system, Symfony services, Twig templates, REST and Store API extensions. Coupon and bundle logic, B2B price lists, custom checkout steps, ERP connectors.
Migrations to Shopware 6
Migrations from Shopware 5, Magento 1/2, WooCommerce, PrestaShop and custom platforms. Mapping products, categories, customers, orders and SEO redirects with validation and gradual traffic switching.
Performance audit and optimization
Detailed audit of Core Web Vitals, database (slow queries, indexes), HTTP cache strategies (Varnish, Redis), front-end optimization (lazy loading, image pipeline, critical CSS) and Lighthouse score targets for PDP / PLP / Checkout.
Multi-store and multi-currency
Multiple brands, regions and languages in one admin instance: sales channels, locale variants, currency rules, EU tax rules, consistent catalog and centralized inventory.
System integrations
We specialize in integrations where off-the-shelf connectors fail — local ERPs, banking platforms, multi-channel systems and legacy systems that speak SOAP, FTP or XML. Our goal is a system that runs 24/7, not a project delivered once and left to rot.
What you get
- A map of every integration touchpoint and the data flowing between systems
- Idempotent services with retry, dead-letter and replay logic
- Monitoring, alerting and SLAs on critical integrations
- Documented data contracts between systems
- A migration plan for when an upstream system changes
Tech stack
- Node.js
- Python
- RabbitMQ
- Kafka
- PostgreSQL
- Redis
- Temporal
- OpenTelemetry
ERP integrations (Pantheon and others)
Direct sync of products, variants, stock, orders, invoices and customers. Real-time webhooks where supported, batch sync where not. Auto-posting, idempotency and replay logic for outages.
Banking integrations
Banca Intesa, NLB, Raiffeisen and others: e-commerce gateway, wire payments, automatic statement parsing (reconciliation), POS systems and SWIFT/SEPA files. PCI-DSS-aware design — we never store the PAN.
API integrations
REST, GraphQL, SOAP and webhook integrations with marketplaces (Amazon, eMAG), couriers (DHL, GLS, local post offices, AKS, BEX), accounting systems and CRM platforms.
Automation pipelines
Event-driven workers, scheduled jobs and message queues that connect systems without tight coupling. Retry strategies, dead-letter queues and alerting when something breaks.
CRM integrations
Bidirectional sync between CRM (HubSpot, Pipedrive, Salesforce) and shop / billing systems. Lead scoring, automated follow-up, segmentation and export to marketing tooling.
Quality assurance and testing
QA is not a phase before release; it is part of every iteration. We set the testing strategy, automate the critical user journeys and put quality gates in CI/CD so bugs do not reach production.
What you get
- A testing strategy matched to project risk
- A test pyramid covering critical user flows
- A CI pipeline that blocks merges on red
- A reproducible performance baseline with regression alerts
- A manual runbook for high-load seasons
Tech stack
- Playwright
- Cypress
- Vitest
- Jest
- Postman
- Newman
- k6
- JMeter
Manual and exploratory testing
Smoke tests before release, regression checklists, exploratory sessions for risky changes, and UAT support with the client team.
Test automation
Playwright and Cypress for end-to-end, Vitest / Jest for unit and integration. Resilient selectors, parallel execution, and reports with screenshots and videos for failed runs.
API testing
Postman / Newman collections, contract tests (Pact), schema validation. Coverage of rate-limiting, authentication and idempotency for both public and internal APIs.
Performance and load testing
k6 and JMeter scenarios for peak traffic, soak tests for memory leaks, application and database profiling, baseline metrics before and after each optimization.
QA in the CI/CD pipeline
Quality gates: lint, type-check, unit, e2e, security scan, lighthouse audit. Before a PR hits main, every check must pass. Fewer regressions, faster reviews.
Performance digital marketing
Marketing campaigns tied to a real business outcome — orders, leads, signups. We set up measurement, build campaigns and iterate on data instead of opinion.
What you get
- Tracking that survives Apple ITP and the cookie crackdown
- Campaigns structured to scale, not just to test
- Monthly reporting with clear next-cycle recommendations
- Creative assets and landing-page experiments
- A predictable Cost per Acquisition on the core campaigns
Tech stack
- Google Ads
- Meta Ads
- GA4
- GTM
- Looker Studio
- Klaviyo
- Brevo
Google Ads (Search, Shopping, Performance Max)
Structured Search campaigns with SKAG / theme-based ad groups, Shopping and Performance Max for e-commerce, remarketing and YouTube for awareness. Negative keywords and creative A/B tests as a continuous process.
Facebook and Instagram Ads
Conversion campaigns with Pixel + Conversions API setup, custom and lookalike audiences, dynamic product ads against the Shopware catalog, and creative variations tested per cohort.
SEO optimization
Technical audit (Core Web Vitals, indexability, structured data, hreflang), content strategy and internal linking, relevant backlinks via partnerships and guest posting.
Conversion tracking
GA4, GTM (web + server-side), Conversions API, enhanced conversions, end-to-end attribution from first touch to order. Looker Studio dashboards for stakeholders.
Marketing automation
Email (Klaviyo, Brevo, ActiveCampaign), retargeting and CDP setup. Welcome series, cart abandonment, post-purchase, win-back — segmented on real shop behavior.
UI/UX design and web development
Design that ships in code and is measured in conversion. We deliver brand identity, design systems, marketing sites and landing pages focused on a specific conversion — not on awards.
What you get
- A consistent brand and design system in code
- Sites with Lighthouse 95+ and a clear CTA flow
