Your trusted partner for data engineering, Shopify development, fullstack products, and GenAI development.
From Poland With Dev is a 100+ person software agency helping US and EU businesses build and scale digital products since 2015. This post walks you through our four core service areas – Data Engineering & Analytics, Shopify Development, Fullstack Web & App Development, and Generative AI & LLM Solutions – with project highlights and links to each service page.
Whether you're a growing ecommerce brand, a data-driven enterprise, or a startup building your first digital product, finding a reliable tech partner can be the difference between stalling and scaling.
At From Poland With Dev, we've spent over a decade working closely with US and EU clients. 98% of our projects come from returning clients or personal referrals.
We cover four interconnected service areas: data engineering and analytics, Shopify development and optimization, fullstack web and app development, and generative AI and LLM solutions. Below, we'll give you a close look at each: what we do, who we've done it for, and what you can expect when you work with us.
Modern businesses generate more data than ever, but raw data alone doesn't drive decisions. Our Data Engineering & Analytics team – with specialists like Patryk (Senior Data Analyst & BA) and Marlena (Data Analyst) – helps you collect, process, and activate that data across the full lifecycle: from ingestion and transformation to machine learning and business-ready dashboards.
As Marlena put it based on her experience working with eCommerce clients: if you try to track everything, you risk using almost nothing. A good dashboard delivers the right data to the right people. We work on scalable, cloud-native platforms on AWS, GCP, and Azure, using tools like dbt, Apache Spark, Airflow, Snowflake, BigQuery, and Databricks – whether you need a modern data warehouse, a real-time analytics pipeline, or a Marketing Mix Model to optimize your ad spend.
For Lucchese, we processed hundreds of millions of transaction records across 60+ source tables, built 40 Tableau dashboards, automated 30 daily reports, and developed an advanced Marketing Mix Model trained on 10+ data sources using Amazon SageMaker.
For a B2B intent data platform, we built large-scale data pipelines powering AI-generated insights and intent-based targeting for programmatic advertising – using a stack that included AWS, Apache Airflow, PySpark, Snowflake, and Power BI.
Beyond the platforms themselves, we also offer data strategy workshops, BI modernization, ML/DS model development, and ongoing team enablement. If your data is sitting in silos, this is where we start untangling it.

Ecommerce is competitive, and your Shopify store needs to work harder than ever – faster, smarter, and built for growth. Our Shopify Development & Optimization team brings deep platform expertise to every engagement, from custom theme builds and Shopify Plus implementations to complex ERP integrations and AI-ready commerce architecture.
We know what makes shoppers convert. It's something Joanna, one of our Frontend Developers, sees up close on every project – from the way users move through a checkout flow to how the right analytics setup can reveal exactly where customers come from and what makes them buy.
But great frontend work is only half the picture. As Piotr, our Senior Fullstack Developer, puts it: the team regularly goes beyond Shopify's native capabilities, building custom backend solutions – from Shopify Functions and cart transforms to fully custom bundle logic – that give brands the flexibility the platform alone can't always offer.
Jan, our Senior PM & Frontend Developer, makes sure those moving parts come together cleanly, keeping stores stable even during the highest-traffic moments – Black Friday, Cyber Monday, major product launches.
We know what makes shoppers convert. We apply UX and CRO best practices across every customer journey, with deep expertise in keeping stores stable and performant during high-traffic moments like Black Friday/Cyber Monday (BFCM) or major product launches.
For Lucchese, a luxury Western fashion brand, the team delivered one of their most comprehensive engagements to date. Dawid and colleagues on the backend drove a major architectural effort – a serverless migration, deep NetSuite ERP integration, automated E2E testing, and a significant cleanup of technical debt – creating a more scalable and future-proof foundation. Alongside that, the team delivered a full end-to-end storefront redesign, a lightweight custom A/B testing framework, accessibility improvements aligned with WCAG and ADA standards, omnichannel customer journeys, custom wishlist and save-for-later functionality, a bespoke customer dashboard, and advanced promotional mechanics like Gift With Purchase. All of it built to push well beyond what Shopify offers out of the box.
For Echelon Fit, a global fitness equipment brand, we optimized complex discount and membership logic across four Shopify stores, upgraded checkout using Shopify Functions, and integrated NetSuite for inventory and order synchronization.
For Clevr Blends, a functional wellness beverage brand, we focused on subscription-flow optimization, CRO improvements across the PDP and cart, and resolving revenue-critical bugs.
For Flaus, the eco-friendly oral care brand behind the world's first electric flosser, Piotr and the team built reusable PDP templates with more flexible sitewide logic, supported subscription reliability via Stay AI, helped prepare the store for a Shark Tank appearance, and implemented SEO and structured data improvements alongside ongoing campaign and BFCM support.
If your Shopify store needs a performance upgrade, integrating with your existing tools, or scaling to the next level, our experts are one email away.
Our Fullstack Development team covers the full stack – frontend, backend, integrations, and infrastructure – at every stage of your product journey.
We use modern technologies including React, Next.js, Node.js, TypeScript, PostgreSQL, GraphQL, and AWS, and we work across the entire product lifecycle: from early architecture decisions through to launch, scaling, and beyond.
As Mariusz, our Lead Fullstack Developer, puts it: the team most often delivers the full package – frontend, backend, integrations, and infrastructure all together – but just as comfortably steps in for standalone work, whether that's a custom frontend, a backend service, or a tricky integration like connecting Shopify to a bespoke ERP system. ETL pipelines fall into that category too: they might sit at the edge of data engineering, but building them reliably takes serious fullstack craftsmanship.
Adam, our Tech Lead, shapes the early architecture decisions that determine whether a product stays clean and scalable as it grows – and from there, engineers like Konrad take over the build across the full stack. Quality is baked in throughout: Kamil, one of our QA Engineers, makes sure critical journeys are tested and release-ready before anything ships.
For a fintech employee wellness platform, Mariusz and the team built a US-market application integrating Plaid for secure, real-time bank account connectivity, developed a financial insights engine with transaction analysis and goal tracking, and delivered an employer-side dashboard with aggregate workforce financial data.
For a sports technology platform for baseball recruitment and team management, the team built a fullstack solution spanning two application modules – including an ETL pipeline aggregating player data from multiple sources, an AI-powered natural language search engine, and a custom codegen layer bridging GraphQL and REST APIs.
From SaaS platforms and data-intensive applications to complex integrations and ETL pipelines, we build with scalability and long-term ownership in mind.
AI is only valuable when it works inside your business. Our Generative AI & LLM team builds production-ready AI systems grounded in your real data: RAG pipelines connected to internal knowledge bases, custom AI assistants and chatbots, intelligent document processing, natural language interfaces for querying data, and vision and speech AI solutions.
Łukasz, our Head of Development, oversees that the work is always grounded in genuine business needs rather than AI for its own sake – the goal is practical systems that slot into how your teams already work. On the research and engineering side, Piotr and colleagues like Dawid and Aleksandr handle the harder technical problems: model optimization, hardware-accelerated inference with tools like vLLM and Nvidia Triton, and building pipelines that connect AI outputs to trusted, business-specific data.
We integrate with your existing platforms – whether that's Snowflake, Databricks, BigQuery, or a custom data warehouse. We also handle the infrastructure side: LLM serving optimization, hardware-accelerated formats like TensorRT, and scalable cloud deployment across AWS, Azure, and GCP.
The team's work with ShareTheBoard shows what production-grade AI can look like in practice. ShareTheBoard is an award-winning EdTech platform that uses real-time computer vision to digitize, enhance, and transcribe handwritten whiteboard content – making classrooms more accessible for students with visual impairments, ADHD, or dyslexia. The team built a custom semantic segmentation model that runs directly in the browser without cloud GPUs, adaptive model variants optimized for different hardware setups including low-spec devices, and a full platform available both in-browser and as a Windows desktop application. The impact was very real: improved learning outcomes for approximately 20% of students with learning differences, reduced infrastructure costs, and increased engagement in hybrid and remote classrooms. ShareTheBoard went on to win the 2026 SXSW EDU Impact Award in the Launch Startup Competition.
We know what practical, production-grade AI looks like – and we will gladly help you integrate it into your business.
