My approach is simple: understand the real problem first, scope honestly, then build something clean enough to still make sense a year from now. Experience 8+ years across SaaS platforms, e-commerce systems, and AI-integrated web applications. I've built custom CRMs, marketplace platforms, booking and payment systems, and automation pipelines connecting LLMs to real business workflows. Core Stack Frontend: React, Next.js, Vue.js Backend: Node.js, Laravel, Express, Django/Flask where the project calls for it E-commerce/CMS: WordPress, WooCommerce, Shopify, PrestaShop Databases: MySQL, PostgreSQL, MongoDB, Supabase AI/Automation: OpenAI and Anthropic API integration, n8n, LangChain-based agent workflows Payments/Integrations: Stripe, PayPal, Twilio, REST/GraphQL APIs, headless CMS Background Bachelor of Commerce (Marketing) and a BSc in Psychology, which shapes how I think about the projects I build, not just the code, but the user behavior and business logic behind it. Certified in Google Ads Search, Google Analytics, and Microsoft 365 SMB Sales. How I Work Every project starts with real scoping, not a generic quote. If something sits outside my direct experience, I say so upfront and propose a way to bridge it responsibly, whether that's a smaller first milestone to prove capability or an honest caveat before we commit. I'd rather lose a bid on transparency than win one on an inflated claim and disappoint a client six weeks in. What You Get Clean, maintainable code. Realistic timelines. Direct communication throughout, no disappearing between milestones. And a developer who treats "I don't know that platform yet, but here's how I'd approach learning it responsibly" as a legitimate answer, not something to hide. If it's technically achievable, I can build it, and I'll tell you plainly if it isn't. menos -

Our work sits across two areas that are increasingly coming together: modern software engineering and applied AI. We help businesses build new digital products, modernise existing systems, connect fragmented platforms and introduce AI where it can improve how people work, make decisions or handle information. Our AI work includes Generative AI, RAG, intelligent agents, document understanding, workflow automation, computer vision and AI-assisted decision systems. We focus beyond the model itself: the data it uses, how it integrates with existing applications, how outputs are validated, and how the solution operates reliably within the business. Alongside AI, we design and develop web, mobile and enterprise applications covering operational workflows, ERP and CRM systems, transaction platforms, dashboards, reporting, integrations, data processing and cloud modernisation. Our experience spans telecom, logistics, manufacturing, healthcare, retail, finance and education. This includes enterprise platforms handling high transaction volumes, complex operational workflows, payments, inventory, documents, customer operations and third-party integrations. Our team brings together AI architects, enterprise architects, full-stack engineers, mobile developers, data specialists and cloud engineers. Depending on the requirement, we can take responsibility for an end-to-end build or work within an existing product, codebase and engineering environment. We are particularly useful when the requirement sits between business operations and technology: where understanding the workflow, data, integrations and existing systems matters as much as writing the software. If you are building a new product, modernising an existing platform or evaluating where AI can create practical value, we can review the requirement and help determine the right technical direction before unnecessary complexity or cost is introduced. menos
