Artur L.

With over 8 years of experience as a Technical Architect, I build intelligent, scalable systems that bridge the gap between custom backend development (Node.js) and the Salesforce platform. I don't just build features; I architect robust, integrated solutions that become the foundation for real business growth for SaaS and FinTech companies. My unique value lies in my ability to operate at two levels: as a backend architect creating complex SaaS platforms from the ground up, and as a certified Salesforce expert seamlessly embedding those systems into core business processes. If you need a technical partner who understands how to make technology drive revenue, we should talk. 𝗠𝘆 𝗖𝗼𝗿𝗲 𝗘𝘅𝗽𝗲𝗿𝘁𝗶𝘀𝗲: 𝗔𝗜 & 𝗜𝗻𝘁𝗲𝗹𝗹𝗶𝗴𝗲𝗻𝘁 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 I build smart solutions by integrating APIs like OpenAI (GPT-4) and LangChain to develop AI chatbots, automate content generation, and implement RAG pipelines. I specialize in creating AI-powered systems for Salesforce, including Twilio-based voice bots for lead qualification and custom CTI solutions that boost sales team productivity. 𝗖𝗿𝗼𝘀𝘀-𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺 𝗔𝗿𝗰𝗵𝗶𝘁𝗲𝗰𝘁𝘂𝗿𝗲 (𝗦𝗮𝗮𝗦 & 𝗦𝗮𝗹𝗲𝘀𝗳𝗼𝗿𝗰𝗲) I design and build architecture from scratch, whether it's a multi-tenant SaaS platform using Node.js (NestJS) or a commercial AppExchange application. I manage the full lifecycle of creating managed packages (2GP), including successfully passing the official Security Review. 𝗙𝗶𝗻𝗧𝗲𝗰𝗵 & 𝗦𝗲𝗰𝘂𝗿𝗲 𝗣𝗮𝘆𝗺𝗲𝗻𝘁 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻 I have deep experience integrating payment gateways like Stripe (including Subscriptions & Connect) and PayPal. I develop automated billing logic and build secure financial workflows for SaaS services and marketplaces, fully integrated with Salesforce. 𝗔𝗱𝘃𝗮𝗻𝗰𝗲𝗱 𝗖𝗥𝗠 & 𝗠𝗮𝗿𝗸𝗲𝘁𝗶𝗻𝗴 𝗔𝘂𝘁𝗼𝗺𝗮𝘁𝗶𝗼𝗻 I go beyond standard configurations. I develop custom Journey Builder activities (Marketing Cloud), interactive email blocks (AMPscript, LWC), and complex integrations that deliver a truly personalized customer experience. 𝗖𝗹𝗼𝘂𝗱 𝗜𝗻𝗳𝗿𝗮𝘀𝘁𝗿𝘂𝗰𝘁𝘂𝗿𝗲 & 𝗗𝗲𝘃𝗢𝗽𝘀 I ensure your application is reliable and scalable. I manage the full deployment lifecycle using Docker, Kubernetes, and AWS (ECS, EKS, Lambda), and I build robust CI/CD pipelines with GitHub Actions for both Node.js applications and Salesforce (Salesforce DX). 𝗧𝗲𝗰𝗵𝗻𝗼𝗹𝗼𝗴𝘆 𝗦𝘁𝗮𝗰𝗸: 𝗕𝗮𝗰𝗸𝗲𝗻𝗱: Node.js, NestJS, TypeScript, Express.js, Microservices, REST/GraphQL API 𝗦𝗮𝗹𝗲𝘀𝗳𝗼𝗿𝗰𝗲 𝗣𝗹𝗮𝘁𝗳𝗼𝗿𝗺: Apex, LWC, Aura, Visualforce, SOQL, Flow Builder, Sales Cloud, Service Cloud (Voice), Marketing Cloud (Pardot), Experience Cloud 𝗗𝗮𝘁𝗮𝗯𝗮𝘀𝗲𝘀: PostgreSQL, MongoDB, Redis, MySQL, AWS DynamoDB Cloud & DevOps: AWS (ECS, EKS, Lambda, S3), Docker, Kubernetes, Heroku, Salesforce DX, CI/CD, GitHub Actions 𝗞𝗲𝘆 𝗜𝗻𝘁𝗲𝗴𝗿𝗮𝘁𝗶𝗼𝗻𝘀: OpenAI API, Twilio, Stripe, PayPal, Shopify, Salesforce, Telegram Bot API, DocuSign 𝗟𝗼𝗼𝗸𝗶𝗻𝗴 𝗳𝗼𝗿 𝗮 𝗰𝗼𝗺𝗽𝗹𝗲𝘁𝗲 𝗽𝗿𝗼𝗷𝗲𝗰𝘁 𝘁𝗲𝗮𝗺? Beyond solo development, I can assemble and lead a dedicated team of trusted freelance professionals (front-end, UI/UX, QA) to deliver a complete, end-to-end product. You get the quality of a boutique agency with the flexibility and speed of a freelancer. 𝗥𝗲𝗮𝗱𝘆 𝘁𝗼 𝗯𝘂𝗶𝗹𝗱 𝗮 𝘀𝗰𝗮𝗹𝗮𝗯𝗹𝗲, 𝗽𝗿𝗼𝗱𝘂𝗰𝘁𝗶𝗼𝗻-𝗿𝗲𝗮𝗱𝘆 𝗮𝗽𝗽𝗹𝗶𝗰𝗮𝘁𝗶𝗼𝗻? 𝗟𝗲𝘁'𝘀 𝘀𝗰𝗵𝗲𝗱𝘂𝗹𝗲 𝗮 𝗯𝗿𝗶𝗲𝗳 𝗰𝗮𝗹𝗹 𝘁𝗼 𝗱𝗶𝘀𝗰𝘂𝘀𝘀 𝘆𝗼𝘂𝗿 𝗽𝗿𝗼𝗷𝗲𝗰𝘁.
