Stack: Next.js, LangGraph, LangSmith, PostgreSQL. 💡 AI goal management coach (Productivity SaaS) - Personal coach PWA built in 3 months. AI breaks goals into milestones, sets reminders, tracks progress. Result: 50% faster task execution for users. 💡 AI platform for insurance brokers (InsurTech) - Modernized the UX of an AI-powered broker tool. Saved 1,500+ hours of broker time annually. Redesigned 10+ core workflows, integrated Stripe credit management and document previews. What I build: - AI chatbots that understand context (not just keywords) - AI agents that execute multi-step workflows autonomously - RAG systems that let AI answer from your company's knowledge base - Generative AI features embedded into SaaS products - AI-powered onboarding, support, and automation flows Tech stack: OpenAI, Anthropic Claude, LangChain, LangGraph, Amazon Bedrock, AWS, Next.js, React, Node.js, Python, PostgreSQL, Stripe Industries: FinTech, EdTech, InsurTech, Healthcare, Manufacturing, Logistics Every project starts with: what problem costs you time or money right now? Then we build exactly what's needed - prototype first, production-ready fast. 🏆 "They value clients and their own time. Excellent time management, understood our needs, set realistic expectations." — Arturs Peha, CSO at Skrivanek Let's talk about your project.

My technical proficiency includes demonstrated expertise in... ➡️ Mobile app language: React Native, Flutter, redux ➡️ Server scripting: PHP (Laravel, Codeigniter, Symphony, Cake, Core PHP) ➡️ JS Framework: NodeJs, ExpressJS, React JS, Angular JS, and Vue JS ➡️ Database: MySQL, PostgreSQL, SQLite, MariaDB, Realm DB, NoSQL, AWS RD, & so on ➡️ Content Management System (CMS): WordPress, Opencart, Shopify, Squarespace, & so on ➡️ Project management: Trello, Basecamp, Slack, JIRA, CI/CD ➡️ Version control and code security: Git (Push and Pull), Bitbucket, & SVN ➡️ Server: AWS, Godaddy, Bluehost, Hostgater (from setup to migration, troubleshooting), Google Cloud, Rackspace, & so on! ➡️ CRM Customization & Integration (via API/Webhooks): Zoho, HubSpot, Salesforce, ZenDesk Simple, predictable, and flexible pricing! I design🎨, build💻, and provide after-delivery support to clients worldwide. Interested? Let's talk 📞 I don’t just apply technical tactics; I also leverage my years of experience to build outstanding web and mobile apps in minimal time and within a reasonable budget.

I build backend systems, APIs, and custom business logic that power real products and operations. A lot of my work happens behind Laravel, WordPress, WooCommerce applications, but the real focus is usually on how systems behave, connect, and scale. Some clients come to me when things start breaking under real usage. Others bring me in earlier to avoid technical debt and build things properly from day one. I'm most valuable not only when the work goes beyond templates and plugins — when there's custom logic involved, integrations between systems, or engineering decisions that affect reliability long-term. Here’s the kind of work I typically take ownership of: ✔ Laravel backend systems and custom application development ✔ API design and integrations (REST, SOAP, webhooks, third-party platforms) ✔ WordPress & WooCommerce custom development beyond plugin limitations ✔ Custom plugin development for business-specific workflows ✔ WooCommerce checkout, pricing, subscription, and order logic ✔ CRM / ERP integrations and data synchronization ✔ Payment gateway and shipping integrations ✔ Multi-system workflows where different platforms need to communicate reliably ✔ Performance, debugging, and stabilization of complex or unreliable systems ✔ AWS deployments, server setup, CI/CD, and production troubleshooting I work comfortably inside existing systems, but I'm equally comfortable starting clean and structuring things properly from the beginning. My approach is straightforward: understand the business logic first, avoid unnecessary complexity, and build systems that are predictable and maintainable. If your project involves APIs, backend workflows, custom WooCommerce behavior, Laravel systems, or integrations between platforms — send me a quick overview of what you're building (or what's not working), and I'll give you a practical direction on the best way forward.
