Hire the Best Front-End Developers
in Lithuania

My name is Mykolas, and I would love to help you with any of your Shopify, WordPress, or general web development needs. Be it custom theme development, minor fixes to the site, or conversion rate optimization efforts - you can count on me for that! Clear communication between the client and freelancer is key to success. That is why I always go above and beyond to clearly define the scope of any new project and maintain open communication with clients throughout the project. And most importantly, I always strive to establish a longer-term working relationship, rather than viewing a gig as a one-time transaction. So, if that's what you're looking for as well, we're a good match!

Most "AI developers" can wire ChatGPT to a database. I build agent systems that survive in production — orchestrators with retries, state management, observability, and cost control. 6+ years as a Software Engineer, now full-time System Engineer building AI-driven SaaS at Mplus (DE), available for select Upwork projects. I'm Martin — Top Rated, 100% JSS, 5★ across all closed contracts. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ WHAT I ACTUALLY SHIP → Production AI agents that don't fall over Stateful agents with retries, tool routing, error recovery, observability, and cost control — not a demo that breaks on the second user. → Custom orchestration when frameworks aren't enough LangGraph and Claude MCP where they fit. Custom architectures when your workflow doesn't fit a framework. I design the agent system — I don't just bolt one together. → Claude & OpenAI integrations done seriously Anthropic Claude with Tools and MCP, OpenAI Assistants & Agents SDK, function calling, structured outputs, streaming, hybrid model routing for cost/latency trade-offs. → Full-stack delivery around the agent Python for the AI layer, Node/TypeScript for APIs and web. Postgres, pgvector, queues, webhooks. The agent isn't the product — the system around it is. I build both. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ CURRENT WORK (gives you a sense of what I do day-to-day) System Engineer at Mplus (DE) — building an AI-driven SaaS for residential energy efficiency analysis: B2C assessment tools plus a B2B contractor marketplace. Real users, real production. Past: R&D monitoring system for a Tel Aviv pharmaceutical client. High-traffic B2C platform with 1.2M+ users at Enkonix (AWS, message queues, cross-team integrations). ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ MY STACK AI Layer: Anthropic Claude (Tools, MCP), OpenAI Assistants & Agents SDK, LangChain, LangGraph, custom orchestration Backend: Python (primary), Node.js, TypeScript, FastAPI, Express Data: PostgreSQL, pgvector, Redis, MongoDB, Supabase Infra: AWS, Vercel, Docker, queues, webhooks, observability Web: React, Next.js (when the agent needs a UI around it) ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ HOW I WORK Day 1-2: Discovery call. I map your agent's workflow, edge cases, and failure modes BEFORE writing code. Week 1: First working agent loop in staging — you run real inputs against it. Ongoing: Async updates, weekly demo, observability dashboard so you see what the agent is doing. Handoff: Clean repo, README, evals, deployment docs, runbook for common failures. ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ NOT A FIT IF YOU NEED: ✗ "Build me a ChatGPT clone" — that's a wrapper, not an agent ✗ Pure prompt engineering with no system behind it ✗ Trading bots, gambling, or crypto-trading AI ✗ The cheapest bid — I'm not it ━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━━ If you've hit reliability walls with n8n + GPT, or you're past the prototype stage and need a real system — send me the brief. I'll come back with a scoped architecture plan, not a generic pitch. — Martin
