UI UX Designer, product designer, and graphic designer with $100K+ earned,
2,186 hours, and 100% Job Success on Upwork. Worked with NovoNordisk, AI based B2B cybersecurity startup, NexQloud, raised more than $5M+ investments.
Over the years as a UI UX designer and UIUX designer, I've learned that great digital products are never just about aesthetics - they are about solving real problems, reducing friction, and turning users into customers.
🎯 What I bring as a UI UX Designer, Graphic Designer, and Product Designer:
✔️ Strategy first, design second. As a UI UX designer and product designer, I begin every project with research - user personas, competitor analysis, and conversion rate optimization - before opening Figma. Whether working as a saas designer on a B2B dashboard, a landing page designer on a high-traffic page, or a web designer on a full website design, the goal is always interfaces that convert and grow. As a uiux designer, saas designer, and product designer, I treat every layout decision as a business decision. A great uiux designer always asks "does this convert?" before "does this look good?"
✔️ Figma is my primary tool as a figma designer. As a figma ui designer and uiux designer, I build design systems with reusable components, figma ui ux tokens, and developer-ready specs. I handle figma to react, figma to webflow, figma to wordpress, figma to shopify, and figma to next - so nothing is lost between design and development. A strong figma designer understands that ui/ux figma precision separates beautiful mockups from products that ship. My ui/ux figma approach bridges strategy and execution - and every ui/ux figma file I produce as a web designer is handoff-ready. Good ui/ux figma work makes a figma designer genuinely useful to a development team.
✔️ As a graphic designer and web designer, my visual craft goes beyond UI. I create logo design, brand identity, social media graphic designer assets, and motion graphic designer content. Good graphic designer work builds trust before users read a word - as a product designer and graphic designer, every visual decision is a trust signal.
✔️ Web design is where strategy and craft meet. As a web designer, website designer, and landing page designer, I design across wordpress website design, wix web design, shopify website design, and squarespace website design — grounded in conversion rate optimization. As a landing page designer, I think in scroll depth, CTA placement, and user intent. Every website design I produce as a website designer is built to convert. A landing page designer without conversion rate optimization is just decorating. As a ui/ux web designer and website designer, every website design decision is backed by conversion rate optimization data - and every website designer knows that data-driven web design outperforms opinion-driven web design every time.
✔️ As a wordpress designer and web developer, I build SEO-optimized WordPress websites - from wordpress designer theme builds and wordpress woocommerce designer stores to full website design systems. As a wix web designer and website designer, I support teams who need manageable website design without heavy development overhead.
✔️ SaaS demands more than good design. As a saas designer and uiux designer, I design ui ux dashboard systems, role-based navigation, and data-heavy interfaces that feel effortless. My ui/ux figma work for SaaS consistently improves onboarding and retention. Every saas designer decision I make reflects real user behaviour.
✔️ Mobile is a different context. As a mobile app ui ux designer, I design iOS and Android experiences with thumb-zone navigation - delivering figma app design files developers can build from immediately.
📊 Results:
🔶 UI UX Designer, Logistics SaaS: 200% order efficiency, 50% error reduction, 70% less manual work.
🔶 Graphic Designer & UI UX Designer, E-commerce: 15% revenue up, 30% less cart abandonment.
🔶 Mobile App UI UX Designer, Health App: 2x retention, 3x faster onboarding.
As a website designer, saas designer, landing page designer, and figma designer who applies conversion rate optimization, ui/ux figma thinking, and product designer discipline to every engagement - I bring the full picture. Nothing gets lost between the brief and the browser.

I build and migrate CRMs that stop leaking deals — 9+ years across HubSpot, Salesforce, Method CRM, and integrated marketing stacks. Certified by HubSpot Academy (Marketing & CRM, 2021) and Shopify Partners (Developer, 2022).
My focus: HubSpot migrations, AI×CRM workflows, and Shopify app builds for B2B SaaS and DTC operators who want their tech stack to actually run their business.
How I work:
(1) audit your current CRM and integration setup — what's broken, what's missing, what's redundant.
(2) map a 30/60/90-day migration plan with clean lifecycle stages, deal pipelines, and lead scoring rules.
(3) build the integrations — HubSpot ↔ Salesforce, Shopify ↔ HubSpot, Stripe webhooks, custom API connectors, n8n and Make com automation.
(4) ship with documentation and a dashboard that proves the work. Done = HubSpot deal-velocity report, GA4 event attribution, and a Looker Studio panel that survives the next handoff. Stack: HubSpot Operations Hub, Salesforce, Shopify, Klaviyo, Kit (ConvertKit), Stripe, n8n, Make com, Zapier, Python (FastAPI), Node.js, OpenAI API, LangChain, Pinecone.
Recent wins on Upwork: $4,000 Method CRM → HubSpot migration strategy with custom-object mapping and lifecycle automation across Sales and Marketing pipelines. $4,000 Shopify app shipped end-to-end (llms.txt generator, JSON-LD schema, AI FAQ generator, AI feed). $1,000 Kit (ConvertKit) hands-on training for a marketing team to run their own list. If your sales team manually copies deal data from emails into spreadsheets, your CRM lifecycle stages are inconsistent, or your AI integration ideas are stuck on whiteboards — that is the work I do.
Send me a brief for your CRM migration, marketing automation rebuild, or AI×CRM integration project, whether it is a 2-week sprint or a multi-month rebuild. What is the single workflow eating most of your team's week right now?

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.

I am a Java developer with over 14 years of experience building full stack applications, enterprise systems, and SaaS platforms 🚀
My focus 🎯 is on using Java, Spring Boot, React.js, PostgreSQL, and AWS to deliver reliable, scalable software. As a Java developer, I have delivered dozens of projects across industries and use cases.
My backend work is built entirely with Java. I create secure APIs and microservices using Spring Boot. I have deep experience in system architecture, backend performance, and database design. Every project I take as a Java developer is written with clean, maintainable Java code. I know how to structure services that scale.
As a Java backend developer, I have built and maintained systems for high-load traffic, third-party integrations, and complex business logic. I manage full backend pipelines, from architecture and development to deployment and monitoring. I use Spring Boot and follow best practices every Java developer should apply.
I also work as a full stack Java developer, connecting Java backends with React.js and JavaScript frontends. I create dashboards, user interfaces, and admin tools that are fast, stable, and fully integrated. I know how to deliver full stack features without bottlenecks.
I have led teams as a senior Java developer, mentoring other developers, reviewing Java code, and improving team performance. My clients rely on me not just for development, but also for decisions about architecture, data structure, and deployment strategy. As a Java developer, I care about the full picture.
In most projects, I take the role of a Java spring developer and own the backend infrastructure. I work with Docker, PostgreSQL, REST APIs, and cloud services. I often work independently, taking full responsibility for both backend and frontend parts as a full stack developer.
Being a professional Java developer means I deliver production-ready code, meet deadlines, and communicate clearly. I work well with teams or as a solo contributor. My background as a Java backend developer and Java spring developer allows me to adapt to different project needs.
If you need a Java developer who can work on backend systems, full stack features, or cloud-based platforms, I am ready to help. Whether you need a senior Java developer, a Java backend developer, or a reliable full stack Java developer, I can take your project from idea to production.
🛠️ Core Skills:
- Java developer
- Java backend developer
- Full stack Java developer
- Java spring developer
- Spring Boot microservices
- React.js and JavaScript
