Hire the Best TypeScript Developers
in Greece

Thank you for taking the time to explore my profile. Here's a quick overview of why I'm the right fit for your project needs: I bring a wealth of experience as a Javascript/Typescript/Blockchain engineer, with specialized skills in React, Next.js, Node.js, Tailwind CSS, SaSS, Redux, MongoDB, and Web3 for robust full-stack development. My expertise also extends to mobile app creation using React Native and Flutter. Known for my positive outlook and unwavering energy, I excel in maintaining clear communication in every scenario. Have designs ready in Figma, Adobe XD, InVision, etc.? I'm adept at turning those into flawlessly coded implementations. My journey includes co-founding and managing eclubs, a startup that has reached thousands of users in Athens. Additionally, I contributed significantly to another application that successfully secured $200K in funding, showcasing my ability to lead projects from idea to investment. My roles have varied across the board, from Project Owner on diverse tech ventures, CTO of two startups (AI), to Tech Lead on an NFT marketplace. These experiences have equipped me with a unique blend of skills, enabling me not just to code, but to strategically align technological solutions with business objectives. While I'm ready to align with your vision, I'm also prepared to suggest alternative strategies when I see an opportunity for improvement. How I Can Assist: - Crafting state-of-the-art web (using JamStack/React) or mobile apps, selecting the best technology (Flutter or React Native) based on your project's requirements. - Revitalizing, updating, or troubleshooting your existing applications. - Offering strategic advice and proposing potential enhancements to your project, drawing from my extensive background. - Converting your design concepts (in Figma, Adobe XD, InVision, etc.) into pixel-perfect code or enhancing existing designs. What to Expect Working with Me: 1) Constant availability and swift responses. 2) Immediate project commencement and rapid execution. 3) Full commitment to your project. 4) Deep industry insights. 5) Broad programming knowledge and experience in navigating the startup ecosystem. I'm eager to discuss how I can contribute to your app or business. Let's schedule a time for a video call or chat to better understand your project's needs, how I can cover all development aspects, or dive deeper into discussions about your project's inception, growth, or enhancements.

I'm a senior software engineer based in Athens with 10+ years shipping production systems. I run a small studio (The Gyld) and take on a limited number of direct engagements per quarter. I specialize on three things, all related: 1. Framework migration audits. Vue 2 → Vue 3 AngularJS → modern stacks React class → hooks Webpack → Vite CRA → Next.js. Two-week fixed-scope audit, per-component effort estimate with a confidence interval, risk register, and an ordered migration plan you can hand to a CFO. From there I can either hand off to your team, or execute with my studio. 2. Inherited codebase rescue. You took over a codebase you didn't choose, original team is gone, tests are missing, deploys are scary. I do a two-week diagnostic that gives you an honest rewrite-vs-refactor verdict, a prioritised stabilisation roadmap, and the parts that ship revenue first. No "let's rewrite everything" theatre. 3. Production LLM systems. GPT/Claude features that survive real users. RAG with evals, prompt versioning, cost ceilings, hallucination containment, model routing, and the boring infrastructure your support team won't hate. I work alongside prompt engineers, not instead of them. Stacks I work in daily: TypeScript · React · Vue 3 · Next.js · Node.js · Python · Django · FastAPI · PostgreSQL · React Native · OpenAI / Anthropic APIs · LangChain · vLLM · Vite How I work: - Written-first. You'll get notes, diagrams and plans before I touch code. - Honest scoping. If your problem is smaller than you think, I'll tell you. - Async-friendly. EU hours, but I overlap meaningfully with US East and APAC. Engagement shapes: - 2-week migration audit (fixed scope, fixed price) - 2-week codebase rescue diagnostic (fixed scope, fixed price) - 4–12 week production LLM build - Monthly retainer for architecture, reviews and senior pair-programming - Hourly for short-scope work, debugging, second opinions If you're a founder, CTO, or engineering lead with a codebase that needs senior judgement, not just more hands, message me. I'll tell you within 48 hours whether I'm the right fit.

Hey, Stratos here👋 Give me something to build and I'll build it so it works for you 24/7. That's my promise! → Migrated 35,800+ records into a client's live CRM. Zero errors, zero skipped. → Built an AI voice agent that replaced ~€18k/yr of appointment-setting labor for a marketing agency. → 55+ automations shipped in production. Top Rated, 100% Job Success, 5.0 on every project. View my portfolio below, send me a message or an invite and I'll record a quick Loom on how I'd approach your build. Excited to talk! ——— A little more about me: Pleasure to meet you! I'm Stratos. Most of my clients choose to work with me because of the way I think a problem all the way through, my fast replies, and the fact that I stand behind everything I ship. I previously spent a few years in IT and network infrastructure, running MikroTik routing and Windows Server environments, before going all-in on AI and automation. Once I saw how much repetitive work it could quietly take off a team's plate, there was no going back; things went well enough that I hit Top Rated with 100% Job Success inside my first year. Over the last couple of years, I've had the good fortune to work with (and gain knowledge of) a number of interesting, profitable industries. Among them: -performance-marketing & PPC agencies, -insurance & insurtech firms, -professional operations & support teams, -home-service & e-commerce companies, -healthcare & content businesses, and -SaaS & AI companies When you work with me on Upwork, you receive automations that run in production without babysitting and hold up when real users hit them. Every workflow has a purpose, every step earns its place, and every build is documented so nothing stays a black box. I build because I genuinely enjoy the process, the reasoning path to a solution is the part that pulls me in, and it lets me exercise my mind in a way that (frankly) most other things do not. I also provide exceptional value to my clients at fair rates, and my aim is always long-term, sustainable partnerships that allow both of us to thrive. Sincerely looking forward to building something great for you. Let me know if you have any questions or want further information and we'll connect. Cheers, Stratos P.S - if you work with a tool, platform, or industry that I didn't directly list, I would still encourage you to reach out. I enjoy immersing myself in new problems and improving my knowledge; more than willing to be flexible, given that it's an investment that makes sense for the both of us. ——— ✅ Why clients keep me on speed dial: → 55+ projects shipped across automation and AI builds → 100% Job Success Score | 5.0★ rating → Daily tools: n8n, Airtable, Zapier, Make, Python where it's needed → Most clients see ROI in the first month or two → I reply fast, write messages myself, and don't disappear mid-project 🧰 EXPERTISE: → AI Agents: AI Automation | AI Agent Development | ChatGPT | Claude | LLM Implementation | AI Chatbots → Automation Platforms: n8n | Zapier | Make | Airtable | No-Code Development → Custom Builds: Python | TypeScript | REST API | API Integration | Database Design → Business Ops: Workflow Automation | Business Process Automation | Digital Workers
