✔️ Top-Rated Full Stack Developer on Upwork - $350K+ earned, 100% Job Success Score ✔️ 25,000+ hours delivered across long-term contracts since 2014 ✔️ 15+ years freelancing, mostly on Upwork - based in Bulgaria ✔️ Multiple 5+ year client relationships, because clients keep me when the work delivers ✔️ University graduate in IT and Automation 🚀 What I Do I'm a Senior Full Stack Developer who builds AI-powered web applications and connects systems that need to talk to each other. Most of my work falls into one of three buckets: building new platforms from scratch, integrating AI into products that already exist, or stepping in as a long-term technical partner for teams that need someone reliable. I'm not a "yes man." If I see a better way to do something, I'll tell you. If I see risks in your current approach, I'll tell you that too. Some clients love this, some don't. If you want someone to just nod and code, I'm probably not your best fit. 🤖 AI Integration & Automation - AI API Integration with OpenAI, Anthropic, and Google AI - Chatbots, document processing, and content generation pipelines - Automation workflows using n8n, MCP, and custom tooling - Adding AI features to existing platforms without breaking them 🛠️ Full Stack Development - Backend & APIs: Go, PHP/Laravel, Python/FastAPI, Node.js, REST, GraphQL - Frontend: React, Next.js, JavaScript, TypeScript, HTMX - Integrations: Shopify API, Apache Kafka, RabbitMQ - Data: MySQL, PostgreSQL, ELK - Infrastructure: Docker, Kubernetes, Linux, Prometheus, Grafana 💼 Recent Work I'm Proud Of - Open Banking infrastructure: 2 years on the backend team building UK Open Banking standard infrastructure. Conducted API conformity tests for a major US bank that played a crucial role in their CMA approval to operate in the UK market. - Logistics platform optimization: Replaced a complex Zapier-based workflow with a standalone server. Cut operational headcount from 10 managers to 1, saves a few thousand USD per month, and dramatically reduced human error. The producers, packagers, warehouse, drivers, operators, and owner are all happy with the new system. - Custom Go authentication systems, Grafana dashboards for fintech monitoring, and a number of long-term technical specialist roles where clients kept me on for 5+ years. 💬 What Clients Say "A fantastic developer, total integrity and very reliable." - Golang full stack client (1,500+ hours) "One of the best guys we worked with." - Long-term hosting and infrastructure client "This professional is very capable. He showed proper commitment and deserves special recognition for his seriousness and correctness." - Recurring enterprise client 🎯 How I Work: The 3Cs - Confidentiality: I treat your data and business with the same care as my own - Continuous Improvement: I stay curious, current, and always learning what matters - Commitment: I approach every project as if it were my own business 📩 Let's Talk If you need a senior developer who's honest about what works and what doesn't, owns the outcome, and stays for the long term, I'd be glad to chat. I usually respond within a few hours during business days.

As a Full Stack Software Developer with over 2 years of experience, I specialize in creating high-performance applications utilizing Golang and React. I am passionate about building scalable, efficient, and user-friendly web applications that deliver real value to clients. Languages: Golang, Typescript, Python Frameworks: Django, Flask, Go-Chi, Gin Gonic, ReactJS, ExpressJS Databases: PostgreSQL, Microsoft SQL Server, MongoDB, Redis Technologies: Kafka, Consul, OCP, Prometheus, Grafana, Jaeger I am committed to delivering projects on time and within budget, while maintaining open and transparent communication with clients throughout the process. Let’s connect and turn your ideas into reality!

I'm a full-stack engineer with 19+ years of delivery experience, and I use AI-agentic workflows to help startups and businesses ship production-grade products faster without the quality trade-offs that usually come with "fast." My stack is PHP/Laravel, Python, Go, Vue/Nuxt, and modern cloud (AWS). But the real difference isn't the tools it's how I use them. Every project starts with Spec-Driven Development: I turn a vague idea into a precise, reviewable spec before a line of code is written. AI agents (Cursor, GitHub Spec Kit) then handle the implementation heavy-lifting, while I provide the senior oversight that keeps the output clean, scalable, and free of the hallucinations and technical debt that sink most "AI-built" projects. When a fast prototype is what you actually need, I'll reach for rapid AI prototyping too but always with a clear path to production. WHAT THIS MEANS FOR YOU - Faster launches spec-first planning plus AI execution compresses delivery time substantially. - Quality that holds up every spec and every commit is reviewed by a senior engineer, never shipped blind. No "vibe coding" chaos. - Fewer rewrites getting the spec right upfront means we build the right thing once. - Predictable scope & cost you see and approve the plan before work begins, so there are no surprises. FULL-STACK OWNERSHIP, END TO END - Backend: Laravel, Go, Python APIs, queues (RabbitMQ/Redis), high-traffic systems. - Frontend: Vue/Nuxt, responsive and accessible UIs. - Databases: MySQL, PostgreSQL. - Cloud: AWS (Lambda, S3, RDS, ElastiCache). - AI integrations: Claude, GPT, Copilot automation, predictive insights, personalization. I handle zero-to-one MVPs, legacy modernizations, and AI-enhanced features across finance, healthcare, e-commerce, and more. HOW I WORK WITH YOU - Flexible availability across US, Australia, and EU time zones. - Transparent communication, collaborative iteration, and strategic guidance — not just code. - A track record of high-traffic apps maintained at scale, revenue-driving features shipped on time and budget, and long-term partnerships built on trust. If you're looking for a senior partner who can move fast and deliver code that lasts, let's talk. Message me to discuss your project I'm ready to help you launch faster, smarter, and stronger.

Sole technical owner on everything I've shipped, for 8+ years. The biggest: 3+ years as sole technical founder at Due Diligence Software, an Australian legal-tech startup, where I built and scaled an enterprise SaaS for AI-powered due diligence to 750+ users and 50K+ documents. Architecture, AWS infrastructure, billing, auth, integrations, the 3am incidents: every technical decision was mine. After that I built LegalSort solo: an AI legal-document classifier on multi-agent LLM pipelines (Claude, RAG, structured outputs), deployed on AWS. Not a GPT wrapper: custom sampling engine, document taxonomy, schema-validated outputs, confidence scoring, human in the loop. What I offer: 1. AI/LLM engineering. Production LLM systems: multi-agent architectures, RAG pipelines, Claude and OpenAI integrations, evals, prompt engineering at scale. Shipped in my own products and built for clients. 2. Vibe-code cleanup and pre-launch review. Someone (or some tool) shipped you a codebase that "works" but isn't production-ready. I audit what's there, name what's structurally missing, and rebuild what has to survive real users. 3. Full-stack AI product development. End-to-end builds: Go or Node backend, AWS (Bedrock, Lambda, ECS, S3, SQS, SES), PostgreSQL, async pipelines, with the AI layer integrated properly, not bolted on. 4. Cross-platform mobile (React Native / Capacitor). Hybrid apps where the web stack carries over, including finish-and-ship work: taking an existing app the last mile to the App Store or Play Store. 5. Fractional CTO / technical advisor. Architecture reviews, technical roadmap, code review, due diligence on existing systems. Strongest fit for early-stage AI products. Clients keep me around: 100% of my client relationships have run longer than 90 days, several for 3 to 4 years. Top Rated, 100% Job Success, 4.9/5 overall rating across 40+ jobs. Good fit if you want someone who can actually ship AI products, and who'll tell you when something is the wrong call. I give honest pushback, not cheerful agreement.

I build mobile apps that people actually want to use. Over the years, I’ve worked with startups, established businesses, and growing teams to turn ideas into solid mobile products. I’ve handled everything from early MVPs to big, complex apps, always focusing on performance, making things scale, and keeping the user experience smooth and intuitive. I don’t lock myself into just one technology. I pick what fits each project best and take responsibility from start to finish planning, building the architecture, coding, testing, launching, and then improving things as the product grows. My skills go beyond just mobile. I know my way around backend tools like Node.js, Golang, MongoDB, and SQL, so I see the bigger picture. This helps me work closely with teams, tackle tough problems, and build apps that can grow alongside your business. I care about direct communication, thoughtful engineering, and building partnerships that really last. For every project, my goal stays the same: make something that’s genuinely valuable for both the business and the people using it.
