I build Python backend systems that hold up as they grow — designed properly from the start, so you're not rebuilding them a year later when traffic or features outpace the original setup. Most backend problems aren't really about writing code. They come from decisions made early that get expensive later. I focus on getting those right: how the system is structured, how the data is modeled, where the bottlenecks will show up, and what to build now versus what to leave room for. That judgment is what separates a system that scales from one that gets rewritten. What I do: Backend & APIs — FastAPI and Django REST, built for real traffic. Versioned, well-structured APIs with proper error handling, pagination, and idempotency — not just happy-path code. Architecture & scale — Multi-tenant SaaS systems with tenant isolation and role-based access. Structuring services and data flow so the system stays maintainable as it grows, not just on day one. Data layer — PostgreSQL schema design, indexing, query optimization, and migrations without downtime. Redis for caching and queues. Async & background work — Celery, event-driven workflows, webhook handling, and retries — the parts that need to keep working when external services don't. Taking it to production — I deploy what I build: Docker, AWS/GCP, CI/CD, and monitoring. I own the system end to end, so nothing gets handed over half-finished. When a system needs it, I also cover automation — n8n, Make, Zapier, or custom Python scripts — along with payment and third-party API integrations, so you get a complete build rather than parts to stitch together. Why hire me: 70+ completed projects, $80K+ earned on Upwork, 5,500+ hours, and consistent 5-star reviews. Recent work includes a recruitment platform handling 50K+ requests/day, a multi-service exam platform, and multi-tenant SaaS systems running in production. The code is clean, documented, and maintainable, and I deliver on time. If you need a senior engineer to build a backend that stays reliable long after launch — and to make the right calls while building it — message me. Tech: Python, FastAPI, Django, PostgreSQL, Redis, Celery, Docker, AWS, GCP

𝗙𝘂𝗹𝗹-𝗦𝘁𝗮𝗰𝗸 𝗙𝗼𝘂𝗻𝗱𝗮𝘁𝗶𝗼𝗻𝘀 Every AI product needs scaffolding that holds. I've shipped Django/Node/React/Next.js platforms that ran 3+ years in production, Alchemist Real Estate, audIT.app, and a long-running B2B SaaS that grew from MVP to hundreds of users across $195K+ in contracted development. Distributed backends, REST/GraphQL APIs, AWS-native deployment, data pipelines, and the DevOps to keep them stable. 𝗛𝗼𝘄 𝗜 𝘄𝗼𝗿𝗸 As Lead Engineering Architect, I stay hands-on through the whole lifecycle, discovery, architecture, core implementation, deployment, and the long tail. I don't hand off and disappear. Most of my Upwork work is repeat business or long contracts measured in years, not weeks. If you're building a Voice AI agent, a computer vision platform, an LLM-driven workflow, or a full-stack AI product that needs to survive real load - let's talk.

I am an architect and builder of backend systems that handle millions of transactions, process data at scale, and stay resilient under pressure. Over 30 years of professional experience across telecoms, financial services, eCommerce, industrial automation, and high-performance computing have given me a deep understanding of what it takes to deliver systems that actually work in production — not just on paper. My career has been built on two pillars: technical depth and structured methodology. I write production code in Java (since 1996) and C++ (since 1984), and I architect the systems around it — from data models and API contracts to deployment strategies and fault tolerance. I'm equally comfortable designing a distributed architecture from scratch and diving into code to solve a performance bottleneck. Clients I've delivered for include Jet-com/Walmart, McLane, Accenture, Vodafone, Nokia-Siemens Networks, Amadeus, and several major Italian Banks. Beyond individual contributor work, I've led engineering teams in complex environments and critical projects. My approach to architecture is systematic and documentation-driven. Every engagement follows a structured process: requirements analysis, boundary condition mapping, data model definition, security strategy, component selection (with a strong preference for well-maintained open-source), API and protocol design, and deployment planning, including clustering, geo-distribution, redundancy, and fault tolerance. Security is not a layer I add at the end — it's embedded in how I think about every design decision. Zero-trust architectures, TLS/SSL, OAuth2/OIDC, RBAC, and CI/CD pipeline hardening are foundational elements, not afterthoughts. I deliver production systems that perform, scale, and hold up under real-world conditions. If your project needs an architect who also codes, leads teams, and takes ownership end-to-end — let's talk.
