Having extensive expertise in project management, finance & investments, accounting and business leadership, I position myself as a web developer with finance and business insight. I believe that code is for users not for developers, therefore I look at algorythms from the standpoint of the final beneficiary to make them smooth and easy to understand. I look for interesting and challenging projects, but will accept minor tasks, like cleaning your code from bugs and understanding the logic of your shopping engine. My specialities: 1) backend: - Python stack (Django, Flask, FastAPI), - PHP stack (Laravel, Zend Framework), - Node.JS stack (AWS Lambdas, Express.js, Next.js) 2) databases and data stores: MySQL, PostrgreSQL, MSSQL, MongoDB, Redis 4) frontend: plain Javascript, ReactJS, Angular, Vue.JS, 5) mobile: React Native, 6) integration between web and corporate systems (ERP and Accounting systems, Warehouse management systems, call management systems); 7) devops: full scope Linux Server administration; cloud administration for AWS, Google Cloud, IBM Cloud, Openshift; CI/CD with initiation from github / bitbucket; docker / k8s, auxiliary technologies.

I’m a pragmatic full-stack developer with 5+ years of experience specializing in Python (Django, Flask), React, and production REST APIs. I ship reliable, scalable web apps and backend systems with clean PostgreSQL designs and repeatable deployment processes. I’ve led releases, implemented CI/CD workflows, and designed optimized PostgreSQL schemas for high-read systems. Recent contract work involved debugging large Django codebases, building APIs for dashboards, and delivering frontends for Elixir/Phoenix projects. I prioritize clean architecture, automated tests, and clear communication so you get reliable code and predictable delivery. My approach is API-first, testable, and focused on user experiences and robust functionality. My Full Tech Stack (high level) Frontend: React (hooks, component libraries), JavaScript (ES6+), HTML5, CSS3, Tailwind CSS, Bootstrap, SASS, responsive design.

Python AI developer and full-stack engineer with 6 years shipping production SaaS platforms, AI-powered systems, and complete MVP builds across healthcare, legal, retail, e-commerce, and construction tech. I work across FastAPI, React, TypeScript, Supabase, PostgreSQL, Stripe, OpenAI, LangChain, and AWS. I own the full product from database schema to deployed frontend. If you are building something that needs AI built in from day one, not bolted on later, that is what I do. I have shipped RAG pipelines with hybrid vector and keyword retrieval, multi-LLM orchestration layers abstracting 7 providers behind a single interface, LangChain agents with custom tool chains, and GPT-powered automation engines that replace entire human workflows. The AI is not a feature. It is the architecture. Here is what I have built as sole architect and developer. An AI scheduling SaaS currently live with paying customers. FastAPI backend on Supabase with full Stripe billing, React frontend with interactive Gantt visualization, and an Azure OpenAI pipeline that converts raw project scope documents into fully dependency-mapped schedules. What used to take a planning team 2 to 3 weeks happens in minutes. Multi-tenant RBAC, JWKS JWT auth, deployed on Render. An enterprise eDiscovery platform that is SOC 2 certified and runs across AWS, Azure, and GCP. FastAPI, PostgreSQL, Redis, Celery, Apache Solr, and Qdrant with hybrid RAG retrieval. Seven LLM providers unified behind one interface. Fifty domain modules. This is the type of system law firms pay $500K per year to access from commercial vendors. I built it from scratch. A full hospital operations SaaS for pediatric clinics. FastAPI, PostgreSQL, Redis, React TypeScript. The encounter engine creates 7 entity types inside a single ACID transaction. Invoice sequencing uses pessimistic row locking so numbers are always sequential under concurrent billing load. Five role tiers across 60 protected routes. A workflow that used to take 15 minutes at the front desk now takes under 30 seconds. A fully serverless retail collaboration platform on AWS. Twenty plus Lambda functions with 3 shared internal Python packages distributed via CodeArtifact. A LangChain AI agent with 6 integrated tools embedded inside a real-time chat interface. Notification fan-out across 6 channels from a single pipeline. Differential CI/CD across 4 environments so only the functions that changed get redeployed. An AI sales automation engine that replaced a 2 person SDR team. The system pulls real Gmail conversation history, injects it into GPT prompts, generates context-aware follow-up emails, and threads them back into the original conversation via RFC822 headers. Reply detection resets the sequence automatically. Over 1000 Pipedrive deals processed every minute during business hours with no human in the loop. A full-stack e-commerce operations platform that collapsed 6 separate tools into one system and cut daily operational overhead from 3 hours to 30 minutes. Multi-source order ingestion, automated SMS lifecycle, dual Kanban CRM with cross-entity SQL deduplication running every 5 minutes, one-click USPS batch processing. For clients I build full-stack SaaS MVPs with FastAPI or Node backend, React or Next.js frontend, Supabase or PostgreSQL, Stripe billing, and CI/CD deployment. Complete products with no handoffs. I build AI and LLM integrations that go beyond calling an API. RAG pipelines, LangChain agents with custom tools, OpenAI and Azure OpenAI, vector search with Qdrant or FAISS, document processing pipelines, GPT-powered workflows that eliminate manual processes. I build Python backends with multi-tenant RBAC, Celery task queues, Redis, WebSocket delivery, SAML SSO, and JWT auth. Production concerns are the default, not an upgrade. I also have genuine domain experience in healthcare software, construction and project management tooling, legal tech, and e-commerce operations. These are not projects I read about. They are systems I designed and shipped. Every system I deliver has proper auth, error handling, structured logging, and a working deployment pipeline. I do not build prototypes. I build things that run in production without anyone watching them. Available for full-stack development, AI integration work, SaaS MVP builds, and long-term product engineering engagements.

Has growth started exposing cracks in your product ❓ 🔴The real challenges usually appear later: slow APIs, technical debt, rising cloud costs, and systems that become harder to scale as the product grows. Launching a product is one milestone. Keeping it fast, reliable, and easy to improve six months or two years later is a completely different challenge. 🔰That's where good software engineering starts to matter. Over the last 𝟭𝟬+ 𝘆𝗲𝗮𝗿𝘀 and 𝟯𝟬+ 𝘀𝘂𝗰𝗰𝗲𝘀𝘀𝗳𝘂𝗹 𝗽𝗿𝗼𝗷𝗲𝗰𝘁𝘀, I've worked on SaaS products, startup MVPs, and AI-powered applications where the ability to scale directly affected how fast teams could ship, iterate, and grow. 🔹Growth Challenges: As products grow, keeping development fast and predictable becomes increasingly difficult. APIs struggle under increasing load, technical debt starts affecting delivery speed, infrastructure costs rise, and systems become harder to maintain and scale. Without the right technical foundation, these issues can gradually impact product velocity, reliability, and user experience. 🔹What I Help With: ▸ Scale Your SaaS Build and improve SaaS platforms that remain reliable, maintainable, and ready for growth as users and features increase. ▸ Speed Up Your APIs Identify bottlenecks, improve response times, and build backend systems that perform reliably under load. ▸ Cut Your Cloud Bills Optimize cloud infrastructure, eliminate unnecessary costs, and improve efficiency without compromising reliability. ▸ Automate with AI Implement AI-powered features, workflow automation, and intelligent tools that improve productivity and user experience. ▸ Launch MVPs That Scale Build startup MVPs with a solid technical foundation that supports future growth without major rewrites. 🔹Tech Stack: Frontend: React, Next.js, TypeScript, Angular Backend: Node.js, NestJS, Express.js, Python Database & Cloud: PostgreSQL, MongoDB, MySQL, DynamoDB, Supabase, AWS, Google Cloud Integrations: REST APIs, Stripe, PayPal, Apple Pay, Twilio DevOps & Tools: GitLab CI/CD, Jenkins, Git, Automated Testing, Deployment Automation 🔹WHY WORK WITH ME ▸ Systems built for scale, performance, and long-term stability ▸ Engineering decisions driven by real product impact ▸ Direct collaboration with the developer building your system ▸ Experience across SaaS, MVPs, backend systems, and AI applications ▸ Focus on clean architecture and production-ready delivery Ready to Scale Without Breaking?
