🔥I help startups and growing businesses build fast, scalable web and mobile apps using Python, Laravel, React Native, and React. I work as a full stack developer who can take a product from idea to production with clean code and predictable delivery. If you need a reliable web developer for modern UI work and a strong mobile app developer for iOS/Android builds, I can cover both while staying hands-on as a full stack developer focused on performance, UX, and maintainability. I’ve delivered solutions for founders who need speed now and stability later, and I communicate clearly at every step.🔥 🚀I also lead a web development team, Join.To.IT from Kyiv, Ukraine as co-founder and CEO. We have multiple Laravel developers (Senior PHP and Custom PHP MySQL), Python (Django), and JavaScript (React, Vue, React Native) developers. If your project needs a dedicated mobile app developer, we can staff that role quickly, while I stay involved as a full stack developer to keep architecture, delivery, and communication aligned. When the UI scope grows, a senior web developer can join the project while I remain the full stack developer responsible for end-to-end quality.🚀 I’m an experienced Laravel engineer, React engineer, Vue engineer, and React Native engineer with 14 years of production experience. As a full stack developer I can build backend APIs, admin panels, dashboards, and customer-facing apps, and as a web developer I pay attention to UI details that improve conversion and retention. I’ve completed a wide range of successful projects, from MVPs to large systems with long-term maintenance and continuous improvements. My skills: React React Native Software Architecture & Design Laravel Python Full-Stack Development API Development JavaScript PHP Web Application Development Node.js AWS Development MySQL Mobile App Development Django WordPress HTML5 Tailwind CSS Web Design API Integration Stack of technologies we use: ✅ HTML/CSS, Bootstrap, Tailwind ✅ JavaScript (React, Vue, Node.js, Express, AdonisJS, Nuxt) ✅ React Native for cross-platform mobile delivery ✅ API integrations (Stripe, PayPal, Twilio, TextMagic, Xero, DocuSign, Google Maps, Meta APIs, and more) ✅ API development (Laravel, Node/Express, Firebase, Python/Django, Go, REST, GraphQL) ✅ PWA (Progressive Web App) ✅ Databases: MySQL, PostgreSQL, MongoDB, DynamoDB, Elasticsearch ✅ Infrastructure: AWS, DigitalOcean, Firebase, Supabase ✅ DevOps and administration: LAMP, CentOS, Ubuntu As a full stack developer, I connect the front end, back end, and infrastructure so releases are smooth. When the scope includes native-like UX, I can collaborate with a mobile app developer without slowing down the API roadmap, and a web developer can refine UI flows while we keep the backend stable. You can hire me as a full stack developer for full ownership, or extend the team and keep me as the full stack developer leading architecture and delivery. If timelines are tight, add a mobile app developer to parallelize mobile features, and add a web developer to accelerate dashboards and front-end work. Our team has already worked in such industries as: ✅ Marketplace ✅ E-commerce ✅ Travel and Hospitality ✅ Custom ERP (Enterprise Resource Planning) ✅ ChatGPT integration (LLM model in your website front end) ✅ Automotive (car inspection, automotive ERP, car sharing, rental, selling) ✅ Social media (Tinder-like networks, short video platforms, communities) ✅ Sales (CRM systems for sales teams, retail, hospitals, sales departments) ✅ Sport (gym management systems, trainer platforms, fitness apps, club portals) ✅ Legal (document automation, AI-assisted legal processing) ✅ Healthcare (clinic management, booking, mental health software) ✅ Education (LMS, automated training, coaching marketplaces) ✅ Finance (fintech platforms, investment platforms, bank API integrations, calculators) ✅ Manufacturing (shop floor management and automation) ✅ Human resources (HRM systems) ✅ Digital marketing (Meta, Facebook/Instagram, TikTok, Google APIs, analytics) In our work history you’ll find successful products built with Laravel, PHP, JavaScript, MySQL, React, Vue, WordPress development, Web Development, Full Stack development and React Native, plus multiple systems built with Python (Django, Flask, FastAPI). I also use LLM capabilities and AI APIs (including OpenAI integrations) when they genuinely improve the product experience. We have 65 senior developers across PHP, JavaScript, MySQL, Python, Go, and Node.js. As a full stack developer, I can jump into an existing codebase, stabilize releases, fix bottlenecks, and plan the next iterations. Don't hesitate to get in touch with me for further details and fruitful work. Best regards, Oleksandr CEO, JoinToIT

Senior Data Engineer and AI Engineer with 15+ years in data engineering, AI engineering, and cloud data platforms. I build production data pipelines, ETL workflows, LLM and RAG systems, and machine learning infrastructure on AWS, GCP, Azure, Snowflake, Databricks, and Apache Spark. Most of my data engineering work is end to end. I take a messy data problem, or an AI feature that "almost works," and turn it into something reliable that runs in production without someone babysitting it. After 15+ years as a data engineer, you learn the hard part is rarely the model or the framework. It's the data, the edge cases, the pipelines, and keeping the system maintainable once you've handed it over. As an AI engineer I treat LLM and RAG work the same way: take a prototype that almost holds together and make it a production AI system that survives real traffic, real users, and real data. Recent data engineering and AI engineering projects: - An AI inbound phone system built on Twilio with OpenAI Whisper and GPT-4, handling real-time voice intake and call routing. - Enterprise Power BI data models for healthcare and financial reporting, around 30 tables and 40+ DAX measures, including IFRS 9 staging, RAROC, and NIM trends. - HL7 FHIR R4 integrations with Epic, Cerner, and Athenahealth for a clinical AI platform. - Cut LLM inference cost on a high-volume voice product by 25% by reworking how it used the OpenAI Realtime API and its per-turn token replay. Data engineering: Apache Spark, PySpark, dbt, Apache Airflow, ETL and ELT pipelines, data warehousing, data modeling, Snowflake, BigQuery, Redshift, Databricks, Delta Lake, Kafka, Kinesis, Fivetran. AI engineering and machine learning: OpenAI GPT-4o, Claude, Gemini, LangChain, LlamaIndex, RAG pipelines, AI agents, prompt engineering, vector search (Pinecone, Weaviate, pgvector), PyTorch, TensorFlow, scikit-learn, MLflow, model deployment. Cloud and DevOps: AWS (Glue, EMR, Lambda, Redshift, SageMaker, Athena), GCP (BigQuery, Dataflow, Vertex AI), Azure (Synapse, Data Factory, Azure ML), Terraform, Docker, Kubernetes, GitHub Actions. Automation and integration: n8n, Make, Power Automate, REST and GraphQL APIs. Governance and compliance: GDPR, HIPAA, SOC 2, RBAC, PII masking, encryption, data lineage. Languages: Python, SQL, Scala, PySpark, FastAPI, Flask. How I work: I'd rather ask the right questions up front than build the wrong thing quickly. I'll tell you when something is a bad idea, give you timelines I can keep, and leave you with code and documentation your own team can maintain. I've delivered data engineering and AI engineering projects for startups and enterprises across the US, Europe, and Asia. If you're looking to hire a data engineer or AI engineer who can own the work end to end, from raw data pipeline to production AI system, I'm available now. Tell me what you're building and I'll give you a straight answer on how I'd approach it.

Hi there! 👋 As a dedicated Full Stack Developer and SaaS Developer, I focus on engineering Custom Business Applications and production-ready software that holds up under real-world usage. My commitment to quality and client satisfaction is reflected in my 100% Job Success score on Upwork. My work sits at the intersection of software developer, web developer, and SaaS platform builder, with a deep attention to scalability, performance, and long-term maintainability. As a Full Stack Developer, I take ownership of systems end-to-end, pairing robust backend architecture with clean, modern interfaces. My frontend work is typically React-based, and I often collaborate with or replace traditional React developer or web developer setups by owning both frontend and backend in a single, coherent system. In the past few years, I’ve integrated an AI-first mindset into my workflow, using Python to build intelligent automations and LLM-driven features. As a SaaS Developer, I help companies design, build, and scale SaaS products, internal tools, and API-driven web applications intended for long-term use. My experience as both a software developer and SaaS development expert allows me to think beyond features and focus on architecture, reliability, and operational stability from day one. Many of the platforms I build include Healthcare applications, CRM, ERP, and custom portals where permissions, data integrity, and business rules are critical. In my day-to-day work, I design and implement backend services, APIs, and data models that power SaaS and complex web applications. I regularly work with Node.js, PHP (Laravel), and Python, drawing on my background as a Python developer to build scalable services, background jobs, and asynchronous workflows that perform reliably in production. As a Full Stack Developer and CTO, I ensure these backend systems integrate cleanly with frontend applications and third-party APIs. When required, I support react developer and mobile app developer workflows to deliver seamless user experiences. This end-to-end ownership is a key reason clients bring me in as a Full Stack Developer rather than splitting work across multiple roles. A significant portion of my work involves building internal platforms and API-first systems. In these projects, I often collaborate with teams focused on saas marketing by designing clean data pipelines and backend logic. My versatility as a wordpress developer and web developer allows me to bridge the gap between marketing sites and complex backend systems, including integrations with legacy CMS or WordPress-based systems when required. Clients typically work with me when they need: a Full Stack Developer laravel who can own frontend and backend a SaaS Developer who understands long-term scalability constraints a Backend Developer experienced with Node.js, PHP, and Python mobile app developer and react developer experience as a software developer backend services built with Node.js or Python by an experienced Python developer web applications with complex workflows from a senior web developer a wordpress developer for custom theme/plugin logic and API integrations SaaS platforms designed to support growth and saas marketing data needs MVPs that can realistically evolve into long-term SaaS products A large part of my work as a Full Stack Developer, SaaS Developer, and Backend Developer focuses on: -multi-role dashboards and internal tools (CRM & ERP) -authentication, authorization, and permissions -API-first backend system design -integrations with external platforms, including WordPress systems -Secure cloud solutions using AWS My core work as a Backend Developer and Full Stack Developer, CTO covers: backend services built with Node.js, PHP, and Python APIs, background jobs, and integrations databases such as PostgreSQL and MySQL modern stacks using tools like React, Vue.js, and Laravel AI-enabled backend features where they add real business value I regularly work on MVP builds as a SaaS Developer, with a focus on solid backend foundations and avoiding short-lived prototypes. Based on scope and timing, I work hands-on as a Full Stack Developer, SaaS Developer, and Backend Developer. Long-term results come from clarity and intentional system design. I focus on delivering software that teams can confidently run, maintain, and scale.
