Building an AI demo is easy. Turning it into a reliable system that works with real data, business rules and existing tools is the difficult part โ€” and that is where I focus. I help businesses automate manual workflows, connect disconnected systems and build production-ready AI products. As an AI Developer and Full-Stack Engineer, I can take a project from process mapping and architecture to implementation, deployment and technical handover. ๐Ÿ“ฉ Send me your current workflow, technical challenge or product idea. I will help define a practical first milestone โ€” even if you do not have a finished specification yet. ๐Ÿ† WHY WORK WITH ME? โœ… End-to-end ownership: discovery, architecture, development, integrations, deployment and documentation. โœ… Controlled AI systems: approved knowledge sources, explicit boundaries, auditability and human escalation. โœ… Business-first automation: I start with the workflow and expected outcome, not with a fashionable tool. โœ… Production-ready engineering: validation, error handling, access controls, tests, CI/CD and monitoring considerations. โœ… Clear delivery: written scope, visible progress and maintainable code your team can continue operating. ๐Ÿค– AI AGENTS, RAG & KNOWLEDGE ASSISTANTS I build AI assistants that work with your companyโ€™s approved documents, product information and internal knowledge. This includes: โ€ข RAG pipelines and searchable knowledge basesโ€ข AI support and product assistantsโ€ข Source-grounded responsesโ€ข Conversation flows and clarification logicโ€ข Guardrails for sensitive or unsupported requestsโ€ข Human handoff with conversation contextโ€ข Knowledge versioning and review workflowsโ€ข Integration with websites, internal systems and messaging platforms One recent project involved an AI consultant for a vitamin catalogue. The assistant retrieves information from controlled product materials, explains products within approved boundaries and transfers medical or uncertain questions to a human specialist. The goal is not to make AI sound confident. The goal is to make its behaviour useful, inspectable and safe for the real business process. โš™๏ธ BUSINESS AUTOMATION & API INTEGRATIONS I design controlled workflows that connect websites, advertising channels, email, messengers, internal tools and CRM systems. A typical lead automation flow can include: โ€ข Lead capture and source attributionโ€ข Input validation and duplicate detectionโ€ข AI-assisted summaries and classificationโ€ข CRM routing and ownership assignmentโ€ข Telegram, email or internal notificationsโ€ข Follow-up tracking and escalationโ€ข Error logs, retries and operational visibility Instead of adding another disconnected tool, I build one transparent route from the incoming request to the responsible person and the next action. ๐Ÿง  DATA, MARKET & DECISION-SUPPORT SYSTEMS I also develop systems that collect external data, normalize it and evaluate scenarios through explicit rules. For an anonymized prediction-market project, I worked on a pipeline that: โ€ข collected and normalized market and external data;โ€ข compared market signals with scenario estimates;โ€ข applied validation, risk limits and stop conditions;โ€ข recorded accepted and rejected scenarios for later review. These systems are designed around traceability and controlled execution. I do not promise guaranteed trading or financial outcomes. ๐Ÿ’ป FULL-STACK WEB DEVELOPMENT I build internal tools, customer portals, SaaS products, dashboards and custom web applications. My typical stack includes: โ€ข TypeScript and Node.jsโ€ข React and Astroโ€ข NestJS and REST APIsโ€ข PostgreSQL and structured data validationโ€ข Dockerโ€ข GitHub Actions and CI/CDโ€ข Vercel and production deploymentโ€ข Third-party APIs, CRM and messaging integrations I select the architecture around the workflow, expected load and operating constraints instead of forcing every project into the same stack. ๐Ÿš€ DEVOPS, CI/CD & DELIVERY WORKFLOWS Reliable delivery is part of the product. For an anonymized marketing operations project, I helped create a shared delivery structure across multiple departments, including reusable CI/CD workflows, environment separation, access rules, release checks and documented recovery procedures. The result was a repeatable release process with clearer ownership, shared technical context and less dependence on informal knowledge. ๐Ÿ› ๏ธ WHAT I CAN BUILD FOR YOU โ€ข Custom AI agents and RAG assistantsโ€ข AI customer support and product consultantsโ€ข Business process and lead workflow automationโ€ข CRM, API and messenger integrationsโ€ข Internal tools and administration panelsโ€ข Customer portals and custom SaaS productsโ€ข Data collection and decision-support pipelinesโ€ข Telegram bots and notification systemsโ€ข CI/CD pipelines and deployment workflowsโ€ข MVPs and production-ready web applications

I'm a Full Stack Developer with 8+ years of experience helping startups and scaling businesses ship production-ready web and mobile products. I've delivered 10+ projects on Upwork, logged 1,000+ hours. I specialise in Laravel, Flutter, and React Native, and back every engagement with a 100% refund guarantee if I set the wrong expectation and can't deliver. I design and develop scalable digital products across web and mobile, everything from SaaS platforms and marketplaces to fintech apps and AI-powered systems. Whether you need a robust Laravel backend, a cross-platform Flutter app, or a React Native mobile solution, I architect solutions with performance, security, and long-term maintainability in mind. Clients come to me when they want clean code and reliable delivery, not just a freelancer who disappears after go-live. I've worked with US-based clients across industries, including Real Estate, Solar Energy, and SaaS. For MyClientWave, an all-in-one CRM for marketing agencies based in New York, I built a DocuSign-like e-signature system entirely from scratch, eliminating their dependency on third-party tools and saving high recurring costs. I also engineered a solar design feature that uses LiDAR data to generate 3D models of a client's house, calculate the optimal sunlight path across the roof, and recommend the best panel placement, a genuinely complex geospatial and data-engineering challenge delivered end-to-end. For HouseJet, a US real estate platform with 25,000+ happy homeowners and 1,200+ expert agents, I built core features of a property search and listing platform connecting buyers, sellers, and local agents across the United States. If you're looking for a developer who can take on technically demanding, product-critical features and deliver them reliably, that's exactly what I do. Unlike most developers who just execute tickets, I treat your product like my own. I ask the right questions upfront, flag architectural risks before they become expensive problems, and communicate proactively throughout the project. My long-term client retention rate on Upwork reflects that approach most clients return for their next build. โœ… I have experience building: - SaaS Platforms (Laravel + React/Next.js) - Mobile Apps (Flutter & React Native โ€” iOS & Android) - Marketplace & E-Commerce Platforms - CRM / ERP Systems - AI Agents, Chatbots & RAG Systems - Fintech & Payment Gateway Integrations - REST APIs & Third-Party Integrations - Custom E-Signature & Document Workflow Systems - Geospatial & LiDAR-Based Data Features - Real Estate Platforms & Property Search Engines โœ… My core tech stack: - Backend: Laravel, Node.js, Nest.js - Frontend: React.js, Next.js, Vue.js - Mobile: Flutter, React Native - AI/ML: OpenAI, LangChain, RAG Pipelines - Databases: MySQL, PostgreSQL, Firebase, Supabase - DevOps: Docker, CI/CD, AWS, DigitalOcean Thanks for taking the time to read this. I have a 100% success score on Upwork, it's because I get it right the first time, or I'll work for free until you're happy. If your project needs a developer who takes ownership, not just instructions, send me a message and let's talk.

Full Stack Developer (7+ yrs) specialized in AI automation and production SaaS. I help SaaS founders and ops teams replace slow, manual workflows with AI agents and full-stack software that runs at scale and that your team actually owns, not a demo you outgrow in a month. The gap I fill: most "AI developers" stop at an API call, and most automation freelancers can't ship production code. I do both, which is what real AI automation takes. Across 20+ products in fintech, edtech, and healthtech (HIPAA, PCI-DSS), I've led engineering teams and shipped systems that hold up under real traffic. Top Rated on Upwork. On a recent AI-SaaS build, I caught a critical Supabase Row-Level-Security hole the team had missed, outside my scope, and showed them the fix. That instinct to audit, not just code, is what you're hiring. WHAT I BUILD - AI Automation & Agents, LangChain / LangGraph multi-agent and tool-calling workflows, RAG pipelines (pgvector, Pinecone), and n8n / Make orchestration with branching, error handling, and human-in-the-loop. Plus custom MCP servers so AI works securely with your tools and data. - Full-Stack SaaS: Multi-tenant Next.js / NestJS / Node.js / Python products with Stripe billing, auth, admin dashboards, and analytics. Built end to end. - AI-Powered Ops: CRM and workflow automation (HubSpot, Salesforce, GoHighLevel) for lead enrichment, follow-ups, and pipeline automation.

After that, proactive updates, clean modular code, and support that doesn't vanish at launch. You get one person who's both an AI-automation architect and a senior Full Stack Developer production code, LLM orchestration that holds together, and documentation thorough enough that your team is never stuck depending on me. Send me two or three sentences about the workflow or product costing you the most time. I usually reply within a few hours, and most projects start within 48.

OpenAI developer hiring guide

Adding OpenAI models to a product or workflow requires more than connecting an API. Hiring an OpenAI developer brings specialized expertise to design, integrate, test, and optimize AI features so they work reliably within your existing applications and business processes.

What does an OpenAI developer do?

An OpenAI developer builds applications and workflows using OpenAI models, APIs, and developer tools. They combine software development with AI integration skills to create features such as chatbots, intelligent search, content generation, document processing, and workflow automation.

Depending on the project, OpenAI developers may:

  • Select and configure OpenAI models based on quality, latency, cost, and application requirements
  • Design prompts, structured outputs, tool calls, and multistep AI workflows
  • Build chatbots, assistants, content pipelines, and other AI-powered features
  • Connect OpenAI models with databases, APIs, business applications, and existing software
  • Implement authentication, permissions, data-handling controls, and other security measures
  • Test and evaluate AI outputs for quality, reliability, latency, and expected behavior
  • Monitor API usage and optimize model selection, prompts, caching, and workflows to manage costs
  • Fine-tune or customize models when the use case and available OpenAI capabilities support it

How to hire an OpenAI developer on Upwork

Upwork connects businesses with AI professionals experienced in OpenAI models, application development, and back-end infrastructure. The platform has facilitated more than $25 billion in economic opportunity for talent around the world. Follow these four steps to find an OpenAI developer for your project.

Step 1: Post your project

A clear job post helps OpenAI developers understand your use case, technical environment, and expected deliverables.

  • Describe your AI use case, such as a chatbot, document workflow, intelligent search, content pipeline, or business automation
  • Specify the OpenAI APIs, SDKs, models, or capabilities involved if you already know what your project requires
  • List relevant requirements such as tool calling, structured outputs, retrieval, streaming, or third-party integrations
  • Describe your existing application stack, databases, APIs, cloud infrastructure, and deployment environment
  • Define deliverables, timeline, budget, and any requirements around security, data handling, or performance
  • Adapt this software developer job description to fit your OpenAI project

Use the Job Post Generator, powered by Umaโ„ข, Upwork's Mindful AI, to get started faster. Describe your needs in a few sentences and Uma will draft a customizable OpenAI developer job post. On Upwork, the average time from job post to first proposal is three hours.

Step 2: Review proposals

Focus on candidates who can demonstrate experience integrating AI into working applications rather than familiarity with OpenAI tools alone.

  • Examine portfolios for deployed chatbots, AI workflows, search experiences, automations, or other relevant applications
  • Confirm experience with the OpenAI API, SDKs, tool calling, structured outputs, and other capabilities your project requires
  • Look for evidence of thoughtful approaches to evaluation, latency, reliability, security, and API costs
  • Assess experience integrating models with databases, APIs, business applications, or existing software
  • Read client feedback for technical execution, communication, and reliable delivery

Uma can conduct instant video interviews and provide side-by-side candidate comparisons to help you narrow your shortlist.

Step 3: Conduct interviews

Use interviews to understand how candidates design, evaluate, and operate OpenAI-powered applications in production.

  • Ask candidates to walk through an OpenAI integration they've deployed and explain their technical decisions
  • Discuss how they choose models based on quality, latency, cost, and application requirements
  • Explore how they implement tool calling, structured outputs, retrieval, or other capabilities relevant to your project
  • Ask how they test AI outputs and handle inaccurate, unexpected, or failed responses
  • Discuss their approach to API security, data privacy, monitoring, version control, and deployment
  • Review these AI developer and machine learning engineer interview questions for additional prompts
  • Consider a small paid test project based on a contained integration or feature

Schedule and conduct interviews within Upwork Messages, where you'll receive a transcript and summary after each conversation.

Step 4: Hire and collaborate

Before development begins, align on deliverables, milestones, access, evaluation criteria, and ongoing responsibilities.

  • Define milestones such as prototype, API integration, evaluation, application integration, testing, and production deployment
  • Agree on success criteria for output quality, latency, reliability, cost, and other relevant measures
  • Provide appropriate access to repositories, development environments, APIs, data sources, and cloud infrastructure
  • Clarify responsibility for OpenAI accounts, API credentials, usage costs, deployment, monitoring, and ongoing maintenance
  • Establish requirements for handling confidential or sensitive data and protecting API keys and other credentials
  • Confirm ownership of source code, prompts, configurations, evaluations, documentation, and other project assets
  • Choose a fixed-price contract for defined deliverables or an hourly contract for evolving or ongoing development

Use Upwork's contract workroom and Messages to keep communication, files, and approvals organized. Identity verification, Hourly Payment Protection, hourly tracking, and project funds help keep the engagement secure, while Uma can help track milestones and next steps.
