I've saved companies over $120K every year on manual work and built multiple SaaS platforms from ground to a combined $110K ARR.

I build solid, reliable infrastructure with proper documentation. I've deployed 49 completed projects, writing the actual APIs, databases, and custom backend code behind the automation so the systems keep running when someone changes a field name at 2 AM. I'm a Microsoft Certified AI Engineer (AI-102) and an Upwork Top Rated Developer. You can't fake that status.

I help with full-stack AI product work at different stages: a single AI feature, a RAG pipeline, an AI agent, a Voice AI workflow, an MCP integration, a SaaS MVP, or a full production platform. Most AI projects do not fail because the model is bad. They fail because the scope is unclear, the workflow is messy, the data is not structured, the integrations are fragile, or the prototype never becomes a production system. โญ Top Rated Plus | Top 3% of performers on Upwork โ 10+ years building SaaS and AI products | 100+ projects delivered โ AI that ships: RAG, AI agents, MCP, Voice AI, LLM integration โ Full stack: Next.js, React, TypeScript, Python, Node.js, PostgreSQL, AWS โ SaaS, MVPs, automation, fintech, healthcare, construction, legal tech, and sales products You can hire me when: - You need one AI feature added to an existing app - You want OpenAI, Claude, Gemini, or MCP integrated into your product - You need a RAG system over PDFs, documents, knowledge bases, or internal data - You want a voice AI agent for calls, bookings, lead qualification, or CRM updates - You have a workflow involving documents, calls, follow-ups, data entry, or reporting that should be automated - Your MVP is half-built, buggy, slow, or stuck before launch - You need someone to build a full SaaS product from idea to deployment I work well on both small and large projects. If the right first step is a quick audit, prototype, bug fix, integration, or one-week milestone, I will tell you that. If the project needs a full build, I can own the architecture, frontend, backend, AI layer, deployment, and documentation. The part most AI freelancers skip: AI is rarely the whole product. It usually needs a backend, dashboard, auth, billing, permissions, logs, human review, and deployment around it. I build both the AI layer and the product around it. WHAT I DO: - AI SaaS & MVP builds: idea to deployed product with auth, billing, dashboards, and AI layer - AI inside existing products: RAG, agents, MCP, LLM features, document AI, and automation - Voice AI: agents that answer calls, book appointments, qualify leads, and log to your CRM - RAG and document AI: source-grounded answers, OCR, extraction, citations, and review queues - Workflow automation: documents, follow-ups, data entry, reporting, and API integrations - Rescue & ship: half-built MVPs refactored, hardened, and launched RECENT DELIVERIES: - AI sales CRM: call transcription, follow-up automation, multi-tenant pipelines - RAG document platform with every answer cited to source - AI financial intelligence platform: open banking + accounting sync into one ledger - AI voice agents for healthcare and sales, answering real calls daily - Turnkey B2B SaaS platform for the construction industry, end to end HOW I WORK: - I start by understanding the workflow, users, data, and business goal - I suggest the smallest useful first milestone when possible - I scope clearly before code is written, so you know cost and timeline up front - I can work on focused tasks, short prototypes, rescue work, or full product builds - I work full time on Upwork with overlap for US and European business hours If you need one AI feature, a quick prototype, a stuck MVP fixed, or a full SaaS product built, send me a short description of what you have and what you want it to do. I will reply with the clearest next step, the likely scope, and the first milestone I would recommend. Tech Stack: AI and LLM: OpenAI, Claude, Gemini, LangChain, LangGraph, CrewAI, MCP, function calling, model routing RAG and vector search: RAG pipelines, embeddings, semantic search, pgvector, Pinecone, document AI, OCR AI agents and automation: multi-agent systems, AI copilots, workflow automation, document extraction with review queues AI reliability: evaluation sets, hallucination reduction, human-in-the-loop workflows Voice AI: Vapi, Retell, ElevenLabs, Deepgram, OpenAI Realtime, Twilio Frontend: Next.js, React, TypeScript, Tailwind CSS, React Native Backend: Node.js, Python, FastAPI, REST and GraphQL APIs, WebSockets Databases: PostgreSQL, Supabase, Redis, MongoDB SaaS architecture: multi-tenant, tenant isolation, RBAC, Stripe billing, admin dashboards Cloud and DevOps: AWS, Docker, Vercel, CI/CD, monitoring Security and compliance: OAuth2, JWT, encryption, audit logs, HIPAA-aware builds, KYC/AML flows Integrations: Stripe, Plaid, open banking APIs, QuickBooks, Xero, Twilio, CRMs, ERPs Industries: AI SaaS, AI agents, document AI, RAG, FinTech, open banking, healthcare, B2B SaaS, startup MVPs, construction tech, legal tech, sales and CRM automation, voice AI, recruiting

What does an API integration developer do?
An API integration developer enables disparate software applications to share data and work together seamlessly. Think of them as a universal translator for your software, helping your CRM talk to your marketing automation tool or your e-commerce platform sync with your inventory system.
By connecting the tools you already use, these technical professionals build the bridges that help automate your business processes and can help eliminate manual data entry and reduce errors.
A developer's day-to-day work often involves:
Designing connections. Creating the blueprint for how different platforms will exchange information.
Implementing integrations. Building the actual connections that allow your software to communicate.
Troubleshooting issues. Finding and fixing problems when data doesnโt transfer correctly or a connection breaks.
Maintaining performance. Keeping integrations running efficiently and securely as your business grows.
Documenting processes. Creating clear guides so your team can understand and manage its connections in the future.

Define the primary goal of the integration, like automating a workflow or syncing customer data
List any required technical skills, such as experience with REST APIs or specific authentication methods
Give your timeline and budget expectations

2. Review proposals and evaluate technical expertise
Taking a structured approach to reviewing proposals will help you move efficiently from a large applicant pool to a focused shortlist.
Have Uma give instant video interviews and side-by-side comparisons
Use Upworkโs filters to find candidates by rate, location, and experience
Review proposals for signs that the candidate has understood your job post and has the skills to meet your needs
Check portfolios for case studies or examples of past work that are relevant to your needs
Read reviews from previous clients to gauge a developer's reliability and quality of work
3. Interview your top choices
Quick video interviews give you the chance to ask any questions you have left for your top candidates, and to get a feel for what a collaboration with them might be like.
Schedule and conduct interviews within Upwork messaging to get instant transcripts and summaries from Uma
Ask the candidates to walk you through past work from their portfolio, focusing on aspects that are similar to your project and challenges they overcame
Discuss each candidateโs typical process for approaching an integration project, looking for signs of solid methodology and planning
Ask questions designed to showcase the candidateโs technical depth, for example about how they handle rate limits, authentication issues, and errors
To prepare for your conversations, consider reviewing common interview questions for freelancers.
4. Define scope and begin work
Once youโve found the right person, you can send a contract directly through the Upwork marketplace. A solid contract protects both parties and helps collaborations be successful from beginning to end.
Use Upwork's contract workroom, messaging, and payment protection for secure collaboration
Choose fixed-price contracts for projects with clear deliverables, such as implementing a single API connection or basic data-sync setup
Break large projects into milestones, such as planning, development, implementation, testing, and debugging
Choose hourly contracts for ongoing work or projects without clear deliverables, such as performance monitoring, bug fixes, and ongoing optimization
Once the contract has started, be sure to give the integration specialist everything they need to succeed, including the appropriate access and permissions to service accounts, developer sandboxes, and staging and production environments.
