12+ apps live on the App Store and Play Store — healthcare, fintech, education, food delivery, telehealth, and field services. Every one built end to end: architecture, UI, backend, third-party integrations, real device testing, and store submission. What I build: Flutter cross-platform apps (iOS + Android), Laravel backends, REST APIs, and FastAPI services. I work across the full stack — frontend through deployment. Where I've done this: DictateX — FastAPI backend with Whisper transcription, FHIR/TalkEHR integration, and automated SOAP note generation (live at qa.dictatex.ai) Azz Medical Associates — Flutter + Laravel + React.js appointment booking with real-time doctor availability (both stores + web) Capital Psychiatry Group — HIPAA-compliant telehealth app with video, scheduling, and insurance flows TeamMates, Hazir Hoon, Foodie Moodie — real-time features, live location, push notifications, VideoSDK Flutter (Bloc, Provider, GetX, MVVM) Laravel (REST APIs, Sanctum, Passport, Queues, Scheduler) FastAPI (Async APIs, Pydantic, SQLAlchemy) Node.js (Express, WebSockets) MySQL · PostgreSQL · MongoDB Firebase (Auth, Firestore, FCM) REST APIs · JWT/OAuth CI/CD Why Clients Work With Me ✅ End-to-end ownership — I've taken apps from wireframe to App Store approval, solo ✅ Real-time systems — chat, live location, video calls, and push notifications in production ✅ I test on real devices, not just simulators — before every client delivery ✅ Long-term mindset — most clients come back for Phase 2 ✅ HIPAA-compliant architecture — I've built two live telehealth apps with video, scheduling, and insurance flows I use AI tools (Claude, Cursor) daily — as a senior pair programmer, not a replacement for understanding. I test on real devices. I don't ship code I can't explain line by line. Stack I work with regularly: Flutter · Dart · Laravel · PHP · FastAPI · Python · React · Next.js · Node.js · REST APIs · OpenAI API · LangChain · LangGraph · WhatsApp Business API · VAPI · Twilio · Firebase · MySQL · PostgreSQL If you're building a serious mobile product and need someone who understands both mobile + backend architecture, let’s talk. 📩 Based in Pakistan (UTC+5), available for overlap with US and European clients.

Let's build something that delivers real results, not just another AI proof of concept.

Most backends are functional. The ones I build are production-ready, maintainable, and ready to integrate AI when your product needs it. I'm Andrew, a Python backend developer specialising in Django REST Framework and FastAPI. 16 contracts delivered on Upwork, every reviewed client gave 5 stars. Two production systems showcase the range: - Diba Fintech API (Django REST Framework, live in production). Lead engineer Alerechi Ordu: "a great asset to the team, consistently delivering high-quality work with strong attention to detail." - Doctor AI (Django 5 + Google Gemini API) — a health analysis platform with 23 custom system prompts across diagnostic categories. Live demo: andrewoduola.online/projects/doctor-ai Core services: - Django REST APIs: authentication (JWT, OAuth2, RBAC), serializers, admin panels, background tasks with Celery - FastAPI: async endpoints, Pydantic validation, OpenAPI docs, high-performance microservices - AI/LLM integration: Google Gemini, OpenAI API, LangChain, RAG pipelines, AI assistant backends, prompt engineering - Real-time features: Django Channels, WebSockets, Redis channel layer, event-driven systems - Database: PostgreSQL, MySQL, schema design, query optimisation, indexing - Infrastructure: Docker, Redis, AWS (EC2, S3, RDS), CI/CD pipelines How this works in practice: The first conversation isn't about the spec, it's about what you're actually building and why. You get a clear plan with trade-offs flagged before any code is written, regular check-ins so nothing drifts, and clean, tested, documented code as the baseline. Disappearing mid-project isn't a thing that happens. Every reviewed client on Upwork has mentioned communication specifically, not as a side comment, but as a standout. If your backend needs to be production-ready, not just functional, there are two ways to start: - Send your spec, and you'll get a written technical plan back within 4 hours, or - Book a 15-minute call, and we'll walk through your stack and constraints together. Whichever fits your week. - Andrew (Drew), Lagos. Available now, working across US, EU, and APAC time zones.

✅ Top Rated FullStack expert Why Work With Me? 🔹 Top-Rated Focus: I dedicate 100% attention to one project at a time, ensuring quality, timely delivery, and clear communication. 🔹 10+ Years of Impact: Built apps serving 1M+ users, optimized performance by 70% for Fortune 500 companies, and led cross-functional teams. 🔹 Client-Centric Approach: I translate ideas into intuitive, scalable solutions—whether it’s a startup MVP or enterprise-level system. I build the backend infrastructure that AI products run on. Over the past 12 years I have shipped production systems across fintech, insurtech, energy, and AI — from a mobile app with 500K+ downloads in Southeast Asia to a custom RAG pipeline currently running in production at a Stockholm-based AI startup where I serve as Lead Developer. My core work right now sits at the intersection of cloud infrastructure and AI systems — specifically FastAPI backends, custom retrieval-augmented generation pipelines, AWS architecture, and Kubernetes. I have built RAG systems both with LangChain and completely from scratch without any framework, depending on what the project actually needs. On the infrastructure side I work across the full AWS stack — ECS, Lambda, RDS, VPC, IAM, CloudFront — and I am currently leading a Kubernetes migration with zero-downtime deployment strategy at my company. What I do not do is take on five projects at once and disappear. I work with one or two clients at a time, communicate daily, and treat your codebase like my own. If you are building an AI product, a data-intensive backend, or need someone to take ownership of your cloud infrastructure — I am straightforward to work with and I know this stack deeply.

I build secure internal AI copilots and enterprise search systems that connect your documents, CRM, databases, Slack, email, and internal tools so your team can get answers, trigger workflows, and automate repetitive work with confidence. If you need more than a chatbot demo, I can help you ship a production-ready AI system with grounded answers, citations, clean tool integrations, human handoff where needed, and clear evaluation. What I build: • Internal copilots for operations, support, sales, and knowledge teams • Enterprise search / RAG systems over SOPs, policies, contracts, tickets, product docs, and databases • MCP and API integrations for CRMs, helpdesks, Slack, email, Postgres, and internal tools • Workflow automation that updates records, routes tasks, sends follow-ups, and closes manual loops • Evals, tracing, and observability so answer quality improves over time • FastAPI backends, Python services, dashboards, and deployment-ready architecture Common outcomes: • Faster internal answers for teams • Fewer repetitive support tickets • Better lead routing and cleaner CRM workflows • Safer document Q&A with citations • Less manual operational work across disconnected systems I work with: Python, FastAPI, OpenAI, Claude, MCP, PostgreSQL, pgvector, Qdrant, Weaviate, Langfuse, n8n, webhooks, REST APIs, React, and Next.js I do not focus on AI theatre. I focus on useful systems that are measurable, maintainable, and tied to real business workflows. If you already know your bottleneck, send me the workflow and tool stack. If you do not, I can help you design the shortest path to a reliable internal AI system.

Top Rated Plus with 10+ years of experience, $100K+ earned on Upwork, 3000+ Upwork hoours I specialize in turning business problems into production-ready systems using Python, Node.js, React, and modern AI infrastructure. Whether you need an intelligent backend, a polished frontend, or the full product end-to-end, I design and ship systems that real users can actually depend on. On the AI side, I build RAG pipelines, LLM agents, AI automation workflows, and document processing systems using OpenAI, Claude, Gemini, LangChain, LangGraph, vector databases, and embedding-based retrieval. I've delivered KYB verification workflows, AML data systems, AI file organization tools, AI-powered construction estimation, and ETL pipelines connected to real business data. On the full stack side, I build production backends with Python/FastAPI and Node.js/Express, and production frontends with React and Next.js — connected to PostgreSQL, MongoDB, REST APIs, CRMs, and cloud infrastructure on AWS with Docker. I don't outsource the frontend or treat it as an afterthought. I build the full product. What I can build for you: RAG chatbots trained on your private business data LLM agents with tools, memory, multi-step workflows, and guardrails AI automation systems connected to your APIs, CRMs, databases, and dashboards Python/FastAPI and Node.js backends for production AI applications Full stack SaaS products with React, Next.js, FastAPI, Django, PostgreSQL, MongoDB, Docker, and AWS AI document processing, OCR, data extraction, and structured output pipelines Web scraping and ETL systems at scale OpenAI, Claude, Gemini, Ollama, LangChain, LangGraph, and vector database integrations My edge is the full picture. I understand the business problem, design the data layer, build the AI workflow, expose it through a clean API, and wire it up to a frontend your users can actually use. No handoffs. No gaps between layers. If you need someone who can own the entire stack and ship a reliable, maintainable product — let's talk.
