I turn vague product ideas into shipped SaaS and mobile apps backends that scale, UIs that feel fast, and AI features that belong in production, not demos. I’m a full-stack SaaS and mobile developer with 5+ years building and maintaining production systems for startups and businesses MVP through growth, refactors, and the messy middle when usage jumps. What I do best • SaaS web apps: greenfield builds or improving what’s already in market • Mobile: Flutter (iOS & Android) integrated with secure, scalable backends • APIs: REST and GraphQL, designed so the product doesn’t paint itself into a corner • Performance and reliability: debug, optimize, and scale as real traffic shows up • Ownership: idea → architecture → implementation → deployment (not “handoff and vanish”) Frontend - web apps & dashboards React, Next.js, Nuxt.js, Vue.js · Tailwind CSS · TypeScript, JavaScript · Redux, Redux Toolkit, Zustand · GraphQL (Apollo Client) · Jest, Cypress Backend & APIs Django · Ruby on Rails · FastAPI · Express (TypeScript) · Go (Gin, GORM) · REST & GraphQL (Hasura, Apollo Server) Mobile Flutter · iOS & Android · integrated with SaaS backends (auth, contracts, versioning done properly) Database PostgreSQL · MySQL Cloud & delivery Google Cloud Platform (GCP) · Docker & Docker Compose · CI/CD · environment-based configuration & secrets · monitoring, profiling, and performance work AI in products (practical, shippable) LLM integrations and product features grounded in your data where it matters structured outputs, streaming UX, guardrails so “AI” doesn’t mean “unpredictable demo.” Tools & workflow GitHub · VS Code · Jira · Trello · Meet / Zoom · clean commits, readable code, predictable delivery Why teams hire me I’m product-first, communicate in plain updates with realistic timelines, and I’m comfortable owning integrations, debugging, scaling, and data-heavy problems without drama. Experience SaaS platforms, financial systems, EdTech, automation, and high-performance dashboards—shipping software that stays fast and stable when it matters. Languages English — fluent · Amharic — native If you’re launching a SaaS product, shipping a mobile app, or fixing a system that’s outgrowing its first version send a message with goals, stack, and timeline. I’ll tell you what I’d do first and whether I’m the right fit.

Hey, I'm Prateek, a Top-Rated Full-Stack Developer with $60K+ earned and 1,200+ hours completed on Upwork, I am helping startups and businesses build AI-powered SaaS platforms and agentic systems that actually ship to production. I specialize in the intersection of full-stack SaaS engineering and applied AI: LLM systems, agentic architecture, and the product decisions that make them reliable, not just impressive in a demo. That means designing how an agent reasons, plans multi-step actions, and uses tools, not just wiring up an API call and calling it AI. Since 2022, I've worked with global clients to build custom SaaS platforms, AI agents, REST APIs, and automation systems that solve real business problems. Clients tend to stick around; a few whiteboard sessions in, and I'm usually treated like part of the internal team, which is probably why most of my Upwork engagements run 18 months to 3 years. What I can help you with: - AI Agent & Agentic System Development - SaaS MVP Development, idea to production - Context Engineering - Retrieval Augmented Generation (RAG), Embeddings & Vector Search - AI Chatbot Development - Django / Python Backend Development - React / Next.js Applications - REST API Development - Automation Systems & AI Workflows - AWS, Docker & Cloud Deployment - Startup & Enterprise SaaS Architecture A few of these live in my portfolio below: an AI recruiter that interviews candidates itself, a maintenance agent that plans repairs from live floor plan and documentation data, a knowledge platform that reasons over a company's internal knowledge base. I also build fast. My workflow runs on AI native coding tools like Claude Code, so I can take an idea to a working MVP in weeks, without skipping architecture, tests, or security to get there. Tech Stack: Python, Django, Django REST Framework, React, Next.js, Node.js, TypeScript, PostgreSQL, OpenAI API, Anthropic API, LangChain, Vector Databases, AWS, Stripe, Celery, Docker, Git. If you're building an AI product, or want to add real agentic capability to one you already have, send me a message and tell me what you're trying to build. Happy to jump on a quick call and think it through with you.

Django Python Developer specializing in scalable SaaS backends, AI automation, and REST APIs. I rescue messy inherited Django codebases and build clean, production-ready systems with React, PostgreSQL, Stripe, and OpenAI integrations. Does your Django project feel chaotic from multiple developers, with slow queries, broken flows, or missing automation? Or do you need a robust new SaaS platform with role-based access, payments, and AI features built from scratch? I help startups and businesses turn unreliable backends into reliable, scalable systems that drive growth. I step into existing Django projects, audit, refactor, debug, and extend them without breaking functionality. I also architect clean MVPs with best practices that future developers will love. How I Deliver Results for You: 🔹 Django Code Rescue & Maintenance – Fix inherited codebases, optimize PostgreSQL/MySQL queries, resolve race conditions, and implement Celery + Redis for background tasks and scheduled jobs. 🔹 SaaS & Multi-Vendor Marketplace Development – Build role-based platforms (clients, suppliers, admins) with secure auth (2FA), Stripe subscriptions, clean REST APIs, and CRM-ready architecture. 🔹 AI Automation & Integrations – Integrate OpenAI, LangChain, RAG, Google Sheets API, and browser automation (Playwright). Automate data processing, workflows, and manual tasks to save your team 20+ hours/week. 🔹 Full Stack & Deployment – Work with React.js, HTML/CSS/JavaScript, Docker, AWS. Handle OAuth, webhooks, third-party APIs, and containerized deployments. What You Can Expect: ✅ Respect for your existing code and timeline ✅ Daily updates with clear communication ✅ Clean, documented, testable code ✅ Long-term partnership mindset (many clients keep me for 6–12+ months) ✅ Proactive problem-solving and on-time delivery Technical Expertise: Python, Django, Django REST Framework, PostgreSQL, MySQL, MongoDB, React, HTML/CSS, JavaScript, Celery, Redis, Docker, AWS, Stripe, OpenAI, LangChain, RAG, Google APIs, Git, OAuth, Webhooks.
