🔹 Stop hiring developers. Hire someone who understands your product. I build and scale SaaS platforms end to end: Next.js and React on the front, Node.js and Python (FastAPI/Django) on the back, with Stripe, PostgreSQL, and AWS behind them. The kind of product that doesn't break after launch. If it involves APIs, dashboards, subscriptions, integrations, or AI features, I've probably built it before. What I Build Most Often • SaaS platforms (multi-tenant architecture) • Backend APIs (FastAPI, Django, Node.js/Express) • Integrations (OAuth, webhooks, third-party services, CRMs) • Automation & background workers • Analytics dashboards & admin panels (React / Next.js) • Data processing pipelines • Cloud deployments on AWS Why Clients Hire Me Many projects fail after MVP because the backend wasn’t designed for growth. I design for: 1. clean architecture 2. predictable scaling 3. maintainability 4. faster future features So you don’t need to rebuild in 6 months. Recent Work ✔ Built medical platform MVP (Node.js + React), production ready ✔ Designed military social platform infrastructure (Flask + AWS + Docker) ✔ Created organization-wide email compliance & analysis system (OAuth integrations) ✔ Built IoT monitoring platform with real-time device data ingestion ✔ Developed automation workflows & analytics dashboards Tech Stack 1. Backend Python (FastAPI, Django, Flask) Node.js (Express, NestJS) REST APIs, Webhooks, OAuth 2. Frontend React, Next.js, Vue Tailwind, Material UI 3. Data & Infrastructure PostgreSQL, Redis, MongoDB AWS, Docker, CI/CD Large dataset processing & reporting If you need someone who can own both the architecture and implementation, message me before hiring multiple developers.

Java sits at the center of the platforms I build. Spring Boot runs the backend services and APIs, handling business logic, data access, and the core behavior of the system. Many of these platforms pair a Spring Boot backend with Angular on the frontend, forming structured web applications such as internal dashboards, operational platforms, and SaaS systems used by teams every day. Angular provides the application interface while the Java backend manages services, data, and integrations behind the scenes. Python also comes into play when automation or data workflows are needed. Small services and scripts written in Python handle background tasks, integrations, and operational processes that support the main platform. Java and Spring Boot handle the backend services, Angular runs the platform interface, and Python supports automation and background tasks.

Drowning in legacy .NET modernization, broken LLM pipelines, RAG accuracy issues, or an AI SaaS architecture that can't scale? I build and ship production-ready AI systems, full-stack platforms, and LLM integrations that actually work in the real world. Top Rated Plus, 100% Job Success, 4,830+ hrs, $200K+ earned, 30 five-star reviews, 3x to 10x performance gains delivered. Most clients come to me tired of one of these: • An AI chatbot that makes things up because it isn't grounded in their real data • Hours lost every week to manual work and reporting a machine should handle • A legacy .NET app that's expensive to run and too risky to touch • A great Figma design still sitting unbuilt, or coded badly by someone else • A database and app that crawl as data and traffic grow • AI that looked great in a demo but solves nothing in production I've fixed every one of these, more than once. Here's how I'd help you. 1) AI chatbots, agents & RAG Chatbots grounded on your own data using RAG, LangChain, and vector databases (Pinecone, pgvector), so they answer from your content, not their imagination. GPT-4, Claude, Gemini, with tool use and memory. For your website, Shopify, or WordPress. An AI LMS I built answers in under 200ms. 2) AI automation & Power BI dashboards Workflows that handle the busywork: lead handling, outreach, data, and reporting, built in n8n, Zapier, or Power Automate, plus live Power BI dashboards for your KPIs. A B2B platform I built sends 500+ outreach sequences a day using GPT-4, Playwright, and Celery. 3) Legacy .NET modernization & Azure migration .NET Framework to .NET Core, onto Azure, with documented cost and performance gains. 10+ legacy apps migrated, no scary big bang rewrite. Backends in ASP.NET Core and FastAPI, 100+ APIs, CQRS, DDD, event driven microservices, clean architecture. 4) Figma to React & Next.js Pixel perfect, fully responsive frontends in React 18 and Next.js, hand coded with TypeScript and Tailwind, cross browser tested. Also Angular and Blazor, with real time features via SignalR and WebRTC. 5) Database & query optimization Slow queries fixed with execution plan analysis and proven before/after benchmarks across MySQL, MongoDB, PostgreSQL, and SQL Server. Indexing, query rewrites, schema review, and Redis caching where it helps. 6) Slow app made fast I profile the real bottleneck, queries, caching, code, or architecture, then fix it for measurable 3x to 10x gains across .NET, React, and Node.js. Integrations are a core strength, 50+ delivered: SAP, Microsoft Dynamics, NetSuite, Odoo, QuickBooks, SPS Commerce, EDI (X12, EDIFACT), UPS, FedEx, USPS, Interactive Brokers, Fidelity, Schwab, Shopify, Stripe. Proof at scale: a multi tenant SaaS analytics platform processing millions of data points daily on Azure, and a logistics system handling 10,000+ shipments a day. Cloud and DevOps: Azure App Services, Service Bus, Functions, Kubernetes, CI/CD via Azure DevOps. Why clients stay and come back: • Plain language updates, so you always know status, risk, and what is next • I solve the business problem, not just the ticket • Production ready from day one: documented APIs, parameterised queries, typed frontends, CI/CD, no rework • UK based, responsive across US and European business hours Need an AI chatbot, automation, a .NET rebuild, a Figma to React build, database tuning, or a slow app made fast? Send me the brief and I will tell you exactly how I would tackle it. Available for long term contracts and focused sprints. Skills: .NET Core, C#, ASP.NET Core, Python, FastAPI, React, Next.js, Angular, Blazor, TypeScript, AI chatbot, AI agent, RAG, LLM integration, AI integration, OpenAI GPT-4, Claude, LangChain, Pinecone, AI automation, n8n, Power BI, Azure migration, microservices, API development, ERP integration, EDI, database optimization, MySQL, MongoDB, PostgreSQL, performance optimization, Redis.

If your backend is slow, your APIs keep breaking under load, or your AI features feel bolted on instead of built in, that's usually where I come in. I build Django and FastAPI backends on AWS for SaaS and AI products that need to stay fast under real user load, not just pass a demo. Most of my work is either fixing slow APIs and deployment bottlenecks or shipping new backend features (REST APIs, async jobs, LLM/RAG integrations) for teams that outgrew their first architecture. I'm a senior Python backend developer based in India, with 8+ years, top-rated, and 100% job success. What I work on day to day: ★ REST APIs and backend services (Django/DRF, FastAPI, Flask when it fits) ★ Cloud deployments on AWS: EC2, S3, RDS, Lambda, Docker, CI/CD pipelines ★ Async and background jobs: Celery, Redis, RabbitMQ for queues, reports, notifications ★ AI and LLM integration: RAG workflows, chatbots, automation pipelines (OpenAI, Gemini, Grok APIs; not just prompt wrappers) ★ Backend refactoring: slow queries, messy codebases, deployments that break every release ★ Microservices where it makes sense: not microservices for the sake of it A few projects I've led or built recently: Astrosure.ai: AI-powered astrology platform from scratch. I led the backend: Django and FastAPI services, birth chart processing, dosha/dasha rules, and the Agastyaa chatbot with LLM integration. Deployed on AWS with Docker and CI/CD on EKS. HerKey (herkey .com): India's largest career platform for women. Built scalable APIs for job matching, session booking, and notifications. Django REST Framework, MongoDB, Elasticsearch, Kubernetes on AWS. We cut incident triage time by around 40% after improving monitoring and deployment flow. Riyaah (riyaah.sa): Beauty e-commerce platform in Saudi Arabia. Backend for product catalog, orders, and payment flows. Django, PostgreSQL, AWS. Before Upwork, I worked with Capgemini (banking/ANZ), Flooid, Keuro Digital, and Bricksteel, mostly backend, team lead, and client-facing delivery. I also run Sparkscribe Technologies for larger or long-term engagements where you need more than one developer. On Upwork you work with me directly. For larger scopes, I may involve senior developers from my company under my technical lead, only with your approval and with me owning architecture and delivery. How I usually work with clients: I keep communication straightforward, regular updates, and clear ETAs, with no disappearing mid-sprint. I've managed small teams (up to 10 devs), done code reviews, and set up CI/CD and monitoring so releases don't turn into firefights. Most of my Upwork clients mention responsiveness and clean delivery in their reviews. If you need someone who can own the backend end-to-end architecture, APIs, cloud, AI integration, and production stability, send me a message with a short description of what you're building. I'll reply with honest thoughts on scope and how I'd approach it.
