Ashish J.

I help SaaS teams turn backend and AI features into production-ready systems—secure, scalable, reliable, and maintainable. I’m a Senior Backend & AI Systems Engineer with 7+ years of experience building production systems using Python, Go, Node.js, PostgreSQL, and AWS. My work is best suited to SaaS founders and small engineering teams that need senior backend ownership without hiring another full-time engineer. I can help when you are: 🚀 Taking an AI feature or agent from prototype to production 🧠 Building a new backend feature or custom AI workflow 🔄 Replacing a fragile no-code or low-code prototype with maintainable infrastructure ⚙️ Improving reliability, performance, security, or cloud architecture 🔐 Integrating AI safely with customer data and business systems 📈 Scaling a SaaS backend that is becoming difficult to operate BACKEND & SAAS ENGINEERING ✅ Production APIs and microservices using Python, Go, and Node.js ✅ SaaS architecture, multi-tenant systems, and backend workflows ✅ Authentication, authorization, role-based access, and permissions ✅ PostgreSQL schema design, query optimization, and performance tuning ✅ Event-driven systems, Kafka, WebSockets, and asynchronous processing ✅ Stripe subscriptions, billing systems, webhooks, and third-party integrations AI SYSTEMS & AGENTS 🤖 OpenAI and LLM integrations with structured outputs 🧩 Custom AI workflows and tool-using agents 📚 Retrieval and data-processing pipelines 🧪 Evaluation, validation, fallback, and error-handling systems 🛡️ Human approval flows and controls for sensitive agent actions 🔍 Observability, auditability, and production reliability for AI features 🔧 Productionizing workflows that have outgrown n8n, Make, Zapier, or similar platforms I do not focus on basic platform automation or thin chatbot wrappers. My work begins where an AI workflow needs custom business logic, stronger security, reliable data access, testing, observability, or owned backend infrastructure. CLOUD & PRODUCTION INFRASTRUCTURE ☁️ AWS architecture and deployment 🐳 Docker and containerized development environments 🔁 CI/CD pipelines and automated releases 🔐 Secure configuration and environment separation 📊 Scalable, fault-tolerant production architecture ⚡ Performance, reliability, and cloud-cost improvements HOW I WORK 🏗️ PRODUCTION-MINDED I design for real users, failures, security, maintenance, and future change—not only for a successful demo. ⚖️ PRACTICAL ENGINEERING I balance clean architecture with delivery speed and business priorities. 💬 CLEAR SCOPE & COMMUNICATION You receive structured updates, documented decisions, predictable milestones, and a clean handover. 🤝 LONG-TERM OWNERSHIP After a successful fixed-scope project, I can take responsibility for a clearly defined backend or AI subsystem through an ongoing monthly engagement. GOOD PROJECT FIT ✅ AI production-readiness work ✅ Custom AI workflows and agents ✅ Backend features for SaaS products ✅ API and system integrations ✅ Performance and reliability improvements ✅ Architecture modernization ✅ AWS deployment and production hardening If your SaaS product needs a dependable backend or an AI feature that is ready for real customers, send me a message with: 📌 Your current system 📌 The problem you are facing 📌 The outcome you need
