Anil K.

AI Engineer and Fractional CTO with 14+ years of building production AI and SaaS products. I design and build AI agents, RAG and LLM features, and the full-stack SaaS platform around them, from architecture to launch. Clients bring me in when the problem is bigger than "just write the code": when AI, product architecture, data, security and scale all have to work together. I lead a small team at Coretus, so you work with one accountable engineer who can bring in mobile, design and QA when the project needs them. ◆ AI ENGINEERING: AI AGENTS, RAG & LLM APPS Tool-calling and multi-step agents with human approval steps, document search that answers with sources, evaluation, observability and cost control. OpenAI, Claude, Gemini, LangChain, LangGraph, MCP, pgvector, Pinecone, Qdrant. What matters is what happens after the demo: answer quality, reliability, latency and cost. ◆ FULL-STACK AI DEVELOPMENT The AI feature and the product around it: Python/FastAPI or Node.js backends, React/Next.js frontends, PostgreSQL, Redis, authentication, roles and third-party integrations. ◆ SAAS DEVELOPMENT From MVP to scale: multi-tenant platforms, subscriptions and billing, admin dashboards, APIs, AWS and GCP with Docker and CI/CD. ◆ FRACTIONAL CTO & SOLUTION ARCHITECTURE System design, technical roadmaps, stack choices, technical debt and team guidance, so the right decisions are made before money goes into the wrong build. ◆ FINTECH, QUANT & ALGORITHMIC TRADING I built AlgoSuccess, an AI-powered quantitative analysis app for traders, live on the App Store. It's where my two specialities meet: AI engineering and a decade of trading systems. My Upwork history includes 50+ MT4/MT5 Expert Advisors, strategy backtesting and optimisation projects in MQL4/MQL5 and Python, with consistently 5-star feedback. I bring that domain knowledge to fintech platforms, trading tools, quant analytics, and payment and financial-data integrations. RECENT WORK • Leobrain: an AI recruitment platform, built with my team at Coretus (AI agents, RAG, full-stack SaaS) • AlgoSuccess: an AI-powered quantitative analysis app for traders (iOS and Android) • Caletus: a meeting and scheduling SaaS, built with my team at Coretus • TalkMax: a secure chat, calling and meeting app, built with my team at Coretus (real-time, mobile and web) • EAT: an AI meal and nutrition app, built end to end with my team (5-star, long-term contract) • Fractional CTO and SaaS architecture for enterprise software clients (5-star) Over 14 years, my teams and I have contributed to systems for HSBC, Deloitte, Mastercard, PepsiCo, Nestlé, Airbnb and Bissell, most of it as an engineering partner on larger programmes. HOW I WORK I start from what your users need, build the smallest version that proves it on your real data, then grow it. If plain software solves the problem better than AI, I'll say so rather than add AI for its own sake. Tell me what you're building and where you're stuck, and I'll reply with how I'd approach it.
