AI built into real software
I build LLM applications that work on a business's own data: RAG with embeddings and Qdrant vector search, AI assistants that respect each user's permissions, and LangChain / LangGraph agents that call tools, route work between specialist agents and ask before they change anything — on OpenAI, Anthropic, Gemini, OpenRouter or open-source models.

AI Chatbots
Customer-facing chatbots grounded in your own data — docs, catalog, tickets, DB — for web, WhatsApp and mobile. Ingestion, chunking, embeddings, vector search, reranking and cited answers, so replies are accurate, not guessed.

AI Assistants
Assistants that live inside your product and help users get work done — drafting, summarising, searching, filling forms and answering questions with full context of the logged-in user's data and permissions.

AI Agents
Multi-step agents that plan, call tools and APIs, read and write to your systems, keep memory and stay inside guardrails — built with function calling and MCP, and orchestrated as complete agentic flows in LangChain and LangGraph — supervisor routing, specialist agents and human-in-the-loop steps.

AI Workflow Design & Automation
Designing the workflow first, then shipping it as LLM-powered pipelines for the repetitive work: lead qualification, document extraction, classification, scraping, email auto-replies and back-office automation with Python and n8n.

LLM Pre & Post Training
Hands-on with the model side: dataset prep, small-model pretraining fundamentals, SFT / LoRA fine-tuning, evaluation and serving open models when an API model isn't the right fit — including Sutradhar 3B MoE, my own English–Telugu base model pretrained and published on Hugging Face.

AI-native engineering workflow
I combine detailed architecture planning, AI-assisted implementation, automated testing, security review and engineering oversight to shorten delivery cycles while maintaining code quality and maintainability.
- 1Architecture planData model, boundaries and acceptance criteria are written before any code.
- 2AI-assisted implementationCoding agents draft the implementation against that plan.
- 3Automated testingTests and production builds run on every change.
- 4Security reviewAuth, input validation, secrets and dependencies are checked before release.
- 5Engineering oversightI review every change — the tools speed up delivery; they don't replace the engineering.

ARCHITECTURE
I architect complete products — not just screens
Every build is planned as one system: the clients people use, the API and business rules behind them, the data model, the AI layer and the infrastructure it runs on — so features, security and scale are designed in, not bolted on.
- Tenancy decided up front — a shared database or a database per tenant, on one domain or many.
- Permissions enforced on the server, with an audit trail on business records.
- AI that reads only what the signed-in user may see, and asks before it writes.
- Containerised deployments that are reproducible on a VPS or in the cloud.

SERVICES
What I can build for you
From a single web app to a multi-tenant SaaS platform with AI — planned, built, integrated and deployed by one senior engineer.
Custom Web Application Development
Business web applications built around your real workflows — portals, dashboards, booking and commerce flows — shipped to production, not left as prototypes.
SaaS Product Development
Multi-tenant SaaS with tenant isolation, subscriptions and billing — on one shared database or a database per tenant, across one domain or many.
Mobile Application Development
Android and iOS apps in Flutter and React Native, sharing APIs with the web platform and taken all the way through Play Store and App Store release.
AI & RAG Development
AI assistants, retrieval over your own data and agent workflows with LangChain, LangGraph and Qdrant — grounded answers, permission-aware and cost-controlled.
Backend & API Development
REST APIs and backend services in Node.js/Express, Laravel or FastAPI, with authentication, payments, messaging and third-party integrations done properly.
Enterprise Software Development
Internal systems for operations, finance and HR — approval chains, audit trails, multi-organization access and the reporting teams rely on every day.
Software Architecture
Architecture planning before code: stack selection, data modelling, tenancy strategy and documentation, so the product can grow without a rewrite.
DevOps & Deployment
Production deployment on a VPS or AWS with Docker, Nginx, SSL, DNS and CI/CD — plus server migrations and ongoing care after launch.
WordPress Development
Custom WordPress and WooCommerce sites — themes, plugins and Elementor or WPBakery builds for businesses that need to publish and sell on their own.

ABOUT
Senior Full-Stack, SaaS & AI Developer — and the builder behind TechDino. I design and ship complete products, then turn the proven ones into ready-to-launch software.
For 12+ years I've built web, mobile and desktop applications end to end — React and Next.js front ends, Node.js, Laravel and FastAPI backends, and the admin panels, APIs, integrations and deployments that hold them together. My career runs from web design and SEO in 2013, through five years of WordPress, PHP and API work at Crenov8, to senior full-stack roles leading teams and architecting SaaS platforms.
Under TechDino I've built 32 deployment-ready products — CRM, HRMS, ERP, warehouse, school, clinic, e-commerce and real-estate platforms — that businesses can launch under their own brand and extend. 8 of them ship with built-in AI assistants and agents.
I can deliver a complete application on my own — architecture, database design, development, payments and third-party APIs, DevOps (AWS, VPS, Docker, DNS) and Play Store / App Store release — or lead a team through it. AI coding tools speed up the implementation; the planning, review, testing and security checks stay with me.
