Detailed answers to what these services actually mean, the technologies involved, and how they help your business.
AI development services cover everything from adding a single AI feature to building a full agentic AI system. I build AI agents that can reason, plan, and use tools to complete multi-step tasks autonomously — using frameworks like LangChain, LangGraph, CrewAI, and AutoGen. This includes tool-calling and function-calling agents, multi-agent orchestration, ReAct and chain-of-thought reasoning, memory systems, and human-in-the-loop guardrails.
If you need to build an AI agent, integrate ChatGPT (OpenAI API), Claude (Anthropic API), or Gemini into your product, or ship an autonomous workflow, these are core specialties. I currently lead AI development on a production agentic AI SaaS platform.
LLM application development turns large language models into reliable product features. With RAG (Retrieval-Augmented Generation), I connect your documents, databases, and knowledge to an LLM so answers are accurate, grounded, and cited — reducing hallucinations. This uses vector databases (Pinecone, Weaviate, Qdrant, ChromaDB, pgvector), embeddings, hybrid search, reranking, and prompt engineering with evaluation.
Common builds: a RAG chatbot for customer support, an internal knowledge assistant, a document Q&A tool, or a voice AI agent. Chatbots can live on your website, WhatsApp, or inside your app.
Generative AI services add creative and media capabilities to your product: text-to-image generation (ComfyUI, Replicate, FAL.ai), speech-to-text and text-to-speech (TTS), real-time transcription, OCR, face swap, and video/audio AI. I build the reliable GPU inference pipelines (RunPod, cloud GPUs) and queues needed to run these at scale in production.
Custom software development means software built around your exact business logic — internal tools, admin dashboards, enterprise portals, and data pipelines. On the backend, I design scalable APIs and microservices with FastAPI, Django, and Node.js, using PostgreSQL, Redis, and MongoDB. This covers REST and GraphQL APIs, event-driven architecture (Kafka, Celery), authentication (JWT/OAuth 2.0, RBAC), and performance/latency optimization.
Web application development and website development deliver fast, modern, SEO-friendly experiences with Next.js, React, and TypeScript on the frontend and Python/Node on the backend. For founders, SaaS MVP development gets you to launch quickly — with authentication, Stripe/PayPal billing, multi-tenancy, usage/credit systems, and AI features baked in. Ideal if you want to build a SaaS, launch an MVP, or add AI to an existing web app.
Business process automation replaces repetitive manual work with reliable, always-on systems: scheduled jobs, webhooks, queues, and event pipelines. I handle API integration with tools like Stripe, CRMs (HubSpot, Salesforce), and internal services, plus notifications and reporting. Everything ships with cloud & DevOps best practices — Docker, Kubernetes, CI/CD (GitHub Actions), AWS/GCP, and monitoring with Sentry, Prometheus, and Grafana.

Straight answers to the questions clients most often search before hiring.
A production AI agent or RAG system starts at $1,999, and an AI chatbot integration starts at $999, depending on scope, data sources, and integrations. You can also work hourly (from $25/hr) or on a monthly retainer (from $1,899). Every quote is transparent and milestone-based.
Yes. I integrate OpenAI (ChatGPT/GPT-4o), Anthropic (Claude), Google Gemini, and open-source models (Llama, Mistral) into existing products — with streaming, function calling, RAG grounding, rate limiting, and cost controls built in.
A focused SaaS MVP typically takes 4–10 weeks depending on features. It includes authentication, billing (Stripe/PayPal), multi-tenancy, an admin dashboard, and AI features where relevant — built production-ready so you don't have to rewrite later.
I build RAG chatbots for customer support that answer from your own documents and data using vector search, hybrid retrieval, and reranking to stay accurate and cited. They deploy to your website, WhatsApp, or app.
Start with one high-value use case — a chatbot, a RAG knowledge base, or a generative feature — and integrate it without disrupting your current codebase. I assess feasibility in a free consultation and deliver a clear, phased plan.
Yes. A common stack is Next.js + React (TypeScript) frontend with a FastAPI (Python) backend, PostgreSQL, and Redis — deployed with Docker and CI/CD. I own the whole stack from database to UI to deployment.
Yes. I build 24/7 business automations — scheduled jobs, webhooks, queues, and integrations with Stripe, CRMs, and internal APIs — with monitoring and reporting so they run reliably without manual effort.
