I primarily work on four types of projects:
1) Crafting your AI Strategy
Expand your business vision with the latest tools and frameworks. Teach me about your industry, and I'll steer your AI journey from discovery through deployment—identifying opportunities, crafting your roadmap, and shaping a data-driven strategy that delivers measurable impact.
2) Automation and Intelligent Workflows
Transform time-sensitive, repetitive tasks into streamlined, AI-powered workflows—from lead validation and customer onboarding to compiling accurate, visually compelling reports and advanced analytics. I help boost efficiency, reduce manual effort, and scale your operations.
3) Conversational bots and Multi-Agent Systems
Engage users and help employees with text and audio based conversations. Whether for customer service, data scientists on top of internal DBs and training material, or compliance-based communication, our solutions act autonomously and collaborate seamlessly to get things done.
4) AI-Assisted Full Stack Development
Our team is trained to use AI judiciously during every stage of development. Vibe coding can go horribly wrong when in the hands of the uninitiated, but when you combine tools like Cursor with our engineering expertise, you get reliable new products and services faster than has ever been possible.
My portfolio has more examples, but in short, if you're looking to build specialized agents to perform enterprise-ready tasks, you'd be hard-pressed to find a more qualified developer anywhere on Upwork.
I'll be applying as an organization - krazimo (krazimo.com), so you'll get two world-class engineers (Mridul and I) working on your project, as well as a number of junior engineers to perform the smaller engineering tasks. You'll have full transparency into who's doing what, and our junior engineers work for approximately 2/3 our hourly rate.
Here's a little about my 11 years of experience.
Google (2019-2025)
I spent six years as a senior software engineer at Google.
My two major projects currently were
Admin AI Assistant: I'm worked as an LLM specialist on building a RAG solution to improve Google's customer service in our workspace Admin Console.
Gemini Reporting: Led a team of 10 people in building a large scale pipeline that can handle high QPS events on Gemini usage and report on value and RoI for our Gemini Product in Google Workspace.
Apart from these, I have designed, implemented and shipped many technically complex products at Google. They often involved coordinating efforts among large teams and always required me to adhere to the highest engineering standards. I hope I can bring this expertise to your company.
NLP Engineer (2016-2019)
Cofounded, Headed AI and built the prototype and MVP for Butter.ai, which raised $3M in seed funding and was eventually acquired by Box.
Worked on sentiment analysis problems for psychiatric chat centers (analysis user messages to flag dangerous situations)
Worked on text extraction and question answering problems for a company that helped health insurance providers answer complex questions related to a customer's coverage.
Mobile Engineer (2013-2015)
Worked on a number of apps for clients - including building the cleartax.in android application.
Worked at IBM as a software engineer on a MDM product that involved core android development (very low level control of services and permissions).
At the moment, this process is more about exploring the space and seeing what people are looking for in the world of AI, outside massive AI-centric companies like Google (my hourly rate is actually below my current salary, so you're getting a pretty great deal while I perform this exploration)!

Tech founders and CTOs hire me, a results-driven AI Engineer and Backend Developer , when they need to transition an unpredictable AI prototype into a secure, scalable, production-grade system.
Most AI projects stall because developers build fragile prompt wrappers that break under real-world traffic.
As a senior AI Engineer, I specialize in building robust Python backends, autonomous multi-agent architectures, and deterministic software engines designed to run reliably at scale. My AI systems are engineered for production, not demos.
Over the past eight years, I have engineered and deployed technical systems that translate directly into business value. As a Backend Developer and AI Engineer, I designed a cross-industry MVP in 2021 for the healthcare, real estate, and fintech sectors that successfully scaled into a commercial B2B SaaS platform currently generating over $7M in recurring ROI per annum, proof that strong Python-driven architecture and disciplined AI engineering deliver real outcomes.
𝗪𝗵𝗮𝘁 𝗬𝗼𝘂 𝗚𝗲𝘁 𝗪𝗵𝗲𝗻 𝗪𝗲 𝗪𝗼𝗿𝗸 𝗧𝗼𝗴𝗲𝘁𝗵𝗲𝗿
• Production AI & RAG Pipelines: As a dedicated AI Engineer, I implement advanced Retrieval-Augmented Generation (RAG) pipelines using custom chunking strategies, token optimization, prompt caching, and hybrid semantic search via OpenAI and Claude APIs. Every RAG system I build is optimized for accuracy, speed, and cost efficiency.
• Autonomous Multi-Agent Systems: Multi-step orchestration workflows built with LangChain, AutoGen, and MCP (Model Context Protocol) to handle continuous background monitoring and complex data execution, core capabilities every modern Backend Developer specializing in AI must master.
• High-Performance Backend Architecture: Fast, asynchronous REST APIs engineered with Python and FastAPI, keeping your probabilistic AI outputs strictly separated from exact financial or relational database logic. Clean Python architecture is non-negotiable at scale.
• Enterprise Infrastructure & MLOps: Containerized deployments using Docker, automated Infrastructure-as-Code (IaC) via Terraform, and continuous integration pipelines with GitHub Actions across AWS and Azure AI Foundry, built to support enterprise SaaS operations end to end.
• Full SaaS Core Frameworks: Secure relational database modeling (PostgreSQL, Supabase, SQL Server), OAuth/JWT authentication (Clerk, NextAuth), and multi-tenant subscription mechanics using Stripe, the complete SaaS stack, fully production-hardened.
𝗪𝗵𝘆 𝗜 𝗔𝗺 𝘁𝗵𝗲 𝗥𝗶𝗴𝗵𝘁 𝗙𝗶𝘁 𝗳𝗼𝗿 𝗬𝗼𝘂𝗿 𝗣𝗿𝗼𝗷𝗲𝗰𝘁
• Trench-Tested Technical Ownership: Having spent over eight years working between business clients and core development teams as both AI Engineer and Backend Developer, I don't need hand-holding. I design the database schemas, analyze response latencies, and minimize api token burn rates out of the box.
• Security & Compliance Frameworks: I understand how to handle AI data pipelines under strict operational guardrails, including HIPAA compliance and PHI data protection for healthcare SaaS software, and SOC2 readiness for fintech operations.
• Clean, Enterprise-Ready Deliverables: Every Python-engineered system I deploy features comprehensive automated testing (Unit/E2E), explicit error trapping, and structured operational runbooks so your internal engineering team can scale it smoothly.
• Full-Stack Fluency: While my core domain is AI backend engineering, optimization, and MLOps, my proficiency as a Backend Developer with React and Next.js ensures absolute alignment across your front-end asset publishing and user journey layouts , critical for polished SaaS products.
Whether your platform requires deep document intelligence with RAG and OCR pipelines, local open-source model serving via vLLM and llama.cpp, or deep third-party integrations with travel GDS, WhatsApp Business, or Meta/Google Ads APIs, as your trusted Backend Developer and senior AI Engineer, I build it to last in Python.

Most AI systems work in demos. Mine work in production.
I specialize in building agentic AI systems, multi-agent orchestration, and intelligent workflow automation for HealthTech, LegalTech, FinTech, and multi-tenant SaaS platforms.
Recent production systems include SANAM a multi-tenant agentic AI platform and JADA a full-stack AI-powered legal operations system serving US and Mexican law firms.
What I build:
. AI agents with scoped tools, guardrails, and auditable execution
. Multi-agent orchestration with LangGraph and LangChain
. Workflow automation event-driven, scheduled, and webhook-triggered via Temporal
. Human-in-the-loop systems via email, Slack, and approval flows
. RAG pipelines with chunking strategy, retrieval optimization, and citation flow
. LLM integration using OpenAI and Anthropic with structured, validated outputs
. Multi-tenant SaaS architecture with tenant isolation and role-based access
. API integrations via Composio Odoo, SAP, Slack, and custom connectors
How I work:
I don't start with prompts I start with system behavior.
→ How agents coordinate and hand off tasks
→ How workflows execute reliably under real load
→ How retrieval stays accurate as data grows
→ How outputs remain consistent when real users hit the system
This is the layer most teams underestimate and where most AI projects break after launch.
Stack:
LangChain · LangGraph · FastAPI · Temporal · Composio · pgVector · Pinecone · ChromaDB · OpenAI · Anthropic · Claude · Python · AWS · Supabase · PostgreSQL
Domains:
HealthTech · LegalTech · FinTech · Enterprise SaaS · Workflow Automation
Open to discussing your project happy to review your current setup and suggest the right approach.
