How I lead & build

Technical Strategy & Architecture

Own architecture end-to-end — multi-cloud platforms, build-vs-buy calls, and roadmaps that survive scale. 5x AWS-certified; designed multi-tenant SaaS and AI platforms from a blank page to production.

Engineering Leadership

Build and lead teams that ship. Ran a 30-engineer org as Executive Director, and have been architect & delivery lead on enterprise client platforms — hiring, mentoring, and owning the outcome.

Agentic AI Strategy & Delivery

Set AI direction and deliver it — autonomous agents (PDCA, ReAct, MCP), LLM products, and fine-tuning platforms taken from thesis to production, not slideware.

Platform & DevOps Foundations

The operational core: IaC (Terraform/CDK), CI/CD, multi-region and multi-tenant provisioning, observability and automated rollback — the guardrails that let teams move fast safely.

Security & Compliance Programs

Stand up security posture, not point fixes — autonomous offensive-security, SASE/VPN, identity (Auth0), and compliance mapping from Check Point to cloud.

0→1 Product & Founding Engineering

Take products from idea to live and operate them. Founder/lead on multiple platforms — fintech marketplaces, AI tooling, security training — full-stack across React, Node, and Python.

AgentOne — SAP B1 AI Automation Platform

A multi-tenant SaaS platform (sapb1.ai) that connects on-prem SAP Business One to cloud AI agents. A Go headless agent bridges the customer's SAP B1 (HANA / SQL Server) to a broker and connectors; a Python configurator self-provisions each tenant on GCP Cloud Run — Cloud SQL, buckets, schema bootstrap, and a per-tenant MCP server. ~22 microservices span an agent registry, downloadable connectors, Stripe billing, and MS Teams / WhatsApp integrations.

AI-Native Hiring Funnel

The screening pipeline you're using right now. A single profile.json is the source of truth for this Gatsby site, an MCP server (8 tools incl. a semantic match_role engine), Schema.org + llms.txt + .well-known discovery, and a live serverless link-minter: paste a JD into a password-protected admin UI and get a short s.nishanttiwari.com link that returns a self-contained screening prompt — content-negotiated to serve a copy-and-paste page to browsers and raw text to AIs. No LLM in the request path, so it runs at ~$0. Surface propagation is regression-tracked in a custom agentic QA system (AQA).

nishant-profile-mcp — AI-Readable Résumé MCP Server

An MCP (Model Context Protocol) server that exposes my professional profile — skills, projects, certifications, and experience — directly to AI recruitment agents. Ships a local-embedding semantic matcher and a 5-dimension match_role engine that scores any job description against my profile and returns a hire signal. 8 tools over stdio, fully offline (runs MiniLM embeddings locally, no API key).

Yukt Capital — Invoice-Discounting Marketplace + MCP Server

Yukt Capital (yuktcapital.com) is a TReDS-style invoice-discounting marketplace where suppliers raise invoices on corporate buyers and investors finance them early at a fair discount. I built a companion MCP server (17 tools) that lets any MCP host — Claude Desktop, Claude Code, Gemini CLI — log in and run the full workflow in natural language: browse the marketplace, fund or bid on invoices, raise invoices, run reverse-factoring programs, and trade on the secondary market.

AQA — System of Record for Agentic Verification

A TestLink-style test-management and verification-memory platform built for the agentic coding loop, exposed over MCP (43 tools). It tracks plans, cases, dependencies, run history, and requirements-to-test traceability, with a claim/verify protocol (doer ≠ checker) and semantic regression memory: a failed run's root-cause reasoning is stored and recalled when a similar failure recurs, so agents get the prior diagnosis instead of re-deriving it. One service layer, surfaced three ways — REST API, MCP server, and CLI.

l33tpwn — Cloud Pentest Training Platform (2025 Overhaul)

A ground-up rebuild of l33tPWN into a hosted, browser-based cybersecurity training platform (l33tpwn.com), in the style of HackTheBox / TryHackMe. Each student gets a private AWS lab — a Kali attack box, an optional Kali Purple blue-team/SOC box (Suricata IPS + Wazuh), and on-demand vulnerable target VMs from a 48-target catalog — all running in the browser via noVNC in ~90s. Added a leet/l33tpwn CLI (~30 verbs across student and operator faces), keyless shell access via AWS SSM Session Manager, guided walkthroughs, and EventBridge-driven idle teardown.

OpenClaw AI — Dream Server Open Source Contribution

Contributed to Dream Server, an open source self-hosted AI platform ('the Linux of Local AI'). Implemented OpenClaw-to-Open-WebUI integration: built HTTP API shim, LLM provider patching (OLLAMA_URL/LITELLM_KEY), Docker Compose overlay for service orchestration, and configuration layer for connecting OpenClaw's agent framework to Open WebUI's chat interface. PR accepted and personally integrated by the project maintainer into the Lemonade release branch.

Autonomous AI Sales Pipeline — SAP B1 Lead Generation

Built a fully autonomous multi-agent AI sales pipeline using OpenClaw on GCP. 6-agent team: Scout (lead scraping from partner case studies), Qualifier (composite scoring with identity/event/contact dimensions), Verifier (SAP B1 confirmation), Enricher (contact discovery via Apollo/Hunter/theHarvester/Perplexica cascade), Signal Hunter 'Pulse' (intent-based scoring using Gemini/Groq for hiring/funding/complaint/migration signals), and Closer (email generation). Custom pipeline database with SQLite, real-time dashboard on port 3000, WhatsApp gateway integration, automated signal sweeps on cron. Built from scratch in 3 weeks.

Check Point Cloud Firewall Manager

Built a comprehensive cloud firewall management platform bridging Check Point and AWS. Created a custom SDK surpassing Check Point's own, enabling programmatic rule management across Security Groups, NACLs, Network Firewall (stateless and stateful/Suricata), and Web ACLs. Automated network feed ingestion into AWS prefix lists. Built pipeline to pull rules from Check Point, translate to intermediate format, and deploy to AWS Network Firewall with named rules and variable mapping. Deployed on GCP CloudRun with automated triggers. Set up Headscale/Tailscale VPN mesh across AWS regions for secure connectivity. 638+ hours of development.

Product Customizer - ColdFusion to FOSS Migration

Infrastructure rescue migrating a product customizer platform from end-of-life Adobe ColdFusion + MSSQL stack to a fully FOSS stack before ColdFusion's core support ended (Nov 2025). Migrated the application server from ColdFusion to Lucee, database from MSSQL to MySQL, containerized with Docker, and deployed on GCP. Preserved the product customizer's backend logic, ontology system, and WooCommerce integration throughout the migration.

LLM Email Interface

Built an email-based interface for LLM interaction using AWS SES for email receiving, OpenAI Assistants API for conversation management, DynamoDB for state, and S3 for attachment storage. Implemented CloudWatch logging, CloudConvert for file processing, thread management for multi-turn conversations, and an AWS Amplify frontend with social login and custom prompt templates. 572 hours of development, $34,340 project value.

CodelessGPT - AI Workflow Platform

Built a no-code AI workflow automation platform (codelessgpt.com). Users upload documents into a Library and Datasource system, compose reusable Prompt Templates, and wire together Actions (Gmail, API calls, web crawling, search) into automated Flows. The platform runs GPT-powered analysis pipelines over uploaded knowledge bases — e.g. resume screening against job descriptions, portfolio analysis, blood report analysis, pentest report review. Essentially a RAG-based workflow orchestration engine where non-technical users build and run AI-powered document processing pipelines without writing code.
