Hardyal Singh Deora

Software architect with 15 years in backend and platform engineering, now designing and running LLM agent systems in production: tool use through Model Context Protocol (MCP), unattended scheduled agents, and guardrails and cost control for AI coding agents.

Brings the platform discipline agents need to be trusted: service boundaries, idempotency, audit trails, rollback plans and specifications other engineers build from.

Owns the architecture of a 13-microservice commercial platform on Amazon Web Services (AWS) with TypeScript, Python and PostgreSQL, and leads a squad while guiding about 10 engineers.

Core Skills

Agentic AI: LLM agents, tool use / function calling, Model Context Protocol (MCP) servers and clients (stdio, Streamable HTTP), scheduled agent orchestration, human-in-the-loop review, guardrails, token and cost control, AI-assisted development (Claude Code)

LLM engineering: Retrieval-augmented generation (BM25 + Gemini embeddings, reciprocal rank fusion, cited sources), retrieval evaluation (hit@1 / hit@5 in CI), JSON-schema structured output (Zod, Gemini responseSchema), multi-provider integration (Anthropic Claude SDK, Google Gemini, local models via Ollama), context budgeting, image generation (Gemini image models)

Real-time AI (contributed): Voice agents on LiveKit/WebRTC, OpenAI and Gemini realtime models, speech-to-text build-vs-buy evaluation (managed APIs vs self-hosted Whisper)

Architecture: System and solution architecture, microservices, event-driven architecture, API gateway (JWT, rate limiting), backend-for-frontend, ports and adapters, idempotency, architecture decision records, build-vs-buy evaluation

Languages & Frameworks: TypeScript, Python, Node.js (Express, Hono), JavaScript, SQL, React, Angular, PHP (Laravel)

Data & Cloud: PostgreSQL, MySQL, Redis, MongoDB, Elasticsearch, ClickHouse, zero-downtime migration; AWS (S3, SQS, RDS, CloudFront), Azure, Docker, CI/CD

Leadership: Technical roadmaps, phased delivery, risk and rollback planning, stakeholder communication, mentoring senior engineers, Agile (SAFe, Scrum)

Professional Experience

Principal Software Engineer

Educational Initiatives — Ahmedabad, India

07/2024 – Present

Built and run an unattended LLM agent pipeline (TypeScript, Node.js) that reviews open pull requests every 30 minutes, calls tools through Model Context Protocol (MCP) and publishes a triaged report per repository.
Built claude-toolkit, ten dependency-free CLI tools that add guardrails and cut token cost for Claude Code agent sessions.
Contributed to a LiveKit/WebRTC voice-agent pipeline (OpenAI and Gemini realtime models, per-session transcription, lifecycle webhooks) and its speech-to-text build-vs-buy decision, costing managed APIs against self-hosted Whisper under data-protection constraints.
Own end-to-end architecture for a B2B commercial platform of 13 microservices behind one API gateway: service boundaries, data models, contract-first integrations, JWT authentication and rate limiting at the edge.
Directed a MySQL to PostgreSQL migration across 6 product lines designed to run with no maintenance window (about 30 tables consolidated into 4; partly live, the remaining product lines in pilot), with idempotency, retries, monitoring and rollback specified in a ~25,000-word document other engineers executed.
Moving a live adaptive-learning product from PHP to Node.js feature by feature (2026), with AI coding agents writing the code to team-written guidelines and every change reviewed by engineers.
Translated sales and finance requirements into a finance-auditable discount engine with a four-tier approval ladder, and payment mapping that cut reconciliation lag.
Lead a squad of 4 engineers and guide about 10 across teams; set review, testing and coding standards and coach engineers on system design.

Lead Software Engineer

Educational Initiatives — Ahmedabad, India

04/2020 – 07/2024

Designed and led a strangler migration of a live PHP/MySQL application to Node.js microservices on PostgreSQL with an Angular UI: 70 pages across 12 modules in 3 months with 2 developers, using a shared PHP-session + JWT login and per-module MySQL write flags so every product on the shared database kept working; no user-visible interruption, legacy app retired.
Designed the order and subscription data model the platform still runs on, and a per-product order-creation REST API with OpenAPI (Swagger) documentation.
Led sprint planning, backlog grooming and stakeholder communication across about 30 recorded sprints; grew the team from 2 full-time and 2 contract engineers with 30- and 90-day onboarding plans.
Upgraded a live product from PHP 5.2 to PHP 8.2 and retired the old servers (2023), recognised with the company's “Mountain Mover” award; reworked CI/CD on Bitbucket Pipelines and shipped a versioned partner CRM integration (API v2).

Senior Software Engineer

Educational Initiatives — Ahmedabad, India

06/2016 – 04/2020

Built sales-funnel and reporting dashboards, an internal tax module that removed manual finance steps, and diagnostic tooling for regional-language (Hindi) proficiency assessment.

Earlier roles

Analytics Solution, Ilogix Infotech, Seven Sleek, Softyoug Solution — Ahmedabad and Vapi, India

10/2011 – 06/2016

Senior PHP Developer, PHP Developer and Front End Developer: Laravel and CodeIgniter platforms, REST APIs for mobile clients, and SEO-optimised web front ends.
