hey, i'm Darshan.

in march 2026 anthropic shipped a 1 million token window at standard pricing and inference costs collapsed 240x in 18 months. compute is cheap. context is expensive. here's the discipline that actually separates production agents from demos in 2026.

a public benchmark ran a 6-task crm agent flow 10 times and hit 25% end-to-end success. meanwhile 57% of orgs claim agents in production. that gap is the most important engineering problem in 2026. here's how i design for the reliability we actually measure.

stewardship is the engineering virtue nobody budgets for. but the thing that actually outlasts you isn't the code, it's the constraints, the names, the data model, and the 'why' doc. and the best act of stewardship is usually deletion.

ai executive assistant platform

a production-grade SaaS platform that replaces human executive assistants with per-user ai agents. Go backend orchestrating agentic workflows: 13-stage email processing (categorize, summarize, RAG-backed drafting), multi-model LLM routing with circuit-breaker fallback, and goroutine supervision with backoff recovery. 107-component Next.js frontend with 27 routes, 5 Zustand stores, real-time Supabase WebSocket subscriptions, 60 SQL migrations with compile-time RLS, AES-256-GCM encryption with key rotation, 4-tier Stripe billing ($97 to $697/mo), and 16 scheduled cron jobs for nightly batch processing.

ai research collaboration discovery

ai-powered platform for UT Arlington's MAE department that matches researchers using semantic vector search. FastAPI backend converts natural language queries into 384-dim embeddings, searches faculty profiles via pgvector, queries OpenAlex/arXiv/NSF in parallel, and uses LLMs to explain match rationale, all streamed via SSE. Next.js 16 frontend with Supabase auth and Playwright E2E tests.

intelligent email automation

email automation platform with real-time streaming architecture. Go backend runs async job workers for email fetching, ai processing, and sending, with a cron scheduler for periodic IMAP sync and digest delivery. SSE broker pushes live pipeline status to the Next.js frontend. dual api pattern: server-side REST proxy for mutations, client-side SSE for real-time updates.

cross-platform fitness app

a fitness and wellness consumer application built as a cross-platform experience that runs as a web app, native iOS app, and native Android app from a single codebase using Capacitor. features geolocation-based gym discovery, Supabase authentication, and a polished mobile-first UI with shadcn/ui components.

digital library ecosystem

a two-app ecosystem: a curated reader with 49+ book summaries distilled into actionable insights, and an auth-protected admin dashboard for content management. features SSG with ISR and webhook-based cache invalidation between apps, Supabase RLS with defense-in-depth auth, and a shared design token system. gold-on-black aesthetic with six-category filtering.

business payment ecosystem

a multi-service business platform spanning payment processing, partner management, and consumer experiences. secure Node.js Express API handles single/bulk payment records, partner balances and payouts with automatic notifications, dynamic revenue sharing, and JWT + time-based passcode authentication. includes a partner analytics portal with Recharts dashboards and a full CI/CD pipeline with multi-Node version testing and preview/production deployments.

Turborepo multi-app platform

a monorepo business platform built with Turborepo, housing two applications (a consumer-facing web storefront and an internal CRM dashboard) sharing packages and build infrastructure. Turborepo orchestrates parallel builds, shared linting, and workspace-level dependency management across both apps.

ai time management dashboard

a productivity dashboard with ai-powered time analytics. Next.js 16 frontend with interactive Recharts visualizations and markdown-rendered ai summaries. Go/Gin backend with JWT authentication, WebSocket real-time updates, PostgreSQL via pgx, and email notifications via gomail.

healthcare platform

a healthcare and wellness service platform with a React frontend and Express/MongoDB backend. features JWT authentication, CSV data import, file uploads via Multer, and Joi input validation. designed for accessible health information and service discovery.
