A production-grade multi-tenant SaaS platform serving Indian businesses with isolated subdomains, custom domain routing, and a 9-step middleware security pipeline with zero-trust tenant isolation.

• 4 independent AES-256-GCM encryption keys with deterministic PII lookups and constant-time auth verification across all flows.
• GST-compliant invoicing with atomic allocation (SELECT FOR UPDATE), credit notes, and webhook-driven payment state machine.
• Full POS terminal with IndexedDB offline queue, barcode scanning, split-tender payments, and live iframe theme studio preview.
• Strict tenant isolation with HMAC-signed proxy signatures, per-host origin allowlist, and Redis-cached domain routing.
• RAG-powered AI advisor (Ray) via Groq LLM with 3-key fallback and 9 parallel real-time analytics queries.

A self-hosted, $0/month autonomous web research and scraping engine built in Go — combining an autonomous ReAct loop, parallel multi-provider discovery (SearXNG, TinyFish, Jina), stealth headless browser automation, DAG-based pedagogical outlines, and SQLite FTS5 local knowledge indexing.

• Multi-provider discovery engine querying SearXNG, TinyFish, and Jina in parallel with URL deduplication, fallback routing, and zero-cost operation.
• Autonomous ReAct agent loop with natural language semantic element locator, automated DOM actions, and schema-driven structured JSON extraction.
• Deep Research Orchestrator decomposing complex queries into sub-questions with parallel worker pools and automated cited markdown reports.
• Stealth browser automation via go-rod with randomized viewports, human-like delays, anti-bot circuit breakers, and Colly fast-path scraping.
• Pedagogical Teacher Agent pipeline with DAG dependency graph execution (Kahn's TopoSort), multi-turn clarification, and 5-dimension critic refinement.

A production-grade business operating system built solo for Indian freelancers — eliminating tool sprawl by unifying client management, GST-compliant invoicing, payment reconciliation, and a passwordless magic-link client portal into a single, zero-config platform.

• 5-tool consolidation with unified client lifecycle — from lead capture to invoice settlement — replacing CRMs, invoice generators, payment trackers, contract managers, and client portals with a single codebase.
• GST-compliant invoicing engine with automatic CGST/SGST/IGST computation, HSN code mapping, e-invoice readiness, and PDF generation with real-time tax summary dashboards.
• Magic-link client portal with token-based passwordless auth, scoped document sharing, live payment status tracking, and branded self-service dashboards — zero credentials required.
• Role-based access control with granular permission scoping, session management via BetterAuth, and Redis-cached session invalidation for instant revocation across devices.
• Email automation pipeline via Brevo transactional API — invoice delivery, payment reminders, overdue alerts, and onboarding sequences with open/click tracking and retry logic.

A high-performance, visible computer-use browser agent written in Rust from scratch — driving real Chromium via CDP with accessibility-first tree perception, a two-agent LLM harness, multi-worker research orchestration, and a 6-layer resilience engine built for $0 infrastructure cost.

• Accessibility-first perception using Accessibility.getFullAXTree and structural diffing with stable @eX refs — slashing token footprint by 70%+ vs full-page screenshots.
• Two-agent LLM harness (intent-routing ChatAgent + ReAct-loop BrowserAgent) connected via typed Handoff and Result contracts with deterministic pre-flight DAG planning.
• Multi-worker research orchestration fanning out across platforms concurrently via Tokio JoinSet with isolated CDP browser contexts and per-domain concurrency caps.
• 6-layer resilience engine auto-recovering from stale refs, cookie/modal interrupts, mid-task session loss, Cloudflare 429 backoff, and irreversible action pause gates.
• Native Tauri 2 desktop shell with high-throughput Channel<any> streaming live partial findings, step progress lines, and 4K downscaled screencast frames.

MediLife is an AI-powered hospital intelligence platform that matches patients with the right hospital based on symptoms, severity, distance, and live bed availability. Users chat with an AI assistant (supporting Hindi, Hinglish, and English), get triaged, and book a bed directly — with a one-tap Emergency SOS for critical situations. The platform also includes a Digital Health Profile (blood group, allergies, medications) that's auto-shared with hospitals during emergencies to save critical time. A dedicated hospital dashboard/admin panel for real-time bed management and AI-based patient routing.

• Architected for resilience
• High-volume data streaming

VisuoSlayer is an interactive platform that teaches DSA through real-time visual animations — students write code and watch the logic execute step-by-step visually at runtime. It also covers core programming fundamentals, making it useful for beginners and interview prep. Built with Canvas API for smooth, high-performance rendering of complex algorithms.
