v2.4.1-stable

Autonomous order-tracking and refund processing backend using custom ReAct loops, Zod schema protection, and Groq SDK multi-model fallbacks.

  • Built a custom ReAct orchestration engine (no LangChain) for autonomous order-tracking across multi-step reasoning cycles.
  • Designed a Zod-validated tool registry enforcing schema validation on every LLM output before database writes.
  • Implemented multi-model fallback routing (Llama 3.3-70B to Llama 3.1-8B) via Groq SDK for resilience during outages.
  • Integrated Sentry + Pino structured logging with tiktoken-based cost tracking for full-stack observability.

v1.1.0-beta

AI launch-readiness auditor combining visual intelligence, Lighthouse performance metrics, and static code scans with automated LLM evaluations.

  • Built a 3-tier LLM waterfall (Gemini 2.0 → Groq/Llama Scout → OpenRouter/Claude) with automatic failover.
  • Designed a hybrid scoring engine combining AI audit reviews with deterministic Lighthouse and static metrics.
  • Developed automated screenshot capture for multimodal LLM visual regression reviews.
  • Built static security analyzers scanning for hardcoded secrets, code quality issues, and deployment risks.

v1.0.0-stable

Full-stack telemedicine SaaS platform offering patient triage classifiers, WebRTC consultations, and transaction billing structures.

  • Built a symptom triage classifier to route patients to appropriate specialists based on reported symptoms.
  • Developed WebRTC video consultations via Vonage API — browser-based, no downloads required.
  • Implemented credit system with full audit trail: purchases, deductions, refunds, and transaction history.
  • Built multi-role dashboards (Patients, Doctors, Admins) with automated payout engine and fee calculations.

About & Core Principles

Shubham Bhattacharya

Shubham Bhattacharya

BCA Final Year — Parul University | Vadodara, IN

My engineering philosophy is rooted in architectural minimalism. I believe the best code is code that doesn't need to be written, and the best systems are those that are trivially easy to reason about when things go wrong under high workloads.

I focus primarily on backend API designs, distributed task layers, database performance, and production observability. Currently looking for Backend Developer Internship roles where I can contribute to core server architectures and database layers.
