Architected and shipped the complete digital infrastructure for an early-stage startup as a Freelance Software Engineer.
- 🚀 Zero-to-One Architecture: Built the startup's entire digital presence from scratch. Architected a multi-tenant platform featuring Flutter mobile apps, a Next.js admin dashboard, and a Dockerized Spring Boot backend exposing 340+ production APIs (Dev → Staging → Prod workflow).
- 🤖 AI Infrastructure: Developed a GenAI content engine using automated AI crawlers and a LangChain video generator to create promotional media for service providers. Integrated a Vet AI assistant for symptom-based pet health insights.
- 🔐 Enterprise Security: Implemented a robust auth system using JWT with refresh token rotation, BCrypt-12, JTI revocation blacklisting, RBAC, and secure AWS S3 presigned upload pipelines.
- 📈 Startup Impact: Successfully launched the product to market, bootstrapping 40+ active app users, generating 300+ initial website visitors, improving SEO from 0 to ~700 daily impressions, and orchestrating 50+ automated transactional email workflows.

- ESP32 Shuttle Launcher: Built a closed-loop RPM control system (Embedded C/C++) achieving a 1-second launch cycle. Reduced manufacturing costs by 80%, piloted with All-India ranked players, and generated 50+ pre-orders.
- Offline OTP Generator: Implemented RFC-6238 TOTP authentication, deploying secure offline auth for 200+ users.
Stack: FastAPI • LLMs • Python (asyncio) • gTTS
- Multi-Agent Pipeline: Decomposed unpredictable LLM generation into a strict, 6-stage structured pipeline (Discovery, Culinary Intelligence, Ranking, Clustering, Priority, Routing).
- Multilingual & Audio Intelligence: Engineered a native-script-enforced narration system with concurrent Text-to-Speech (TTS) generation for multi-language travel guides.
- Production-Grade Reliability: Implemented strict JSON schema validation, deterministic scoring outside the LLM, intelligent caching, and parallel async execution to drastically reduce latency.
Stack: FastAPI • React • MongoDB • Twilio • LiveKit • Deepgram
- Engineered a real-time AI voice agent capable of conversational voice calls, automated meeting scheduling, full transcript generation, and a live monitoring dashboard.
