Sirwagya Shekhar — Full Stack & AI Developer

Product Engineer • Open to new work • Pune, India

I build software that feels alive. Intelligent products, distributed backend infrastructure, and polished digital experiences.

About Me

Full-stack and AI developer working where high-reliability engineering meets thoughtful product design. I care about the complete system loop: model inference latency, robust event outboxes, fault-tolerant media pipelines, and sub-frame interface response.

  • AI Systems & Media Pipelines: Multimodal AI, computer vision scoring, video frame processing, and streaming LLM inference architectures.
  • Distributed Backend Architecture: High-concurrency APIs in Rust (Axum) and Python (FastAPI), asynchronous RabbitMQ queues, Redis state engines, and PostgreSQL.
  • Frontend Craft & Motion Engineering: User interfaces powered by React, TypeScript, and hardware-accelerated GSAP motion systems.
  • System Integrity & Invariants: Auditable systems with SHA-256 tamper-evident ledgers, Primavera P6 XML exports, and fault-tolerant pipeline checkpointing.

Selected Work & Case Studies

Nexora AI — Construction Site Intelligence

Category: AI Systems • Distributed Architecture • Computer Vision

Overview: Turning fragmented construction evidence into auditable project intelligence. EPC construction projects suffer from fragmented field reports, spreadsheets, photos, and voice memos. NEXORA AI normalizes messy site observations, matches them to activity schedules using hybrid AI, and provides an auditable trust-plane with Oracle Primavera P6 export capabilities.

Key Capabilities: FastAPI multi-modal AI ingestion, hybrid matching engine (RapidFuzz lexical scoring + sentence-transformer embeddings), Rust Axum trust-plane enforcing schema-compliant Oracle Primavera P6 XML exports & SHA-256 audit logs, RabbitMQ asynchronous job dispatch with Redis caching, PostgreSQL persistence, and Supabase object storage.

Technologies: Rust (Axum), FastAPI, React 19, PostgreSQL, RabbitMQ, Redis, Supabase, RapidFuzz, Sentence-Transformers, Primavera P6 XML.

OnceUponMe Video Engine — Cinematic Reel Automation

Category: AI Pipelines • Media Engineering

Overview: An automated, production-ready video engineering pipeline that converts full-length movies into personalized, cinematic children's reels. Operates with zero generative video hallucination — all visual frames are deterministically extracted, scored, and orchestrated from real movie footage.

Key Capabilities: Video understanding & automated scene boundary analysis, deterministic segment selection and OpenCV visual scoring algorithms, Gemini AI narrative scripting, ElevenLabs voice synthesis with precise timing, FFmpeg clip extraction, and Remotion (Node.js) for programmatic 60fps reel rendering with MongoDB checkpointing.

Technologies: Python, OpenCV, FFmpeg, Remotion, Node.js, Gemini AI, ElevenLabs, MongoDB.
