Hi, I'm Divyang Panchasara 👋

Solution Architect | AI/ML & GenAI Engineer | Cloud Architect | Systems & Semiconductor R&D

I have 20+ years of experience designing scalable enterprise and cloud-native systems across AWS, Azure, and GCP. My current focus is on building AI-native platforms, custom LLM/Transformer architectures, agentic workflows, cloud modernization, and applied AI for enterprise domains such as retail, manufacturing, automotive, and document intelligence.

I like working at the boundary of software architecture, AI research, systems engineering, and semiconductor innovation.


🚀 What I'm Building / Exploring

🧠 AI, ML & Generative AI

  • Custom Transformer and LLM architecture experiments focused on lower memory movement, smaller parameter count, and efficient inference.
  • Agentic AI and multi-agent workflow design for software engineering, architecture generation, document processing, and enterprise automation.
  • LLM-powered extraction, mapping, and structured JSON generation for enterprise document automation.
  • Multi-agent solution patterns using planner agents, researcher agents, coding agents, reviewer agents, retrieval agents, critic/evaluator agents, and workflow orchestration.
  • Advanced Reinforcement Learning concepts for autonomous decision-making, optimization, planning, reward modeling, and adaptive AI systems.
  • Custom Transformer and LLM architecture experiments focused on lower memory movement, smaller parameter count, and efficient inference.
  • LLM-powered extraction, mapping, and structured JSON generation for enterprise document automation.
  • Exploring OS, semiconductor, and accelerator ideas for future AI systems.
  • Applied ML using PyTorch, Scikit-learn, Hugging Face, Ollama, AWS Bedrock, Azure OpenAI, and Vertex AI.
  • Creating cloud-native architectures that are secure, scalable, and cost-aware

☁️ Cloud & Enterprise Architecture

  • Multi-cloud solution architecture across AWS, Azure, and GCP.
  • Serverless, ECS/Fargate, Lambda, API gateways, event-driven systems, DynamoDB, Firestore, BigQuery, and cloud-native integrations.
  • Retail loyalty, campaign, voucher, customer savings, and large-scale transactional data systems.

🧩 Systems & OS Research

  • Exploring custom operating-system architecture, per-core scheduling, capability-based security, syscall gates, memory protection, and multi-architecture boot flows.

🧬 Semiconductor / VLSI / Accelerators

  • Exploring custom ISA, AI accelerators, RISC-V/Shakti ecosystem, simulation, verification, and PDK-backed chip IP.
  • Research interest in efficient compute architectures for LLMs and AI workloads.

🧪 Materials AI / Semiconductor R&D

  • ML-assisted inverse design for silicon-based block copolymer self-assembly and lithography-oriented materials discovery.

🧠 Custom Transformer & Efficient AI Architecture

I am exploring alternatives and improvements to standard Transformer architectures with a focus on:

  • Reducing parameter count without losing reasoning quality.
  • Lowering data movement between memory and compute.
  • Improving context handling using memory banks, gating, compression, and structured retrieval.
  • Designing architectures that are practical for small GPUs and edge/low-resource environments.
  • Studying mathematical alternatives to attention-heavy computation for LLMs, image generation, and video generation.
