I build the full stack of intelligent systems: the agent harnesses, memory layers, self-correcting loops, and production infrastructure that make AI reliable at scale.

My focus: agentic architectures that plan, execute, and course-correct autonomously. Subagent orchestration. Context engineering for token efficiency. RLHF pipelines that close the feedback loop.

Research in LLM safety, cloud security, and low-resource NLP. Published in IEEE conferences.

Agent Harness & Autonomous Loops

Custom harnesses with tool orchestration, subagent spawning, and self-correcting loops. No human in the loop.

Context Engineering & Memory

Context-compact architectures, RAG pipelines, and persistent memory for coherent multi-turn agents.

RLHF & Eval Pipelines

Human-in-the-loop annotation, automated evaluation, iterative prompt improvement. Data-driven agent quality.

Where I've Built Things
Software Development Engineer 1 Jan 2026 – Present
Nbyula | EdTech Platform, Bangalore
  • Building an RLHF annotation & eval pipeline. Human feedback drives iterative prompt improvement via structured datasets and automated eval runs
  • Built AI document extraction with role-gated access. Parses uploads, autofills structured profile fields
  • Fixed critical production issues: infinite loops, worker starvation, voice AI race conditions
SDE Intern — AI & Full-Stack Dec 2024 – Jan 2026
Nbyula | EdTech Platform, Bangalore
  • Built autonomous messaging agents (Langgraph + WhatsApp Web) that personalize outreach from CRM context. No human in the loop
  • Created a social media conversion agent. Instagram DMs to qualified sign-ups via agentic chatbot flows
  • Engineered a content moderation pipeline: fine-tuned BERT + LLM-as-a-Judge in a self-correcting loop
  • Built an autonomous browser agent (Browser Use + Claude SDK + Langgraph) that fills multi-step forms across external portals
  • Integrated voice AI, real-time transcription with diarization, and tool-augmented search into conversational agents
  • Full-stack: payment flows, CRM dashboards, lead management, Meta Conversion API
  • Taught GMAT quant and verbal via short-form Instagram reels on @gmat_nbyula
SDE Intern — Full-Stack Apr 2024 – Sep 2024
CreditMitra | FinTech, Hyderabad
  • Built the company website end-to-end. MERN, AWS (S3, CloudFront, Route53), role-based access
  • CI/CD with Jenkins + Ansible. Analytics: MS Clarity, GTM, Meta Pixel with server-side events
  • Built an internal HRMS PWA: attendance, payroll, offer letters, employee directory
