Hi, I'm Deepesh 👋

Senior Product Manager building AI + data products that ship, measure, and hold up in production.

6+ years across B2B · B2C · D2C · B2B2C — marketplaces, data platforms, and internal tools. I turn messy, ambiguous problem spaces into crisp product bets with success metrics, then prototype the fastest path to "does this work?" before scaling.

Core focus: agentic AI systems · multi-agent orchestration · marketplace discovery · real-estate intelligence · evidence-grounded LLM systems (with evals) · recommendation engines · geo/data analytics · pricing engines · consumer pain intelligence · SEO/AEO content platforms


🗂️ What You'll Find Here

A mix of:

  • Live products — fully deployed, production-running platforms with real users and real infrastructure
  • Agentic AI systems — multi-agent pipelines, orchestrated workflows, safety governance, and autonomous task execution
  • Production-minded prototypes — projects I'd confidently harden and plug into a real system
  • AI/ML systems — LLM workflows, recommender stacks, applied ML/CV, and evaluation tooling
  • Real estate intelligence — pricing engines, pain point research, geo analytics, and content systems purpose-built for the Indian property market
  • POCs & sandboxes — quick experiments to validate hypotheses before engineering investment

Most repos start from a real product problem — not a tutorial.

⚙️ How I Work

  • Turn vague asks into sharp product problems + success metrics
  • Partner deeply with engineering/design/data (high technical fluency)
  • Prefer evidence over vibes: evaluation, guardrails, measurable outcomes
  • Use AI + automation as leverage — not decoration
  • Ship to production, not just to demos: real infra, real monitoring, real edge cases handled
  • Write to think — documenting architecture, agent contracts, and product bets as I build

🔭 Currently Exploring

Evaluation-first LLM product development — offline test sets, rubric-based scoring, citation coverage checks, refusal thresholds, and regression testing when prompts/models change.

Better retrieval over "more tokens" — chunking strategies, query rewriting, hybrid retrieval (lexical + vector), reranking, and confidence gating.

Evidence-backed "news/intelligence" pipelines — extraction → claim detection → dedupe → timelines → human-readable narratives + auditable artifacts.

Pricing engines with real analytical depth — six-factor data-driven models, scenario-based forward projections, sensitivity analysis, confidence scoring, and no-hardcode design where all parameters are DB-injected at runtime.

Consumer pain intelligence at scale — multi-source scraping, multi-agent LLM pipelines, taxonomy clustering, root-cause hypothesis generation, and human-in-the-loop review queues.

Personalization loops that actually learn — feedback-driven recommenders, session intent inference, segment-driven widgets, and "next best action" logic.

Local-first product engineering — reproducible pipelines, persisted artifacts, Docker-first setup, and clean upgrade paths to production.

Geo + decision intelligence at scale — multi-layer geo rendering, metric overlays, performant choropleths, and config-over-code onboarding for new cities/datasets.

Content systems with control — template-driven generation, SEO/AEO hygiene, structured outputs, strict validation so content is predictable and debuggable, and headless CMS architectures that scale programmatically.

Agentic AI architectures — LangGraph-driven multi-agent pipelines, role-specialised agents, inter-agent communication protocols, safety governance, crisis detection, human oversight loops, and policy-enforced artifact generation at scale.

Trust layers in marketplaces — review intelligence, credibility signals, persona-fit tagging, and deterministic-enough summarization to ship.

First-party analytics and CDP systems — event taxonomy governance, funnel/cohort/segment infrastructure, identity stitching, and DPDP-compliant data platforms built from scratch.
