AUTHOR //KESHAV SANDHU//PRODUCT ENGINEER & BUILDER

I build resilient software across product, interface, and systems.

I take products from specification to operation, connecting interface decisions with the data, APIs, and workflows behind them. Recent systems support 50+ organizations, 100K+ records, and AI workflows that cut manual effort by ~60%.

01 // INTERFACE

Product & Interaction

High-craft user interfaces, design systems, responsive layouts, and WCAG accessibility standards.

React · Next.js · TypeScript · CSS Architecture
02 // BACKEND

Systems & Multi-Tenancy

Granular RBAC governance, tenant isolation, quotation-to-invoice workflows, and clean REST APIs.

Node.js · Express · Prisma · PostgreSQL · Redis
03 // AI INTEGRATION

Applied AI & RAG

Contextual document querying, vector embeddings, LangChain services, and model switching pipelines.

LangChain · Gemini · Vector DBs · Retrieval-Augmented Gen
04 // PERFORMANCE

Optimization & Scale

Query refactoring, Redis caching layers, ~40% latency reduction, and predictable cloud deployments.

SQL Indexing · Docker · AWS (EC2/S3/CloudFront) · CI/CD

ENGINEERING RANGE / FIELD NOTES

Systems, not just screens.

From contextual AI to tenant isolation and the performance work between them.

Engineering capabilities include genai & autonomous agents, vector embeddings (rag), high-throughput system architecture, next.js app router & rsc, distributed redis caching, multi-tenant saas platforms, sub-100ms optimistic ui, pgvector & semantic search, langchain services & guardrails, p99 latency audits & indexing, zero-downtime ci/cd deployments, real-time telemetry & observability, document conversation engines, role-based access control (rbac).

+ENGINEERING LAB // PRACTICE AREAS

Useful systems, examined at the seams.

The practice combines product interface work with the systems behind it - where context, permissions, performance, and operational workflows need to hold up.

01 // AI & CONTEXT

Document-aware conversations

Conversational interfaces, contextual PDF responses, LangChain services, and vector-backed retrieval shaped through Twin Protocol work.

02 // OPERATIONS

Multi-tenant systems

Tenant isolation, RBAC, configuration workflows, and operational dashboards developed across compliance and retailer administration platforms.

03 // PERFORMANCE

Clearer paths under load

Query refactoring, caching, indexing, and API optimization applied where responsiveness depends on the whole system rather than a single screen.

+SELECT ENGAGEMENTS

Have a product or system that needs a clearer path forward?

I work across product interfaces, backend systems, and applied AI - from the first useful version through the operational details that make it dependable.
