EXPERIENCE
WHO IS DANISH?
Danish Khan is a Full-Stack MERN Developer and SaaS Product Engineer based in India with 3+ years of professional engineering experience. He specializes in bridging the gap between complex backend architectures (databases, APIs, aggregations) and fluid, high-converting modern user interfaces.
Takes features from whiteboard database schema design all the way to responsive UI, automated testing, and cloud deployment.
Defensive coder who anticipates race conditions, rate limiting, network drops, and database index overhead from day one.
Requires minimal oversight. Clarifies ambiguity upfront, gives concise async updates, and respects sprint deadlines.
WHAT DOES HE BUILD?
Danish engineers scalable software products that eliminate operational friction and handle real transaction volume:
Logistics & Courier SaaS
AiShyp, SureShip, 4Murti, AnteairMulti-carrier rate engines comparing courier APIs in real-time, automated manifest generation, Airway Bill (AWB) creation, and door-to-door tracking.
Data Visualization & BI
Vizta & VizLabsNo-code drag-and-drop tool that ingests raw CSV, Excel files, and live database streams into dynamic interactive charts, cohort tables, and executive digests.
Multi-Tenant Cloud Platforms
Zero Data-Leakage ArchitecturesMulti-organization architectures with partitioned database schemas, custom domain routing, role-based access control (RBAC), and subscription billing tiers.
High-Throughput APIs & Feeds
Redis, WebSockets, WebhooksAsynchronous RESTful APIs with Redis in-memory caching layers, Socket.io bidirectional live updates, payment gateway listeners, and third-party webhooks.

REAL-WORLD EXPERIENCE
Chronological production milestones demonstrating real technical responsibility, architectural decisions, and quantifiable business outcomes:
Lead Full-Stack & SaaS Systems Architect
Situation & Task: Ecommerce sellers were losing hours manually comparing carrier shipping rates across individual courier websites, leading to delivery delays and dispatch errors.
Action: Designed and deployed a unified rate engine in Next.js and Node.js that fires parallel queries across multiple carrier APIs, normalizes disparate JSON payloads, calculates volumetric weights, and surfaces the best-fit courier in under 400ms.
Measurable Results:
- Reduced merchant dispatch turnaround time by 45% via automated batch manifest generation.
- Integrated real-time webhook listeners to broadcast live tracking status updates without client polling.
- Engineered multi-tenant isolation guaranteeing zero cross-talk between competing merchant stores.
Product Engineer & BI Dashboard Architect
Situation & Task: Non-technical business users struggled to extract actionable insights from dense Excel/CSV data exports containing hundreds of thousands of rows.
Action: Engineered a browser-optimized streaming parser and MongoDB aggregation pipeline capable of ingesting raw spreadsheet datasets and generating interactive, draggable BI widgets, cohort heatmaps, and customizable charts.
Measurable Results:
- Processed 500K+ daily analytics events with sub-second MongoDB query latencies.
- Built 1-click executive PDF report generation directly in the browser with zero server CPU bottleneck.
- Enabled instant column filtering, multi-field aggregations, and visual chart exports.
Freight Logistics Systems Developer
Situation & Task: National freight and express air cargo operations suffered from fragmented regional branch communication and manual airway bill (AWB) paperwork.
Action: Architected a centralized consignment tracking portal linking PAN India branches, automating AWB number generation, calculating airline volumetric formulas, and tracking vehicle fleet statuses.
Measurable Results:
- Achieved real-time synchronization across multi-state hub terminals with zero consignment misplacements.
- Automated 100% of air freight manifest documents, speeding up tarmac handovers.
WHAT VALUE CAN HE BRING TO A COMPANY?
What engineering leaders and product teams gain on Day 1 by bringing Danish into the organization:
Zero Handoff Friction
Full-stack autonomy means features move from whiteboard concept to production deployment without the overhead of waiting for separate backend and frontend handoffs.
Production Reliability
Writes defensive, battle-tested code with error boundaries, rate limiting, retry mechanisms, and database index tuning built-in.
Business-First Mindset
Understands customer retention, checkout conversion, and operational bottlenecks. Focuses engineering effort on what directly impacts revenue.
Aesthetic UI Polish
Bridges engineering with design. Delivers smooth micro-interactions, responsive layouts, and modern Canva-grade styling that elevates brand credibility.
High Autonomy
Requires minimal supervision. Capable of taking vague product specifications, clarifying edge cases, and executing independently.
Modern Stack Agility
Quick to adopt Next.js 16, React 19, Tailwind v4, Redis caching, or AI-assisted APIs to keep your engineering stack cutting-edge.
