Recruiters & HR

Hiring a senior or lead engineer?

I'm actively looking for senior, lead, or full-stack roles — full-time, contract, or remote — where I own products end to end and lead the people shipping them. I reply to every message within 24 hours.

Founders & Teams

Need to build something real?

I can help with APIs, internal tools, automation, crawlers, search, queues, AI workflows, and legacy modernization.

Stack Flexible

Your stack is not a blocker.

Laravel, PHP, Python, Node, cloud, data, or a new stack: I learn what the business needs and ship.

About

Backend systems, AI workflows, and business-first execution.

I care about clean services, measurable outcomes, and systems that hold up under scale.

I specialize in modernizing legacy systems, simplifying backend architecture, and building automations that remove repeated manual work.

I bring an architecture-first mindset, but I stay practical: understand the business goal, learn the stack, then ship the simplest reliable path.

If your team needs Laravel, Python, Node, cloud, search, APIs, data pipelines, or AI workflows, I can adapt quickly and build with ownership.

Two companies, six products, and a path from building features to leading the pod that ships them.

Founder

Ottcinematv — my own product

2025 — Present

Founded, built, and run an OTT discovery platform solo — product decisions, architecture, AI-powered content pipeline, servers, and growth.

Laravel TMDB API Gemini AI Redis MySQL Hostinger GA4 Search Console

- Built the entire platform end to end: TMDB API ingestion, intelligent metadata crawling, and Gemini AI enrichment on a Redis job queue.

- Run my own Hostinger servers — I deploy and maintain ottcinematv.com and tarunrana.in myself, and handle uptime, config, and cost.

- Analyse traffic and user behaviour through GA4, and manage page indexing, crawl errors, and search issues in Google Search Console.

- Own every layer — roadmap, backend, infrastructure, and SEO — with no team to delegate to.

Team Lead — Senior Software Engineer

91mobiles, Gurugram, Haryana

Jul '22 — Present

Leading end-to-end delivery for two of India's highest-traffic consumer tech platforms — 91mobiles.com and mysmartprice.com — from architecture and development through staging QA, CI/CD, and AWS production release.

Laravel PHP 8.3 Python Elasticsearch Redis MySQL AWS Docker CI/CD AI Automation

- Lead a cross-functional pod (QA engineer + UI developer), running the full delivery cycle: development → staging QA sign-off → CI/CD pipeline → production deployment on AWS.

- Consolidated a fragmented 5-repository legacy architecture into 3 and drove a PHP 5 → 8.3 and Laravel 6 → 12 upgrade solo within a 30-day window.

- Delivered brand campaign integrations for Samsung, Intel, MediaTek, and Dell across high-traffic product and comparison pages.

- Built internal backend dashboards used daily by content, catalogue, and campaign teams to manage products and specifications at scale.

- Integrated AI scripts into backend workflows — automating spec correction and catalogue data quality that previously needed manual review.

- Own search relevance and performance with Elasticsearch and Redis caching across high-traffic pages.

Software Engineer

Bytesview Analytics, Noida

Jan '21 — Jul '22

Built four SaaS analytics products end to end at a fast-moving startup — frontend, third-party API integrations, billing, and the data layer underneath them.

Laravel PHP React Chart.js Elasticsearch MySQL Stripe Twitter API v2 SCSS

- Migrated 150M+ Twitter user records from MySQL to Elasticsearch — a platform-wide search performance win and the company's single biggest infrastructure improvement of the year.

- Built newsdata.io from scratch: frontend, News API integration, Stripe billing, and a React + DataTables search dashboard for keyword-based news discovery across multiple data sets.

- Created followersearch.com's analytics dashboard — follower, following, and engagement insights visualised with Chart.js on top of the Twitter API.

- Led trackmyhashtag.com's Twitter API v1 → v2 migration, a breaking platform-wide change, and shipped Stripe subscription billing alongside it.

- Applied lazy loading, Core Web Vitals, and SEO optimisation across product frontends.

- Developed bytesview.com's frontend with SCSS, Blade, and semantic HTML.
