Senior Software Engineer
building fast, scalable
production systems.

Hi, I'm Muhammad Ali Ansari. I build and scale backend systems with Node.js, Python, PostgreSQL, and GCP, and ship the React and Vue frontends to match. I love digging into complex problems: performance, databases, security, and reliability at production scale.

Node.js, Python, PostgreSQL & GCP specialist with 5+ Years of experience, plus Vue & React on the frontend.

I'm a Senior Software Engineer who loves solving complex backend problems: scalable APIs, database architecture, and performance at production scale. I work with Node.js, Python, PostgreSQL, and GCP, and modern frontends in React and Vue, delivering clean, high-performance, SEO-friendly applications end to end. I've helped startups grow traffic, cut cloud costs, and launch products from the ground up. Happiest in the backend, but glad to own frontend work whenever a role needs it.

At Awards Box (Berlin), I lead engineering for the platform end to end with Node.js, Python, Nuxt.js, PostgreSQL, OpenAI, and Google Cloud Platform. I led a team of 4 engineers to the first public launch on web and mobile, and grew the product to 9,000+ organic users with zero ad spend. Along the way I cut page load times by 56%, blocked 600K+ scraper requests during a bot-scraping campaign, and lowered infrastructure costs by ~$500/month (~$6K/year).

I'm passionate about building fast, reliable systems that deliver measurable results. My strengths include performance optimization, database and API design, and SEO-driven development, with modern frameworks like Vue, React, and Next.js for long-term scalability. I back that work with automated testing (unit, integration against real datastores, and cross-browser end-to-end), wired into gated CI/CD so nothing broken ships. Lately I've gone deeper on infrastructure: containerizing services with Docker, deploying them on AWS ECS Fargate, and provisioning the whole cloud topology as Terraform infrastructure as code.

How I work

I use AI (Claude Code) as a daily development assistant that handles boilerplate and the repetitive grind, while I own every engineering decision: architecture, tradeoffs, code review, and final testing before anything ships. Faster delivery, same quality bar, backed by three Anthropic certifications.

Where I've worked

Senior Software Engineer

Awards BoxBerlin, Germany (Remote)
Sep 2023 - Presentawardsbox.com ↗
  • Led a cross-functional team of 4 engineers (mobile, frontend, backend, full-stack) in a fully remote environment through the first public launch of the website and mobile app, then grew awardsbox.com to 9,000+ organic users with zero ad spend.
  • Owned production defense against an adaptive bot-scraping campaign (16 bot families, residential proxies, headless browsers): rebuilt the CDN firewall around browser-fingerprint checks, blocking 600K+ disguised-bot requests in 25 days and cutting unverified server-side renders by 94%, while search-engine crawlers kept full access.
  • Diagnosed and fixed Nuxt SSR memory leaks via heap profiling, reducing memory usage from 90%+ to ~25-30% and CPU usage from 90%+ to ~20%, ending runaway auto-scaling and lowering Cloud Run costs by ~80% (~$500/month).
  • Engineered a custom PostgreSQL full-text & faceted search engine (55,000+ items, 8+ filters) with GIN indexing and 100-200ms response times, saving an estimated $5K-$10K annually versus tools like Algolia/Elasticsearch.
  • Cut API response times by 75% under high concurrency with a Redis caching strategy and PostgreSQL connection pooling.
  • Architected the platform's async, multi-worker Python (Sanic) backend and moved it off serverless Firebase: migrated 9 production Firestore tables to PostgreSQL and built an ETL pipeline ingesting 1.1M+ movies, 200K+ TV shows, and 200K+ production companies, sustaining 99.9% uptime.
  • Fixed a critical-rendering-path bottleneck by re-architecting the build's CSS extraction, improving Largest Contentful Paint by 56% (4.5s to 2.0s) under throttled network and CPU, and cutting render-blocking delay from 958ms to 129ms.
  • Developed a GPT-4o-powered assistant that converts natural language into live SQL against the production PostgreSQL schema at 90%+ accuracy, with a custom validation layer and SQL-injection prevention.
  • Hardened backend API security: shipped keyless service-to-service auth with Google-signed identity tokens (rather than a static shared secret), reducing the service account from project-wide edit access to zero standing permissions; closed a direct-to-origin path that bypassed the CDN's rate limiting and DDoS protection; and fixed a CORS policy that reflected any origin with credentials enabled.

Software Engineer at Awards Box

  • Optimized Nuxt SSR, Vue.js codebases, and high-impact landing pages through efficient data loading, caching, and lazy-loaded images, improving Lighthouse scores from 10-15% to 60-90%+.
  • Containerized the Nuxt.js application with Docker and deployed it on GCP Cloud Run with auto-scaling to handle variable traffic loads.
  • Set up a GitHub Actions CI/CD pipeline with pre-commit hooks (linting, Prettier formatting).
  • Integrated Stripe subscription billing with webhook listeners across the full payment lifecycle (created/renewed/expired), including automated user data backup/restore tied to subscription state, plus RevenueCat for subscription management.
