Hi - I'm Manas Kalangan

Seeking Full-Time Software Engineer roles starting June 2026. I partner with product and engineering teams to ship reliable backend services and automation that move business metrics - not just code. Check out my portfolio

About Me

  • Product-driven engineer with 2+ years of hands-on experience delivering backend systems, infra automation, and developer productivity improvements.
  • Proven impact: reduced operational escalations by ~30%, accelerated slow test suites by up to 90%, and remediated thousands of production defects.
  • Comfortable owning the end-to-end lifecycle: requirements → design → implementation → monitoring → iteration

Contributions

Check out my open-source commits to Ginger (automation testing tool)

Projects

ArtAtlas - Explainable Hybrid Art Search Engine : demo

  • Designed and built a local-first, explainable retrieval system in Python that cleanly separates candidate retrieval, result ordering, and evidence-based explanation into independently auditable layers.
  • Implemented hybrid search using PostgreSQL FTS and vector embeddings (pgvector), augmented with a human-curated concept layer to ensure deterministic behavior without opaque LLM reasoning.
  • Built runtime Evidence Bundles and a validated Explanation Graph to attach explanations only when supported by traceable evidence, without blocking or distorting retrieval results.

News Feed Service - Twitter-like Timeline Service : demo

  • Designed and implemented a scalable news feed service, modeling Twitter-style timelines with a hybrid fan-out strategy to efficiently support both normal users and high-follower users.
  • Implemented an asynchronous write pipeline that persists posts and offloads fan-out processing to Kafka consumers.
  • Developed a read-optimized feed service that merges Redis inboxes with the pulled posts from high-follower users.

Progression Palette - Emotion-Aware Music Generation System : demo

  • Designed and built an explainable, emotion-conditioned chord progression generator using Roman numeral harmony and functional analysis, avoiding black-box ML models.
  • Implemented probabilistic sampling over harmonic patterns, ensuring that identical prompts produce variety.
  • Designed an experimental emotion-aware harmonic decoration mechanism that adjusts chord extensions based on interpretable emotional axes

Highlights

  • Reduced production escalations by ~30% by designing and deploying reliable, fault-tolerant .NET 8 services (Rocket Mortgage)
  • Accelerated test suites by up to 90% by optimizing automation workflows within the open-source Ginger testing framework.
  • Resolved 3,000+ production defects & 300 critical bugs, strengthening reliability and customer trust
  • Increased product quality and release confidence by boosting UI & automation test coverage by 60% (Selenium & MSTest)
  • OCR & docs - Redesigned OCR pipeline to improve PDF text clarity by ~40% (Amdocs testing feature)

Systems & technical scope

  • Languages & frameworks: C#, .NET (Web API/ASP.NET MVC), Node.js/Express, TypeScript, React, Python
  • Data & storage: SQL Server, MongoDB, Redis, PostgreSQL
  • Cloud & infra: AWS Lambda, Terraform, Azure DevOps
  • Testing & observability: MSTest, Selenium, automated test optimization, logging & metrics-driven rollouts
