Distributed infrastructure, backend systems, and performance engineering

Building calm, reliable software for complex backend systems.

I am Aaditya, a distributed backend engineer from Lalitpur, Nepal. I work on event-driven architecture, fraud and transaction pipelines, distributed infrastructure, open-source collaboration, and low-latency execution paths where correctness matters as much as speed.

Snapshot

Lalitpur, Nepal
Founding Engineer at Flint Secure and Project Lead at NepBrains

3.2k rps

Validated staged risk-scoring workloads with sub-50ms P95 latency.

10k+ ops/s

Tested synthetic write spikes for backend SaaS transaction pipelines.

99.6% PDR

Observed in wireless mesh CRDT synchronization experiments.

Distributed Systems

Event-driven systems, state consistency, fault tolerance, and recovery behavior under network boundaries.

Backend Engineering

Go, Node.js, Python, PostgreSQL, Redis, and NATS for production-grade transaction-heavy systems.

Performance Thinking

Synthetic load validation, profiling, low-latency critical paths, and deterministic execution analysis.

About

Engineering systems that stay understandable under pressure.

My work sits at the intersection of backend architecture, distributed infrastructure, and execution performance. I enjoy taking ambiguous, failure-prone systems and making them measurable, deterministic, and easier to reason about.

Beyond product work, I write and speak about microservice migration trade-offs, decentralized synchronization, open-source collaboration, and the engineering patterns behind resilient systems.

Education

Nepal College of Information and Technology

Bachelor of Engineering in Computer Engineering · Expected 11/2028

Coursework includes data structures and algorithms, operating systems, database systems, distributed systems, and object-oriented programming in C++.

Beyond Work

Lead author on CRDT replication research for infrastructure-less wireless mesh networks; international speaker on microservice migration trade-offs and at Saint Xavier's, Everest College, Phoenix, and NCIT; and advocate for open source across TEDxNCIT, GDG Kathmandu, Ubuntu Nepal, GNOME Nepal, and NOSK.

Community

The part of my work that happens in public, with people, not only in code.

This is the missing part. Your site should not only show systems and benchmarks, it should also show the communities, talks, research, and ecosystem work that shape how you think and contribute.

Experience

Professional work shaped by systems thinking.

I work across fraud infrastructure, SaaS modernization, cloud automation, and architecture that has to remain stable while the load or network conditions change.

Dec 2025 - Present

Founding Engineer, Backend & Infrastructure Lead

Flint Secure

Co-architecting an event-driven backend for fraud detection and transaction intelligence with Go, Python, PostgreSQL, Redis, and NATS.

Highlights

  • • Validated staged workloads near 3,200 requests/sec with sub-50ms P95 decision latency.
  • • Reduced automated transaction validation latency from around 200ms to under 50ms.
  • • Built graph-based fraud relationship analysis across devices, accounts, and identifiers.

Aug 2024 - Present

Project Lead / Full-Stack Engineer

NepBrains Pvt Ltd

Leading modernization of legacy systems into structured services while shipping SaaS platforms with React, Node.js, and PostgreSQL.

Highlights

  • • Validated backend transaction pipelines against synthetic write spikes above 10k operations/sec.
  • • Automated CI/CD with GitHub Actions and Docker to reduce deployment overhead.
  • • Configured CloudWatch-based monitoring for high-availability operational targets.

Mar 2025 - Jul 2025

API Engineering Fellow

Keploy Inc.

Selected for an API engineering fellowship focused on automated testing workflows, distributed system validation, and open-source contribution.

Highlights

  • • Integrated 5+ enhancements into Keploy's open-source core through GitHub contributions.
  • • Improved automated API test harness generation and pipeline execution efficiency.
  • • Earned a distinction badge for scalable API design and automated test generation.

Apr 2025 - Jul 2025

Writing

Writing on systems, software, and resilience.

I write about distributed systems, backend architecture, offline-first design, low-latency execution, and the trade-offs that show up when software meets the real world.
