Khatoon
Software Engineer
I'm a software engineer with a B.Tech from NIT Warangal. I build distributed systems, microservices, and full-stack applications with a focus on reliability, security, and clean architecture.
From certificate lifecycle management across multi-cloud environments to kernel development and compiler engineering, I care about software that works at every layer of the stack.
Seaionl Inc
Software EngineerDeveloping CertPing, a distributed SaaS platform for PKI and certificate lifecycle automation across multi-cloud and on-prem environments. Building event-driven microservices for SSL/TLS operations with third-party API integrations, plus orchestration across notification, scheduling, monitoring, domain/DNS, billing, support, and auth systems.
Athena Tech Systems
Software Engineer InternBuilt a Java APM platform tracking JVM KPIs via a JMX/JFR-based sidecar agent and a Kafka pipeline backed by TimescaleDB and Redis, exposing telemetry to downstream dashboards.
NIT Warangal
AI/ML Research InternBuilt an end-to-end machine-learning pipeline for predicting expensive CFD simulations across 1,800+ runs. Achieved 99.99% accuracy with MAE of 0.00048 and MSE of 0.00057.
SamOS
↗A multitasking kernel with a bootloader, IDT, preemptive scheduler, 4-level paging, multi-arena heap, syscall layer, ELF64 loader, VFS with a FAT16 driver, PCIe ECAM (ACPI MCFG), NVMe + PATA disk drivers, PS/2 keyboard + mouse drivers, an event-driven window system, and a static userlib plus shell program.
SamCompiler
↗A C compiler with a custom lexer, preprocessor, recursive-descent parser, tag-union AST, semantic validator, identifier resolver, and an x86 code generator emitting NASM under the cdecl ABI.
SamTcpIp
↗A userspace TCP/IP stack implementing ARP, IPv4, ICMP, UDP, TCP with congestion control, a Path MTU Discovery cache, and VLAN tagging on Linux TAP devices.
SamDB
↗A persistent database with a copy-on-write B+tree, durable two-phase commit, a page-organised free list, typed tables, secondary indexes, multi-statement ACID transactions, and MVCC snapshot isolation.
SamMLD
↗A memory-leak detection tool that tracks dynamic allocations and identifies unreachable objects by analyzing object graphs, reporting leaks back to their source.
