Experience

Technical Lead

Automation Solutionz / Remote, Canada

Mar 2023 - present

  • Cut down costs by engineering a scalable test deployment architecture, achieving 93% CPU reduction and 4000+ daily deployments through Redis-based distributed queuing.
  • Architected and launched ZeuZ's AI-powered Codebase Analyzer microservice, enabling repository analysis, artifact scanning, agentic implementation, and multi-provider LLM orchestration across Claude Agent SDK, OpenAI Codex SDK, and OpenCode.
  • Built agentic development workflows with worktree isolation, human-in-the-loop feedback, diff/commit review, PR creation, persona-based AI review, and apply/reject/continue flows for developer productivity.
  • Productionized AI services with Docker/GHCR CI builds, analyzer service routing in Docker Compose, base-branch selection, AI Jobs administration, SQL migrations, structured logging, and OpenTelemetry tracing.
  • Spearheading the idea, planning, and team-led development of an S3-compatible object storage migration away from single-host disk storage, guiding the move toward shared uploads and preparing ZeuZ for horizontal scaling and k3s/Kubernetes multi-machine deployments.
  • Implemented secure authentication system using PASETO tokens, fixing 33 vulnerabilities with 10x-30x performance improvement.

Software Engineer

Automation Solutionz / Remote, Canada

Sept 2020 - Mar 2023

  • Transformed monolithic system into microservices architecture and reduced deployment times by 75% through Docker containerization and parallel deployment strategies.
  • Engineered real-time performance monitoring using BigQuery and Looker Studio for a major telecom client.
  • Implemented the platform's first authentication layer and real-time log streaming system using Rust/WebSocket.

Jr. Software Engineer (part time)

Automation Solutionz / Remote, Canada

Jan 2017 - Sept 2020

  • Reduced frontend load size by 78% and cut report/log processing time by 90% for 500+ test cases through resource optimization and batch processing.
  • Upgraded Django from 1.8.2 to 3.1, resolving 100+ vulnerabilities in one day.

Projects

BitCode

Go, LLM Providers, Agent Tools, Terminal UI

github/bitcode

  • Built a Go agentic coding CLI similar to Codex/Claude Code with TUI/single-shot modes, multi-provider LLM backends, file/shell/web/todo/skill tools, resumable conversations, subagents, context compaction, telemetry, system reminders, and LLM-backed tool guards.

Redis-compatible Server

Rust, mio, RESP, AOF

github/redis

  • Built a Redis-compatible server from scratch in Rust with a single-threaded mio event loop, per-client buffers, RESP2 parser/encoder, command pipelining, and Redis-style commands.
  • Implemented storage internals including binary-safe values, lazy/active TTL expiry, memory accounting, AOF append/replay, and maxmemory eviction policies including Sieve.

Lorust

Rust, Tokio, RustPython, TOML

github/lorust

  • Built a Rust/Tokio HTTP load tester with rate/duration modes, TOML/RustPython flows, latency/error thresholds, structured metrics, and distributed worker/supervisor groundwork.

Proglog

Go, gRPC

github/proglog

  • Implemented a distributed commit-log service modeled on Kafka internals, with gRPC APIs and append/read semantics.

Shell in Zig

Zig, POSIX Shell, Manual Memory Management

CodeCrafters 2026

  • Side project implementing POSIX shell stages with builtin/external command execution, PATH lookup, cd support, and per-command arena allocation.

Education

American International University Bangladesh

BSc in Computer Science and Software Engineering

2017 - 2021

  • CGPA: 3.9/4.0
