Experience
AdoptSequence & AdoptIQ (Curtis Digital Inc.) — Remote
Led architecture and platform engineering for two SaaS products: an onboarding/automation platform and an A/V enhancement workflow service.
- Led backend migration of AdoptSequence from AWS Lambda → Trigger.dev to support long-running video processing.
- Built a public content-sharing system with Astro + Cloudflare Durable Objects; optimized for SEO and low global latency.
- Architected end-to-end audio/video enhancement workflows using FFmpeg, Whisper, and AI voice synthesis.
- Integrated Supabase for real-time sync and Postgres storage; replaced Ably, lowering latency and cost.
- Operationalized RUM + APM in Datadog with CloudWatch signals; guided devs to review error patterns, improving iteration speed by ~50%.
- Implemented PostHog-based interaction analytics with Kafka ingestion, ClickHouse OLAP, and Redis caching; authored the event schema and ETL, reducing time-to-activation and improving onboarding efficiency.
- Developed a modular onboarding SDK (Shadow DOM → Lit Web Components) and a lightweight Chrome extension to test/debug onboarding flows.
- Owned the full DevOps lifecycle: CI/CD pipelines, infrastructure automation, deployment strategy, monitoring, and cloud cost optimization across AWS and Cloudflare.
- Managed multi-repo codebases on GitHub with standardized PR reviews and automation.
- Mentored junior developers, enforced best practices, and led roadmap execution with founders.
Colliers International (via TopCoder) — Remote
Modernized internal apps for a global commercial real-estate firm, replacing third-party tools with Azure-native and AWS-native services.
- Replaced a 3rd-party valuation tool with an internal AWS solution (EC2, S3, SES, RDS) in 3 weeks; cut vendor cost ~60–80% and absorbed additional developer cost solo.
- Architected microservices on Azure Functions backed by Cosmos DB + SQL Server; reduced API p95 latency ~30–50%.
- Implemented IaC + CI/CD with Terraform and Azure DevOps.
- Mentored engineers and led POCs with architects/BAs; reduced new-hire ramp ~30–50% and accelerated concept-to-pilot ~2x.
- Drove code reviews and onboarding standards; PR cycle time −20–35%, post-release defects −20–40%.
Relisource Inc. — Dhaka, Bangladesh
- Actively mentored team members on architecture and clean code practices.
Astha IT — Dhaka, Bangladesh
- Led development for enterprise systems in logistics, education, and fintech.
- Mentored junior engineers and participated in system architecture, client demos, and delivery cycles.
