Project history
â Project highlights:
?Legacy Automation & Platform Replacement:
- Eliminated repetitive manual execution of scripts and enabled faster, repeatable, auditable, and transparent operations by replacing a legacy scripting tool with a fully automated pipeline built using GitHub Actions, Ansible, and Docker.
- Developed Python-based tooling to interrogate the APIs of the legacy scripting platform, reverse-engineering its internal data model and workflow dependencies, which served as the technical foundation for automating and replacing the platform.
- Reverse-engineered business and execution logic from a legacy Progress OpenEdge application by analyzing its source code and codifying implicit workflows into Ansible automation, enabling reliable, repeatable execution without dependence on the original tooling.
?Large-scale Client Migration (300+ tenants):
- Significantly reduced post-migration data discrepancies and cut down troubleshooting effort during the migration of 300+ enterprise clients to Progress OpenEdge 12 by implementing automated validation checks.
- Developed PowerShell automation to enable fast, large-scale migration testing, replacing manual single-client checks, accelerating test cycles, and ensuring smoother production cutovers with fewer production incidents.
- Implemented a layered internal infrastructure delivery platform for a regulated investment data processing system, combining hardened base images, reusable infrastructure modules, configuration archetypes, and controlled deployment workflows.
- Established secure, standardized server baselines by building CIS-hardened Windows and Oracle Linux golden images using HashiCorp Packer, reducing configuration drift and ensuring compliance-by-design.
- Developed reusable Terraform/Terragrunt infrastructure modules to provision consistent multi-environment infrastructure patterns across Azure and on-prem environments.
- Defined server archetypes and standardized configuration roles using Ansible, transforming ad hoc configuration into version-controlled, reusable infrastructure components.
- Implemented Git-driven infrastructure workflows (GitHub Actions + PR-based change management) to enforce review, traceability, and automated reconciliation of infrastructure changes.
- Designed controlled cross-platform release orchestration by integrating GitHub Actions with Octopus Deploy, enabling deterministic, auditable deployment flows across hybrid environments.
- Built observability and validation tooling (Python & PowerShell) to proactively detect integration failures and enforce reliability across distributed services.
- Resolved complex production issues in a Forex trading application, primarily related to Open Banking API integrations, data discrepancies, and application behavior, ensuring platform reliability and data accuracy.
- Accelerated incident investigation and knowledge acquisition by instrumenting MongoDBâs Oplog in a development environment using a Node.jsâbased monitoring script, mapping application UI actions and trading events to underlying database changes in an undocumented schema.
- Improved application availability and incident response by collaborating with DevOps teams to implement monitoring and alerting, enabling earlier detection of failures.
- Designed and implemented an on-call rotation using Opsgenie, ensuring rapid incident response and reduced time-to-resolution for production issues.
- Enabled data-driven troubleshooting and business insight by extracting custom reports from MongoDB using the Aggregation Pipeline.
- Reduced recurring incidents by performing post-incident analysis, identifying root causes, and feeding actionable findings back into development and operational processes.
