CIVIL ENGINEERING + SOFTWARE DEVELOPMENT I combine international construction experience with Python/PHP development, database-backed applications, cloud technologies and workflow automation. I can support both engineering assignments and standalone software projects involving operational tools, reporting, data validation and process automation. GitHub portfolio and source code: https://github.com/celalerakman SELECTED INDEPENDENT SOFTWARE PROJECTS • CrewMetric — Python/Flask/SQLite application for workforce attendance, man-hours, production quantities, labor efficiency and capacity planning. https://github.com/celalerakman/crewmetric • SiteLedger — Python/Flask/SQLite material inventory with receipts, issues, transfers, stock counts, atomic posting and linked reversals. https://github.com/celalerakman/siteledger • WorkWeave — Project delivery and capacity planning with task dependencies, team availability, effort, historical rates and expenses. https://github.com/celalerakman/workweave • SentryScope — Python static analysis with AST rules, conservative data-flow tracking, finding history and JSON/HTML/SARIF reporting. https://github.com/celalerakman/sentryscope • CertiFlow — BOQ quantity certification and progress-payment calculations with retention and previous-payment reconciliation. https://github.com/celalerakman/certiflow • TraceLedger — Traceable BOQ measurements, reconciliation and ERP cost-code staging using SQLite. https://github.com/celalerakman/traceledger • ProcureGate — PHP/SQLite purchasing workflow with budget checks, approval controls, role boundaries and transactional audit events. https://github.com/celalerakman/procuregate • SiteQueue — Durable Python job queue with leases, bounded retries, idempotency keys and stale-worker fencing. https://github.com/celalerakman/sitequeue These are independently developed personal portfolio projects with source code and documentation. They are distinct from my engineering employment and paid client engagements. ENGINEERING SERVICES AND BACKGROUND I help contractors, consultants and project teams turn construction drawings and project data into clear quantities, practical cost estimates and reliable project controls. I am a civil engineer with nearly 20 years of international construction experience across Türkiye, Libya, Algeria and Iraq. My background covers residential developments, school buildings, industrial facilities and infrastructure, with responsibilities in site management, technical office management, planning, procurement and cost control. Services I can support remotely: • Quantity takeoffs, material takeoffs and bills of quantities (BOQ) • Construction estimating, tender preparation and bid comparisons • Progress payment review, quantity verification and cost tracking • Project scheduling, resource planning and progress reporting • Construction cash-flow forecasts and procurement planning • Excel reporting, data checking and workflow automation My tools include PlanSwift, Bluebeam, Microsoft Excel, Primavera P6, Microsoft Project and Tekla Steel. Alongside engineering, I have freelance software development experience with Python, PHP, cloud technologies and databases. This combination helps me automate repetitive reporting, reconcile project data and build practical tools for construction workflows. I hold a BSc in Civil Engineering from Atılım University. I work in Turkish and English and am based in Türkiye, seeking international remote freelance and project-based assignments. For each assignment, I focus on clear scope, traceable quantities, documented assumptions and deliverables that your team can review and use.
