Open to Technical Lead and Team Lead roles

Technical Lead · Team Lead · Senior .NET Engineer

Hands-on technical leadership for business-critical .NET platforms.

I have 8+ years of experience across Accenture, PDI Software, and Avenga. I have owned solution design and delivery, led engineers through one-to-ones and performance feedback, and remained close to .NET, SQL Server, integrations, and production support.

Leadership scope

What I lead

At PDI and on selected Avenga projects, my responsibilities extended beyond implementation. I conducted regular one-to-ones, gave performance feedback, took part in hiring, planned team capacity, delegated work, resolved conflicts, supported career development, and owned delivery commitments.

Technical direction

Solution design, API and integration boundaries, code and design reviews, engineering standards, and modernization decisions.

Delivery ownership

Requirements breakdown, estimation, prioritization, dependency management, release readiness, and stakeholder updates.

People leadership

One-to-ones, performance feedback, recruitment interviews, mentoring, capacity planning, delegation, conflict resolution, and career development.

Production responsibility

SQL performance, monitoring, incident investigation, CI/CD, IIS hosting, Azure services, and on-premises constraints.

Enterprise experience

Technical depth with delivery ownership.

The work spans regulated and operationally demanding systems where architecture, data quality, release risk, and supportability all matter.

How I lead technical work

  1. 01

    Make requirements and ownership explicit before implementation starts.

  2. 02

    Explain technical trade-offs in terms that engineers and stakeholders can act on.

  3. 03

    Use code reviews and lightweight standards to keep delivery consistent.

  4. 04

    Stay close to production data, incidents, and support patterns.

Independent work

A small builder track outside client delivery.

These products keep me close to product decisions, customer discovery, and the practical limits of new technology.
